We use it to protect our file and email servers. It provides excellent deduplication features.
Pros and Cons
- "The feature that I have found most useful is its data duplication."
- "When you use Data Domain, you have to have at least 20% free space so it can work properly. Sometimes we struggle with that, because we wanted to use all the free space, but then Data Domain becomes really slow. I understand that 20% is needed to process all the data, and doing the duplication and compression and all that, but it would be a big improvement if they did not require that 20%, because it is just too much to have available."
What is our primary use case?
We as a company use this product to protect our information. We have Data Domain combined NetWorker for our own company, and we also install and provide services around those solutions to our customers.
In our company, Dell Data Domain is used to protect our servers (on-premises), where the most important servers for us are the File Server and the eMail server. The Dell Data Domain we have It´s combined with Dell NetWorker as the backup software. The Data Domain works as the repository of the information, taking advantage of the duplication and all the features that it has. We are getting about 30x as the deduplication ratio. It is managed by the software NetWorker, where all the backup policies reside. We have clients in all the servers directing information from the server to the Data Domain taking advantage of the software client direct feature. We make backups on a daily basis, as incremental backups, and over the weekend we have full backups. We have about 14 servers in our office. Mostly Windows and Linux.
How has it helped my organization?
Yes, Dell Data Domain has improved our organization's backup strategy. As I mentioned, our infrastructure has different types of servers, all of them are virtual servers based on VMware. Once we had to make a recovery and we used the Instant Recovery feature where we started the virtual machine over the Data Domain instead of the VMWare server. Then we used VMotion to move the virtual machine from the Data Domain to the VMware server. We were able to minimize the service failure to 15 minutes approximately.
What is most valuable?
The feature that I find the most useful is its data duplication. We had been having problems doing backups for the file server because we did not have enough space to store our backups. Data Domain solved that problem for us.
What needs improvement?
In terms of what could be improved, when you use Data Domain, you have to have at least 15% to 20% of free space so it can work properly. I understand that space is needed to process all the data, but it would be a big improvement if we could use that space too.
For how long have I used the solution?
Just to give you a little background, I work for an integrator and we are also users of the technology. We have installed and used Data Domain for five to six years now. We also provide installation and support services for Data Domain for our customers.
What do I think about the stability of the solution?
I think it is awesome. We've been using Data Domain for almost five years, and during this time we have only had one problem with one disk. We reported that to Dell and they sent us the replacement part and we only have to exchange the disk with the failure.
What do I think about the scalability of the solution?
We are looking at the scalability right now, because the family of Data Domain we have is already being replaced, so we are looking at changing the Data Domain. It seems that the upgrade will be easy, but we are still planning how to do the upgrade.
How are customer service and technical support?
Sometimes it's difficult to reach the real experts to get a solution. The escalation process is not that great, but in the end, it works.
Which solution did I use previously and why did I switch?
Tape based backups
How was the initial setup?
I installed the Data Domain and it was really easy.
It is not a big Data Domain, so it was just mounted in our rack. We followed the initial setup where the IP and the name are configured. After that, most of the configurations had to be done over the software.
The complex part of the configuration is in the backup server (software part), it is not in the Data Domain. The Data Domain was really easy to set up. The Data Domain setup took us about four hours.
Our deployment plan was based on the installation of the hardware first, and after that, the software deployment, starting with the backup server.
What about the implementation team?
I implemented it alone.
What was our ROI?
N/A
What's my experience with pricing, setup cost, and licensing?
The licensing was not an issue because it is related to the software part. I'm not really sure about the price, because I think we've gotten a discount as we are partners.
Which other solutions did I evaluate?
Traditional Disk-Based backups
What other advice do I have?
The main consideration for anyone interested in Dell EMC Data Domain is to have a good initial sizing. The planning part at the beginning of the project is the most important.
On a scale of one to ten, I would give Dell EMC PowerProtect Data Domain a nine.

Very fast, simple, and excellent support
Pros and Cons
- "It is very fast as compared to the other competitors. Its simplicity and bit rate are also valuable. It takes less time if we compare it with the old solution that we have."
- "Its management can be improved."
What is our primary use case?
We use it for backup.
What is most valuable?
It is very fast as compared to the other competitors. Its simplicity and bit rate are also valuable. It takes less time if we compare it with the old solution that we have.
What needs improvement?
Its management can be improved.
For how long have I used the solution?
I have been using this solution for five years.
What do I think about the scalability of the solution?
It is scalable. It gives the possibility for extension. You can add to the existing units.
How are customer service and technical support?
