Scalability Issues

Sentiment score
4.9

Sentiment score
7.5
HPE Zerto Software scales easily across environments, offering adaptability, simple licensing, and robust disaster recovery with minor performance considerations.
You can expand it as much as you can expand it, but if you get the Datto SIRIS 3, it's not going to be as good as the enterprise version of Datto SIRIS 5.
Cyber Security Consultant
The contracts are flexible enough to upgrade or downgrade the product without too much of a penalty.
Managing Director at HB Technologies
Scalability is dependent on the cloud provider we are using, so it cannot be solely judged through Datto SIRIS.

Room For Improvement

Datto SIRIS struggles with Mac OS backup, performance, high costs, and requires faster recovery and better integration tools.
HPE Zerto Software requires better Hyper-V support, pricing, UI enhancements, integration, documentation, automation, and improved backup and alerting systems.
The backup of the Mac OS solution in Datto SIRIS doesn't exist at this moment.
Engineer at a renewables & environment company with 51-200 employees
Saying that it is the network is not detailed enough. We need more specific information about the network.
President & CEO at a tech vendor with 51-200 employees
Strengthening security to enhance the product's overall effectiveness in backup and disaster management.
Infrastructure Engineer at Neurealm
If I have 350 objects that I am protecting, I would like Zerto to be able to fire them up in one order, rather than having to manually bring them up in a sequence.
Enterprise data management supervisor at a insurance company with 1,001-5,000 employees
If the host has a lot of VMs on it, there may not always be enough time to relocate all of the VMs from a protection group standpoint to other hosts before the replication appliance that Zerto uses to manage that powers itself down.
Systems Engineering Manager at a legal firm with 1,001-5,000 employees
If HPE Zerto Software has it built-in where we're going to vCenter and you click on it, it will build the VPG and indicate configuration requirements, that would be amazing.
Senior Converged Infrastructure Engineer at a educational organization with 1,001-5,000 employees
 

Setup Cost

Datto SIRIS offers fair pricing and seamless setup, but lengthy contracts and MSP upcharges might deter some SMB clients.
HPE Zerto Software is seen as a worthwhile investment for enterprise needs despite higher costs than some competitors.
The only issue is that a lot of people are looking to cut costs, especially right now, and Datto has priced itself out of one of the largest parts of the U.S. market.
Cyber Security Consultant
It's a high-level solution, and the price is correct for me.
Engineer at a renewables & environment company with 51-200 employees
Thoughts on pricing indicate that it is handled by a different team, varies based on specific solutions and storage capacities selected by organizations, and is generally fairly priced for the value provided.
Infrastructure Engineer at Neurealm
If you want a good-quality tool that is robust and does a good job for you, you have to pay a higher price to get that, and Zerto is no different.
IT Manager at American Pioneer Federal Credit Union
However, it can become quite expensive when you start looking at the number of workloads you have in the environment and what you would like to do.
Cloud and Infrastructure Services Manager at a healthcare company with 1,001-5,000 employees
Zerto is easier to set up and use, and it's less expensive.

Infrastructure Engineer at Neurealm
In the last six years, none of my customers faced a ransomware attack, and we use this functionality for system outages and physical server crashes.
System Engineer II at a tech services company with 1,001-5,000 employees
The reporting via email from Datto SIRIS for me, my customer, and my team shows that every single backup is okay or if there is a problem because the snapshot for the server is broken or another problem that I can address systematically.
Engineer at a renewables & environment company with 51-200 employees
Zerto offers excellent technical support with responsive and helpful experts.
Assistant Manager-Networks at a university with 1,001-5,000 employees
If we were attacked, I could revert to a backup from five seconds before the attack, and no one would know we were attacked.
Senior Systems Engineer at a financial services firm with 51-200 employees
The replication time and the minor amount of time it takes to sync a new server outside of any of my huge 40-terabyte boxes is ridiculously quick.
Sr. Systems Engineer at a legal firm with 1,001-5,000 employees

James Melton - PeerSpot reviewer
Cyber Security Consultant
Reliable backups have protected email and servers and now enable rapid ransomware recovery
For the smaller Datto SIRIS devices that are made for backing up one or maybe two different machines, adding more RAM and giving it a better CPU would be phenomenal. Sometimes when dealing with entry-level Datto SIRIS products, you face an issue depending on how much storage there is on there when it's trying to parse through all of the data. It takes a while, and when it comes to data recovery, time is everything. Datto SIRIS should remove the ability to set it up as a NAS-based file share operation system. It seems counterintuitive for something that is made for immutable storage that is walled off so that it can't be destroyed to be allowed to be a local centralized file share that individuals have access to. This seems to be begging for a mishap. Datto SIRIS will require some maintenance when the hard drive gets past 50% capacity, which is Datto's statement on the capacity. You should never use past 50% of the storage locally. Then you have to reach out to Datto directly to get an external hard drive to transfer files to send off the data for it to be shot up to the cloud. We've had a couple of instances of devices not uploading to the cloud because either they were too full or there were failures in certain parts of the file upload to the cloud, which put it into a circle of death where it just kept trying to do the same thing over and over again and had to request assistance from Datto in those situations. Otherwise, if you store it in a dusty cabinet, you have to spray it with a computer duster every once in a while.

Dev Ops Engineer at a media company with 201-500 employees
Near-zero downtime has protected critical workloads and now simplifies hybrid cloud recovery
The best features of HPE Zerto Software are mainly very sophisticated and relevant to the current market. The data protection CDP part has real-time replication, unlike other solutions that have snapshot backups. We can set it up hourly, making it ideal for use with workloads. Another attraction is the near-zero RTO, with automated failover within minutes and one-click failover and failback. Currently, we are using a hybrid cloud solution, and HPE Zerto Software supports multi-cloud environments, making it easy to migrate between on-premises and cloud. Regarding the impact of HPE Zerto Software on our RTOs, we have near-zero RTO, meaning the system must be back online within thirty minutes if we measure the time. It is very quick to recover services. With HPE Zerto Software's near-synchronous replication, we have some CDP protection, so we typically write interceptions along with some asynchronous replication. There is almost real-time replication available.
