Rubrik Valuable Features
System Administrator at a manufacturing company with 51-200 employees
The most valuable feature is the Instant Recovery, where we can restore a VM or SQL database or any server or application, and have it up and running on their appliance within a few seconds. The recovery time of the instant restore is instantaneous and there is no complexity to it. What we're recovering doesn't matter to them, and we don't have to wait for it to mount a recovery image or do anything like that. When they say instant, they mean instant.
The ease of use is important to us, as well. It's super easy to get set up. Within a few hours of them deploying the on-premises appliance, we were backing up data locally into the cloud and able to test restores.
Rubrik is really good about releasing updates and we have had no issues with the process. They make it very easy, working with their support when they do put out an update, and they assist with doing the health checks beforehand to ensure that there are no issues. They do a pre-flight check on those updates to ensure that they're compatible with the appliance. Then, we schedule a time off-hours to apply it. They are normally pretty quick and we've never had issues where we had to roll back. They've always been flawless updates.
The CloudOut technology allows us to replicate data in our environment to the cloud, and then it can be spun up and used in the cloud if our physical environment is not available.
The VM backup and the SQL backup are blazingly fast for both backup and recovery.
The web interface is really good. and it's only gotten better with every update. It was good, to begin with, but they've improved the speed and added features in each update. It is a modern interface that works in any browser, and we can get to it from a tablet or computer. The type of device you access it from doesn't matter because it fits all screens, and it's intuitive and easy to use.
The archival functionality is very good. It is very easy to archive data to the cloud, and this is something that we were looking for. You can do it all from their web interface, which is a plus. You don't have to jump into the command-line interface or run scripts or anything to make it work. It is all configurable in the UI and very easy to dump data off to the cloud and pull backups back from the cloud archives.
We have used the predictive search functionality and hands down, it's the easiest way that I've ever recovered files. It's just like searching Google, but it searches your own files for recovery. It's easier than if you told somebody you could use a Google-like search to recover files, I don't think they would believe you until they've used Rubrik, because it does work that well. It's quick to search, no matter if you're searching a VM or even a physical box, it works across them.
With their new global file search in the latest version of their CDM, you don't even have to know what host that file was on. You can just type in a file name or a part of the file name and it'll find it. When a user comes and says, "We lost the file and it was called something like this," with any other solution, I don't know how you would find it. I think it would take a lot of work. With Rubrik, within a few seconds, you have file results. It's a pretty great feature.View full review »
Storage Administrator at a healthcare company with 5,001-10,000 employees
We do like the instant recovery because, beforehand, we would tell people, "Hey, it's going to take anywhere from 30 minutes to an hour to spin this up and, in that time, we're going to need your help with certain questions." We would sit there and work with them, but it always took quite a while. Now, we say, "Okay, give me 15 seconds and I can get this back up for you." And within that 15 seconds it's on and the only thing that we have to do afterwards is vMotion it off of the Rubrik storage back to where it should rest.
We also like the web interface. We mainly log in to the node and work from that, but occasionally we will log in and look at things when offsite. It's very intuitive and it works really well.
In addition, the solution's APIs play in with our automation piece for hybrid cloud. We wanted everything to work without manual interaction. We wanted everything to just play through when a ticket is submitted and automatically spin up the backup that we wanted, based on the tag in the VMware object. Our VMware team was the one that mainly looked at those APIs and built all of that out, but they haven't had any issues with it. It's worked exactly as designed.View full review »
There is a live-restore feature, their Live Mount, and the way it works we can instantly recover a VM, a past backup, to be directly attached to our VMware environment. Rubrik will act as a disk for it. It's like an instant restore. Within a few minutes our VM is up and running. And then, if we want to restore it, we can just migrate it to our actual storage.
Rubrik's web interface is very simple to use. We have a very simple SLA configured so that everything is backed up every day. Any new VMs we configure in our environment automatically get added, the SLA is automatically assigned to them. All the VMs, after three days, are archived to AWS S3, and then there's a life cycle on the AWS side to work with that.
The archival functionality is one of the main features because the Rubrik that we have has about 60 or 70 TB of total local storage, which is definitely not enough for our data. We have around 140 TB of data stored on AWS and, without the archival feature, we would have to buy at least three times the number of nodes that we currently have to keep all the data secure for 42 days, based on our SLA. It's definitely saving us on costs. It also gets us away from having to keep redundancy on the data, because if we were storing it on-premises we would have to make sure that we have redundancy and offsite storage. Now, all of that is AWS. We no longer have to worry about that.View full review »

It backs up everything to Azure, so we no longer have to worry about tapes. When we went into lockdown, as a response to COVID, we didn't have to think about, "Well, we need to send people into the site to change backup tapes." That all carried on working. We could do a lot more remotely than we would have been able to do otherwise.
