We performed a comparison between Hornetsecurity Altaro VM Backup and Zerto based on real PeerSpot user reviews.
Find out what your peers are saying about Veeam Software, Zerto, Commvault and others in Backup and Recovery."Ability to restore to any host."
"Excellent compression and deduplication with off-site WAN backup included."
"Reverse Delta is Altaro proprietary backup deduplication technology. With Reverse Delta, the latest version of a file is always made available in its entirety, not as a delta file."
"Valuable features for us include quick recovery, compression, and deduplication."
"The interface is user-friendly and even if our tech isn't onsite, we can work with the owners to confirm that the data will be restored with no issues."
"The product has many valuable features for handling backup needs, including replication, live migration, and incremental disaster recovery."
"The ability to test the backups without having to manually mount the VHDs after restore allows us to check the integrity of the backups."
"It is an excellent product. It is easy to deploy, stable, and fast. Their support is excellent."
"It is incredibly granular and I really appreciate that."
"I like the less than one-minute RPO, the ability to IP customize during failovers, and the cloning feature that I can use to clone VMs over at the target location. As part of the automation failover, if we need to change an IP when it fails over to the other data center, Zerto will handle that; there's no need for manual intervention. As far as the cloning, we use that to do quick testing of a VM in the remote data center for lift-and-shift processors."
"Zerto's continuous data protection is unmatched. It's phenomenal. It's also very easy to use. The menus are self-explanatory. Once you understand the terminology of the product, what the VPGs (Virtual Protected Groups) are, you're able to pretty much do what you want in the product. It's very easy to use."
"I like the fact that Zerto is target agnostic. It doesn't care what type of storage it writes to. The journaling is also excellent. You can easily and quickly restore to seconds before an event. The immutable data copies feature is one reason we adopted Zerto. That's one of its selling points."
"We have seen ROI. The biggest way that we have seen it is in avoided downtime. We have had outages before, and we count downtime in terms of dollars spent. We have cut that down so dramatically, which provides us a very quick ROI. We have drastically reduced the amount of time it takes us to recover workloads, from an average of two hours to an average of 10 minutes."
"The stability is great; there's very little downtime. I don't have to worry that there will be a surprise update to one of the ZVRAs or the host that I have to contend with. We're given plenty of notice to plan ahead for an update. As far as losing service and downtime, we haven't had that happen."
"Since we are at a bank, there are certain protocols in place where we need to have RPO and RTO times of two hours or less. Zerto does a great job of setting those times and alerting us if those can't be met. We have our help desk actively monitoring that. It is extremely helpful that Zerto lists what is falling out of compliance in regards to RPO and RTO. It has been great in that regard."
"Continuous replication is the primary feature we use now because we originally purchased Zerto. I'm starting to utilize the long-term retention and instantaneous file restoration features, which have been introduced since the original purchase in 2015. Initially, we deployed Zerto as a second data storage point, but ultimately it will probably facilitate some of the migration of my workloads up to the cloud. It's evolving with the network and how we deliver computation."
"The initial set up was complex, and I was not able to do the set up myself."
"The cloud backup and VMware support (now available in the latest releases), could do with some improvement."
"It would be nice to be able to recover the items to their original location."
"To improve Altaro, I would like to see the ability to choose more than one backup location at a time."
"Backup speed and comparisons between versions used to be slow on big VMs but that was improved greatly later on."
"The application could include a feature to install a set size of data, such as the ability to store a single application with all its registry information for easy transfer."
"It would be nice to see a feature that backs up the host so that, in case of a server failure, an entire server could be restored all at once."
"Availability of physical server backup would be an added advantage."
"The product could benefit from improvements in automation, specifically in the area of failovers."
"Increased granularity in how long to keep the journal would be nice."
"When we do failover and failback, it doesn't maintain some of the settings that it should and I don't really understand why that happens."
"The number-one area in which they need to improve their product is what I would call "automatic self-healing." This is related to running them at scale... We have 1,000 VRAs and if any one of their VRAs has a problem, goes offline, all of the customer protection groups and all of the customers that are tied to that VRA are not replicating at all. That means the RPO is slipping until somebody makes a manual effort to fix the issue. It has become a full-time job at my company for somebody to keep Zerto running all the time, everywhere, and to keep all the customers up and going."
"The full site recovery is not up to SRM standards."
"I would like to see a couple of details regarding awareness of VM events coming outside of ZVR."
"Certain areas were designed and work fine for VMware but are under development for Hyper-V. Eventually, all features will work for both platforms."
"In Azure... We have to make sure that every resource group is tagged correctly, with the correct team and department because we have to bill them at the end of the month. The problem is that Zerto does not have that ability. When the product fails over or migrates a VM from on-prem, or even within Azure, to another site, it does not give you the option of selecting an existing resource group."