They are excellent. We have access to them, and they respond immediately and provide the required solution. Their solutions are valuable and effective.
What's my experience with pricing, setup cost, and licensing?
Its price is reasonable.
What other advice do I have?
I would recommend this solution. I would rate Dell EMC PowerProtect DD an eight out of ten. To be able to rate a solution as ten, one must be very proficient and should know several products to compare them all, which is not true in my case.

Great deduplication, robust hardware, and extremely reliable
Pros and Cons
- "The hardware can operate in high temperatures, in case of any disaster."
- "First-time integrations are difficult in NetWorker. NetWorker software needs to be simplified. It's very complex."
What is our primary use case?
We primarily use the solution for backup purposes.
What is most valuable?
The deduplication on the solution is great. It's elaborate but the companies already understand it.
The hardware can operate in high temperatures, in case of any disaster.
The scalability of the equipment and components of Data Domain are outstanding. We never go without Data Domain if we are talking about backup solutions. We always go with Data Domain.
It's a very reliable and consistent product.
There's no match with any other product. It's outstanding. The performance of the hardware is improving day by day and new models are coming with more scalability.
What needs improvement?
In terms of backup software, NetWorker is a very, very good. However, it is very complex. If you want to export on a NetWorker deployment, usually you need to add more plug-ins. If you install Titanium, through the vCenter, you can directly backup all virtualized data. Using Titanium, you can backup Oracle data through the main directly or on the data lake.
First-time integrations are difficult in NetWorker. NetWorker software needs to be simplified. It's very complex.
The technical support has gotten worse as of late. They could work to make it much better.
One feature which IBM has, and which I am unable to see in Data Domain (or on their optimum roadmap) is the utility-based backup solutions. There are no utility-based Data Domain models.
For how long have I used the solution?
We've been using the solution for more than five years now.
What do I think about the stability of the solution?
The solution is extremely stable. You just need to install it and then you can basically forget it. Our users have never complained about the performance and never complained about the consistency or reliability. There aren't any bugs or glitches at all. It's a very solid product.
What do I think about the scalability of the solution?
The scalability is excellent and continues to improve with each new release. That said, a company needs to buy assuming a future scale, as it is physical hardware. If you only buy four terabytes, it's hard to just jump to 16.
How are customer service and technical support?
In terms of support, Dell EMC support was outstanding. Right now, we've observed some changes in support. It's not as good. Whenever a log is up, we do not get immediate support. This has happened a number of times now. If I don't have a senior system engineer available at my company, and I have a server issue, or a backup suddenly stops due to some application restriction, I have problems. I've had a few incidents just this year, the year.
While the support is excellent, the experience of some delays is off-putting. From 2015 until now, we didn't really experience any type of support issues. The delays are kind-of new. Support is perhaps limited in our region. However, beyond the delays we experience, the service we get, and the advice, is excellent.
Which solution did I use previously and why did I switch?
Banks will often have Lenovo or IBM. I always prefer, and my company always prefers, Data Domain. It's scalable and robust and far superior.
We've used Avamar as a backup software. However, we find Networker has more features.
What's my experience with pricing, setup cost, and licensing?
The price point is high. That said, they're competing with other products like Veritas, so in that sense, the price is good, or, maybe typical. And yet, whenever we are competing with some legacy type of product, the price difference is huge.
It's a premium product and so the pricing is somewhat expected.
In terms of scaling, the price is difficult to pin down. IF you buy 4 terabytes, it's not so easy to upgrade to 16. YOu cannot add shells. So users should scale up, to avoid hitting limits down the road. The standard of Data Domain is typically 32 terabytes in terms of sizing.
What other advice do I have?
We are doing multiple POCs right now. We have already installed it in the banks of Pakistan. We are providing solution architects, support, deployment, and residential services.
In early deployments you need to size the backup solution properly and then design it, create it, and export it. Early on, we are sure to always have a delivery of that statement. After delivery, my engineers will be aligned with the Dell EMC CPU, who makes the PDQ chain. That way, we can always patch the required IPs and do those backups as well.
We always deploy the bank's backup software, and we'll do the patches for every requirement. Sometimes we use NetWorker and Avamar. We've deployed Data Domain using Veeam as well.
We always do on-premises deployments, which are mandatory in our country. In Pakistan, you can't have any cloud-based deployments. Compliance and government rules are slowly changing. In a few years, we may also do cloud deployments as well.
That said, wherever we deploy Data Domain virtualization, it is a step towards cloud-based deployment as it's a virtual machine. You can always send the data from a virtual machine to any cloud, including Microsoft Azure, IBM, and ECS.