We also have the Radar product for ransomware detection. That looks for anomalies in our backups and will trigger an alert if it sees something that is an abnormal amount of change. That could be lots of deletes or modifications, compared to normal. Or it could be some VMs that have suddenly had a lot of folders added or deleted. We haven't had anything so far, at least, that was problematic, but it's nice to know that it's keeping an eye on how much change is happening with backups and helping us identify problems. It can detect when someone has gone in and deleted a substantial amount of data on a VM. If that's abnormal it will flag it and say, "Well, you might want to investigate this."
Our finance was doing a big refresh of non-production data. They deleted a load of log data and the app flagged it and said, "Well, this is strange activity. You might want to just check this out." I referred that to the finance team and they said, "Yeah, we're just refreshing the VMs, that's okay." That was cool, because we moved on. But if they had said, "Well, no one has touched that for months," then we would have looked at it in a bit more detail to see what it could have been. But without that alert, we wouldn't have any clue that anything happened. It's helping us keep an eye on what's normal and not on the estate. It's worth it because it doesn't always have to be external actors that are causing problems. You could have somebody internal being malicious if they're looking to leave or dissatisfied in their role, for example. It helps keep an eye on those situations as well.
Its web interface is really easy to use. It's just click and go. It's fast and intuitive. We've never had any problems in navigating.View full review »
Director of Technology at a financial services firm with 201-500 employees
The most valuable features are reliability and programmability. We have a great success rate for backups with Rubrik and because of the ease of automating tasks, we also run periodical restores to check the quality of the backups.
Rubrik makes it really simple to automate the restore task, which is important because I don't care about the backup. I care about the restores, and Rubrik did a great job of assuring restore reliability.
Our time spent on recovery testing has improved simply because we're able to automate it. It saves us between two and four hours per week, whether it is simply adding a new machine or going through the logs and seeing what failed.
We don't do recovery on a daily or weekly basis. We receive between two and four recovery requests per month. Because it is mostly manual stuff, it is comparable to the old system if we're talking about restoring something within a two-week timeframe when it's still on disk. However, if we're talking about restoring from the cloud versus restore from tape, the timeframes are not even on the same level. This is simply because we use the offsite storage for tapes, so sometimes the restore task from tape will take weeks.
The web interface is easy to navigate and pleasant to look at.
The SLA-based policy has simplified our data protection operations tremendously. It goes back to caring about restores instead of backups, and the fact that it allows me to easily drop systems into the SLAs greatly reduces the amount of time it takes to set up the system for backup.
It allows me to create a protection policy and while it's running, I know that the systems that I've assigned to that policy are being protected accordingly. If that is not happening then I get an alert or a notification telling me that the systems are outside of the protection horizon. It's a great approach.
The archival functionality is impressive. Just by eliminating reliance on the tape technology, it's greatly improved the rate of successful restores that we were able to perform. In two and a half years, I can't remember a case where we couldn't locate data that was backed up using Rubrik.
We have not needed to use the ransomware recovery function but I know that Rubrik backups are essentially immutable. Even if an intrusion does happen, we'll be able to restore the data quickly.
I have used the rapid restore functionality and I noticed that on many occasions, I was able to mount a virtual machine or database on the Rubrik cluster itself. So, I know its high-speed connectivity options are excellent and support VMware well.
With the previous version, we had to do some Python scripting because the API was better and more developed than the PowerShell support. However, with the new version, it seems that PowerShell covers all of the functionality that we need, which is great, especially because we are a Windows shop.
The restore success rate is very good. I don't care so much about improving the time spent on the resource. Rather, it's the success rate. At this point, we have a 100% success rate, which was definitely not the case with any prior system that I've used.View full review »
Senior Technology Architect at a comms service provider with 1,001-5,000 employees
Rubrik's web interface is an eight out of 10. It is very easy to use, clear, and responsive. You don't need to click into many different places to get the information that you are looking for; it is intuitive. I like it a lot.
The SLA-based policy automation that Rubrik brought to market five years ago was really a game changer. In the previous backup product, you always managed your backups on a job basis, so what you needed to do is, to say, "Okay, I'd like to backup that specific workload, but I need to stop at this time." With Rubrik, it is completely different. You just need to configure an SLA, saying, "Okay, I would like to have a daily backup," or "I would like to do a backup every six hours. However, Rubrik, start when you think it's the most appropriate time." Then, you don't need to manage maintenance or backup windows anymore. In our environment, where we have based our data centers in the US, Europe, and Asia, it is not a headache anymore to configure our backup jobs, since Rubrik deals with it. When you configure the Rubrik environment, it is a few clicks. Then, you are good to go, and it's already doing backups by itself.
The solution’s archival functionality is very interesting because you have a lot of options. You can either archive on-prem or in the cloud. On-prem, you have the choice between object storage and block storage, which is nice, as it fits any environment. Archiving in the cloud is very easy as well. There is no support in GCP and AWS history in Glacier, so it is a very good option.
It is easy to offload your local storage. If your brick is becoming full, you have two options:
- You buy an extra brick, expanding the cluster, but it has a cost.
- You can decide to archive your data. This means that the snapshots that you have on the Rubrik cluster can be migrated to another place. Another place can be either in the same data center or in the cloud. This is a great option, and we are using it.
We are scripting a lot using the Rubrik API to gather some information about usage, monitor what is going on, or do some very specific actions, like initiating a backup from the command line within a scripted environment. So, it is very handy.
There is a search feature inside the cluster. So, if you want to restore a specific file from a snapshot, you can then do a search inside the snapshot. The time that it takes to find and recover applications/files is almost instant. In the previous backup software that we were using, we didn't have the ability to dig inside and browse the snapshot, or even search inside the snapshot to find the required file. We can find instantly what we were looking for by searching inside a snapshot because Rubrik is maintaining a metadata DB where we can find anything that we want. Whether it is on-prem or archived already in the cloud, we can find anything using this search mechanism.View full review »
The ease of use and innovation are the features that stand out for us. It provides the capability to drive down to the end-user, service desk level one, and use the system with minimal training.
The web interface is excellent, and we really like it. The Google search, capability for file restore, and the ability to integrate the API into third-party products are really good.
The archival functionality is excellent, supporting all the major cloud vendors. For our situation, it supports pretty much all of the archival methods that we would want to use for long-term retention. We archive data for up to seven years.
We have used the API support for integration with vCloud director to create a tenant self-service portal. Our next project will be looking into automation with ServiceNow.
We have used the predictive search feature and it drastically reduces the time it takes to find and restore data for people. It used to take perhaps hours to hot mount an image and then search it for a file. Now, we use the Google-like search to look not only across an individual VM but across the whole environment, with all of the VMs. We can find any file across terabytes of data in under 30 seconds and have a restore done, depending on the size of the file, in generally under five minutes.View full review »
Sr Storage Administrator at a insurance company with 501-1,000 employees
The recovery is the most valuable feature. The interface is very clean, streamlined, and simple to actually perform a recovery. It's four clicks away from being done, depending on what you want to do. That's on something that is already automated on top of that. All of the backups are already automated, so when something comes up and someone's requesting a backup or recovery of a server for whatever reason, it takes very little time to get in, find what you're looking for, and get it done. It's not a drawn-out process.
The web interface is very intuitive. I compare it to an iPhone. Everything is where you expect it to be. The main tabs are very well laid out. The drop-downs inside of those tabs make sense. It's very easy to use and it makes sense. It's not the traumatic experience of older products.
The learning curve is incredibly short. The beautiful part about it is that it makes sense so that you don't have to use it every single day to be able to go back in and do what you want to do. There's a lot to be said for that.
I use Rubrik daily to ensure that everything backed up as expected. I look to see what may or may not have backed up and why. I do that aspect now a lot more. I do backups periodically when the main contact is not available.
We use SLA-based policy automation. It solidified our data protection operations. That alone gave us the ability to simplify and streamline the process. We were able to come down with independent SLAs that met the specific needs for whatever department or server was being protected. Whether it's production, DevTest, utility servers, whatever the case is, there are individual SLAs that we're able to make simple changes at the wholesale level, if we need to. Once they're set up, they're good to go. It makes things very easy and we can set up a bunch of them which makes life tremendously easier.
In terms of the archival functionality, we pushed things off to S3 and it works. At that point, when you're bringing things back from archival, that can be a little slow, but that's a matter of things outside of Rubrik's control. It depends on what it is, where it's at, how old it is, and what it is you're paying for.