If a company is looking for an implementation partner, it's best to go with a tier-one partner - someone who is Gold, Silver, or Titanium. They will understand the product fully.
I'd rate the solution ten out of ten. There's no comparison between Data Domain and any other partner. It's solid and consistent. We'll continue to use them. They are excellent.

Good performance, stable, and responsive technical support
Pros and Cons
- "The most valuable feature is the performance because you can back up data really quickly."
- "I would like to see better integration and support for backing up to cloud providers such as Alibaba Cloud."
What is our primary use case?
We are a solution provider and we use the Dell EMC PowerProtect DD to provide service for our clients. It is used to provide backups for VMware environments.
What is most valuable?
The most valuable feature is the performance because you can back up data really quickly.
What needs improvement?
I would like to see better integration and support for backing up to cloud providers such as Alibaba Cloud.
In the next release, they need some monitoring, not only of the backup but monitoring of the firmware and the applications.
For how long have I used the solution?
I have been using this product for one year.
What do I think about the stability of the solution?
This solution is stable and I would rate the stability a nine out of ten.
What do I think about the scalability of the solution?
It's a scalable product.
I have a team of two that maintains it.
How are customer service and technical support?
The technical support is okay. We opened a case and the response was good. We did not have any issues.
Which solution did I use previously and why did I switch?
Previously, we deployed Commvault HyperScale and the Veritas NetBackup Appliance, but the performance is better with Dell EMC PowerProtect DD.
How was the initial setup?
The initial setup was a little bit complex after the initial configuration when we tried to integrate it with the firmware.
It took one week for the deployment, configuration, initializing the backup, and monitoring of the backup for one round.
What other advice do I have?
In summary, this is a good backup product and we are happy with the performance.
I would recommend this product to customers. I think that it has better performance than Commvault HyperScale.
I would rate this solution a nine out of ten.

Reliable solution that reduces the time and effort required to manage the system
Pros and Cons
- "This is a superior and reliable backup system that can handle large capacities with little management."
- "The product lacks some security features that would make it more stand-alone and integrated."
What is our primary use case?
We primarily used this product as a solution for backups.
How has it helped my organization?
This product improved our system of backup by reducing the time and effort required to manage the system.
What is most valuable?
The reliability of Data Domain was the most useful feature to me. Every piece of data is recorded multiple times in several devices in a cluster. If any hardware failure occurs, it does not impact the data and does not result in any data loss. Resilience and reliability under any circumstances are important to data security.
What needs improvement?
Spanning the time I worked with EMC Data Domain, I had no issues that suggested to me that it needed improvement. It was working fine, and anything I wanted to do with Data Domain, I could do it. So I had no idea that it might have needed improvement. That is just thinking from a technical perspective as a user. It did what it needed to do for backup.
In hindsight, I am aware that there is a feature that does not exist in Data Domain related to the security of the product and the data. A friend who works in another organization had a problem when his organization was infected with ransomware. The ransomware locked up the data in the Data Domain and disrupted the data system asking for something in return or it would delete all the data. The ransom was not submitted and the hack successfully deleted all the data. This is a big concern and no small issue where data is critical.
So I believe security measures are not strict enough in Data Domain. I would like to see something in place for better security.
In addition to this — which is related to security as well — there are regulations from the central bank that mandates that we need to keep backup copies that are not connected to the network. They must be completely isolated from the network. Data Domain does not have any arrangements to satisfy this requirement. For compliance, we need to use a secondary solution.
The only other issue is that the prices seem high in comparison to other products and they should consider restructuring their pricing plans.
For how long have I used the solution?
We have been using the product for three years.
What do I think about the stability of the solution?
It's very stable and reliable. I have never had an issue with stability.
What do I think about the scalability of the solution?
This is a very scalable solution. Whenever we needed to we could add new nodes with minimal effort and keep the same data structure.
Defining the number of users for the system is a little tricky because only the backup administrators actually use the Data Domain solution to do the backup procedures for the whole bank as a company. So the actual number of users of the product — hands-on — is around three people. But these three people are doing backups for many systems that are centrally connected to Data Domain. These many systems have around 300 total servers which go through the backup process. Each one of those 300 servers contains data from many users and transactions. In a way, our implementation of this product is serving many thousands of customers, and it can serve many thousands more.
So, yes, I think it is very scalable.
How are customer service and technical support?