Predictive Search to find servers makes life so much easier. We're able to drill down and put it in a simple part of whatever server name it is. A lot of times people need the server restored. We check the server name and they give us some name that's not exactly the technical server name. We're able to fish down and find what we're looking for much quicker than trying to rely on them to give us the proper name. The Predictive Search definitely helps everywhere.View full review »
Their Live Mount technology uses Rubrik as storage, while using our Cisco UCS Blades as compute for rapid restores of backups, which is really awesome. That is one of the biggest value-adds that Rubrik provides. It saves time as well as being easy and works well. Our previous backup solution restores were cumbersome, time-consuming, and labor intensive to do. They required a lot of validation. With Rubrik Live Mount, you can restore a system in well under a minute, whereas it would take up to hours in the past.
Live Mount is where we do the majority of our big recoveries, unless it is a file recovery. A file recovery takes a few minutes to restore to where the file in the event a file was accidentally deleted by a user, etc. There has been at least a 90 percent reduction in recovery time based on our previous solution, from the need to recover something to when it's actually recovered went from hours to minutes.
We really like their SQL tools around SQL Server as well as the ability to do transaction log backups and restore to a point-in-time based on those transaction logs. We also like the restore options: restoring in place or mounting a database to another server. Their toolset around SQL Server works really well.
We like the web interface a lot. It is simple, but powerful.
We like the solution’s archival functionality. We currently archive offsite to an NFS store in one location and a cloud S3 location for some other objects. We have been happy with the way that both of those work.
We have used their search, which is powerful.View full review »

From a security point of view, data is highly-encrypted using the Rubrik security solution. Therefore, we don't have to worry about any image/data loss or data leakage.
If there is any corruption of the snapshot, e.g., the target is corrupted while taking the snapshot, Rubrik is our faster option to have two snapshots: snapshot one and snapshot two. If there is some issue with snapshot two, then we still have the option to restore the data to snapshot one. In this way, we never lose the customer's trade data.
Rubrik's web interface is very user friendly and easy to use with all its navigation, e.g., it is easy to identify if you're looking for any help. So, the help features are there. The customer support feature is very nice. We are regularly using that. The alignment of all the fields of the platforms on the Rubrik GUI are very good.
Its archival functionality is very nice. On a regular basis, we snapshot our VMs and server logs. So, we keep archiving the logs and snapshots into Rubrik for archival functionality on a monthly basis. For 30 days, we maintain the snapshots of our data using the Rubrik archival functionality. Whenever we need to retrieve any snapshots that have been stored for the past one month, we can easily retrieve them. The retrieval process is also very fast from the archival function, and it doesn't take too much time.View full review »
- Backs up all our platforms.
- Its ease of use and single pane of glass management.
- Lowers our overall management costs; we don't have to look after it anymore.
The solution's web interface is clean, simple, and easy to use.
Its archival functionality is great. We have used that from day one for Azure. The cloud backup was one of the key reasons to switch.
We use their predictive search. It is very much like your standard, usual search engine type approach. You can type in simple English and get results back from that. The easier the interface is to use, then the more time is saved in other peripheral tasks.View full review »
It allows for easy integration. We use NetApp, so it integrates with NetApp snapshots. It is very easy to set up and start backing up. You don't need to do custom configurations. It's simple and straightforward compared to traditional backup solutions. It's easy to adapt the user interface and easy to navigate. It has good reporting. It also has nice monitoring. My dashboard is also very good.
The SLA-based policy automation is a good way to create different policies, such as retention, frequency of backups, or retention of backups based on the data owners' need for protection. We create different SLAs based on our requirements for data. And then when we need them, we find the appropriate SLA and just attach them to this SLA which makes it easy. You don't need to create a policy for each resource. You basically group your resources under the SLA.
The Archival feature is very good. Rubrik requires you to have at least one local copy on the Rubrik break, but then you can archive either to basically any storage. They also integrated clouds like Azure and AWS, where you can archive to a different tier. So you can apply archiving to F3 for something that you may need for faster recovery.
We, fortunately, didn't need to use Rubrik for ransomware. We also own Rubrik Polaris Radar, which creates a report and looks into our environment and any suspicious activities that could be related to ransomware so we can check right away. And if it's a real vulnerability, we can address it in a timely manner. We didn't have to do anything to recover from ransomware yet, but I feel like we are better protected now with Rubrik Polaris Radar.
The feature that I found most valuable is Live Mount. You can either mount a virtual machine from a snapshot, or you can mount a volume from the snapshot. You can mount one disk to the server to retrieve data, or you can mount the whole VM, rename it, and use it as a test VM. If your VM gets corrupted, you just mount one from the snapshot, and you have your production VM's backup. So, Live Mount is definitely the best feature for me as an end-user.