Our experience with customer and technical support has been very good. For example, in one instance we had a problem with the hardware and technical support guy came and replaced the failed component. This was seamless from our operations because the system is highly available and redundant. So everything continued working even with some part failing. But the technical support people were knowledgeable, quick and on-premises.
Which solution did I use previously and why did I switch?
Before using Data Domain, I was using a tape library. It was IBM Tape Library with LTO (Linear Tape-Open). We switched to EMC Data Domain because of the speed. Backing up data to a tape library is much, much slower than backup to Data Domain, which is based on hard disks. it's much faster in backup.
The system we switched to is actually EMC Data Domain as the hardware device for backup, while Veritas is the software backup. Veritas has its own hardware device. However, EMC Data Domain hardware is much better than Veritas. The golden combination as I see it is EMC Data Domain hardware with Veritas software. Going that way, I get the best of each in our backup solution.
How was the initial setup?
The initial setup is straightforward. For the deployment, it took one day for the hardware implementation and a couple of days for integration with the software. For several days, I worked with IBM TSM (Tivoli Storage Manager) or Veritas. All of the parts came together well and I had no real issues.
What about the implementation team?
The implementation was carried out by my team and myself with some input from EMC as well. That was a team was a total of two persons from EMC, one person from my team and myself. I just managed the team and oversaw the process. I think normally that a technical team of about three people can handle the deployment.
What was our ROI?
As far as having a return on investment, I see investing in Data Domain as having a positive return. It is reliable and it does a very good job when it comes to data compression and deduplication. It makes the backup size much smaller, which saves the company a lot of money because you are not buying tape cartridges for the tape library or even hard discs for temporary backup to store redundant information.
Another ROI which is less tangible is the time for recovery. If I have a problem and I would like to recover something, it is a much faster procedure working with hardware than with tape.
What's my experience with pricing, setup cost, and licensing?
One thing that anyone considering this solution has to realize is that it is expensive. It is expensive for a reason, but it is expensive.
What other advice do I have?
Anyone considering using this solution will first need to make a proper assessment of their need for the data storage because this is misleading. Sometimes managers just make a simple assumption that an organization has about 50 terabytes of data and that they don't need more than this for backup. This is not correct.
If you look into the whole backup strategy, you will see how frequently you will do backups, how many copies we will need to retain, and the period of days that the data is retained — It will be a specific period of days and the backups will rotate. There should be a retention strategy and a rate of change of the data backups. All of these are parameters that affect the sizing of the data domain device. It could be many times the initial size depending on the strategy and how critical the data is. So assessing the proper sizing is very important and key for the success of the backup strategy.
It is important, as well, to assure that the software and the hardware work seamlessly together because you can mix and match software and hardware solutions to come to the ultimate package. Making sure that every feature in the software would work with the hardware is really imperative before making any decision.
On a scale from one to ten with one being the worst and ten being the best, I would rate EMC Data Domain as 7.5. The reason why it is not higher than 7.5 is mostly because of the cost. It is a very expensive solution. The lack of better security features to protect the data is really another big issue.

A secure backup solution that is easy to use and very simple to implement
Pros and Cons
- "The backup is very secure. The deduplication using EMC is very good. We are able to make systems and handle random cloning. EMC is a very stable solution for making backups."
- "They should reduce the CPC cost to customers. The product is becoming very expensive."
What is most valuable?
The backup is very secure. The deduplication using EMC is very good. We are able to make systems and handle random cloning. EMC is a very stable solution for making backups.
What needs improvement?
The solution needs to improve its platform, especially backup features like DB2 and other system backups.
They should reduce the CPC cost to customers. The product is becoming very expensive.
In the next release, EMC should support stable level listings at restoration and stable space level in the database. Sometimes if I want to take the stable level restoration, EMC is not available. Only this one part is lacking in the current version.
For how long have I used the solution?
I've been using the solution for four to five years.
What do I think about the stability of the solution?
The solution is very stable.
What do I think about the scalability of the solution?
The solution is easy to scale. We have nine people on it and they are all system admins. We are planning to increase usage and to increase the license.
How are customer service and technical support?
Technical support is excellent. I would rate it eight out of ten.
Which solution did I use previously and why did I switch?
We previously used HP Data Protector. The HP Data Protector backup was not secure. We used to do a backup, but at the time of restoration, it would give us some issues on the restored data. We were not able to access and stream data on HP. EMC is much easier in terms of restoring the backup properly.
How was the initial setup?
The initial setup is very easy. Any person can handle the initial setup of the solution.
What about the implementation team?
I handled the implementation myself.
What other advice do I have?
I would recommend the solution. I'd rate them nine out of ten.