Another feature that I love is their ransomware detection. Rubrik has one of the best ransomware detection out there.
The backups are immutable, and nobody can change them. You can't override them. You can't change anything in the backups once the snapshot is taken. Our backup retention is 120 days. So, for 120 days, nobody can change that. When I take a snapshot of a server, if the next day we get hit with ransomware, I could shut that down. I can then just stand one up from the backup that I took yesterday. They can't change anything that is already in the backup.View full review »
Senior Systems Manager at a construction company with 1,001-5,000 employees
It's hard to specify a feature that is most valuable. The overall architecture is where we find the most value. Having an API-centric approach has allowed us to utilize a lot of automation to trigger the capabilities of Rubrik. This helps us minimize the operational overhead of managing and restoring backups. We have integrated Rubrik with our ticketing system and have some custom triggers to present Dev/Test environments from Rubrik to our development team.
The web interface is extremely intuitive and, with recent changes to the API, it has become more responsive than it was when we initially implemented the product two years ago.
We love the archival functionality and we utilize it a lot. We archive out to Azure Blob Storage to have an additional layer of protection and extend SLA times.
From an information security and business continuity perspective, the solution’s ability to recover from a breach, is one of the biggest features of the product. We don't have to worry about the operational complexity of air-gapped backups and can rely more on the immutability approach. It is a highly valued feature in this solution.View full review »
The most valuable feature is the speedy restore. It helps in expediting RPOs and RTOs across our core applications.
I would rate the solution's web interface at eight out of ten. It's just fantastic and intuitive. It's so easy to use. I've never done any formal training on Rubrik, but I was able to quickly come to grips with its capabilities. That's a fantastic thing, especially for somebody who is just looking to adopt it, because they don't have to worry about training for their wider support function.View full review »
Network Specialist, Information Technology at a university with 1,001-5,000 employees
The simplicity of the SLA design is the most useful feature. You just set it and you don't need to come back to it again or worry about it.
The SLA-based policy administration has helped us to adjust the workflow, saving us time. This is because what we have right now is that we set up an SLA based on what the appliance does; for example, it might be an SQL server or an application server.
The web interface is user-friendly, clean, and it provides a good summary of what you're protecting at a glance. It also shows you whether there are jobs running, or not. It is my daily task to look at the web interface to monitor our status.
We use the archival functionality and it seems to work fine. We don't see a conflict with it.
The integration with EMC Isilon works well and it's a really great idea to have Rubrik take the snapshot not just on its end, but on the appliance end, and be able to retrieve it.
We used the predictive search functionality and find that it makes things easier to do. We save a lot of time in trying to figure out whether we need to download a file first, or whether we need to unarchive it.

The feature that I have found most valuable from Rubrik is its protection against ransomware attacks. Rubrik is a very nice, very good solution because it is able to protect your data and you have the possibility from the backup to detect any abnormal behavior, like a ransomware attack. You are able to detect and restore very easily with this solution. This is a major differentiator in comparison to the other competitors.
Rubrik is a cloud based solution and the main differentiator for Rubrik in comparison to the others is that you do not have to configure your backup job, you just have to set up an SLA, Service Legal Agreement, and Rubrik has matching learning and AI, Artificial Intelligence. Rubrik then does maximum automation of these tasks. You have a multiple feature, including a search engine, like a Google search engine in the UI, and I think this is a very modern approach. Rubrik has a very modern approach. Rubrik is an all-in-one solution for your backup so you don't have to think about how to configure the architecture. Because Rubrik is a scale out solution, you just have to pay for an all-in-one solution, starting with a small brick and growing with your needs.
You can start with few needs, and if you need more resources or more power, you just have to put another brick and the merged cluster grows automatically. In comparison to other solutions, you do not need to think about how to grow your architecture. With Rubrik, you don't have to think. If you have resources or more storage, you just have to buy a new brick. You put this new brick in the existing cluster and the whole system is configured automatically.View full review »

What I like about Rubrik is that you can back up to the cloud. It is a different kind of backup where you're not archiving the tape. Rubrik is a physical appliance. It is a dedicated appliance to which you can back up, and you can also back up to another device. So, you can back up to Rubrik and then to another device. If you have more than one site, you can set up Rubrik on site A and also on site B. You can back up to the Rubrik on site A and then replicate that data to the Rubrik on site B.
I like it. There are so many functions. It can also be used as a file server. It is a physical appliance. It is a backup device, but it can also be used as a file server. It can back up a file share.View full review »
