Zerto, a Hewlett Packard Enterprise company, aims to enable customers to run an always-on business by simplifying the protection,
recovery, and mobility of on-premises and cloud applications. Zerto’s cloud
data management and protection platform is designed to eliminate the risks and complexity of
modernization and cloud adoption across private, public, and hybrid
deployments. The software-only platform uses continuous data protection
at scale to converge disaster recovery, backup, and data…
The upside to Avamar versus Veeam is that Avamar has a machine tied to the software. Veeam is good software but it is only as good as the back-end storage.
We initially purchased RecoverPoint and after stumbling through the installation with the consultant and realizing how clumsy and nonautomated it was we began looking elsewhere. We really disliked the amount of setup and manual configuration needed to get basic things …
We use VMware vSphere Replication as our disaster recovery tool for our Tier 2/3 systems. This was chosen as it saves us costs for our less critical, but still needed systems that keep our company running. Putting everything on Zerto would be great, but with this combination, …
This software is well suited for companies that want to be very in control of their backups but need a simple tool. It could be convenient for them to just buy their own node, locate it in a different location, and set up the jobs for their machines to backup to the cloud with the specific plugins. However, it would not be convenient for companies looking to have a tool that needs to be secure and compliant, and that need to have different other options for business continuity.
Zerto is well suited for disaster recovery and virtual machine replication between multiple data centers. DR testing for audit or regulations is much easier with Zerto, great reporting, dashboard etc. It is not well suited for physical server replication for disaster recovery or as a primary backup solution.
Avamar performs data deduplication on the remote host. This greatly reduces the amount of traffic that each backup requires. This even applies to the virtual environment through change block tracking. Backup times are reduced from hours to minutes.
The management interface makes it easy to configure and maintain data retention periods. Many times certain data must be kept for an extended period of time. There is a specific menu for managing retention periods.
The system is able to recover itself from a hard failure with virtually no loss of backups. There is a checkpoint taken each day that provides a recovery point in the event of a catastrophic failure. Since this is a node based system, the loss of more than one node could require a recovery be performed.
While another grid must be purchased, the replication utility allows all backups to be replicated to another grid at a remote location. This ensures the resilience of the backups in the event there is the loss of the primary data center.
Also works on HCI devices performing image-level backups as in our primary data center environment
There is also now an All-in-One appliance for smaller locations
Anyone with a large disk (VMDK) knows the issues of VMware snapshots. Most backup software is a "point in time backup" that uses snapshots. While the backup can be run multiple times per day the stress of the snapshot on the host and storage is eliminated by the continuous protection of Zerto log replication.
A client had a the disks on a VM go missing for some reason. We had them "flip the switch" for a real fail over and press the fail over button. The VM on our DR site started to come alive as the VM at the customer site was brought down. When the DR VM was fully up, automatic reverse replication started. The DR machine was available in a few minutes (to take into account different host hardware) for access. One the vm at both sites were in sync, we had the customer again repeat the fail over process and the DR site VM was turned off and the Production site VM was brought back on line. This was a 200 GB VM and the whole process was finished in about 3 hours.
Zerto also allows for "Test" fail overs that can be configured on many different functions, such as host, datastore, network and IP usage. Configuring the IPs is crucial to avoid inadvertent site cross contamination of the same VM.
Zerto can also retrieve files from any VM disk on the DR site without starting a VM. Very handy for retrieving files or directories.
Since Zerto is running continuous log replication, changes on the production VM are nearly instantaneously copied to the DR site. As with any data process, having sufficient bandwidth for "churn" peaks minimizes the delay in updating the DR site.
The client interface has constant JAVA issues and can be slow and chunky. We have often had issues with current versions of JAVA breaking it so it will not even run.
The backup clients are split out for function. Although this makes them light, it also makes it cumbersome to upgrade clients. The naming scheme can also be confusing for the clients.
I have been using the product for over five years. This has performed so well that with the current system reaching its End-of-Life with EMC next year, I have proposed replacing it with the latest version of the product. Now that it integrates with Data Domain, the cost has been greatly reduced. Instead of the need to purchase many nodes, one Data Domain can replace them creating a significant cost savings.
We really like the easy setup of this replication solution, as well as the ease of management. Not to mention, our internal IT Economist determined that the Zerto solution would provide the best ROI out of the competing solutions we analyzed. So far, his calculations have been spot on, and we have saved substantially
The system overall is easy to monitor and see your backup/restore status. The user interface could use updating as it relies on Java and any updates to Java cause the interface to stop working need to be reinstalled
Usability was the primary reason we purchased the software in the first place. We had compared it to several other software products in the same area, and it was by far the easiest to set up and use. Long-term maintenance proved to be similar, with updates driven by updates to VMware and vSphere, rather than the product itself.
Support is very convincing, always eager to solve issues from the root rather than workaround, don't hesitate to take webex, describe the issues to the core and recommend configuration to avoid further issues. We can ask few questions other than the main issue. They don't hesitate to answer.
Overall support is very good. We sometimes get pushback when asking Level 1 support to escalate to Level 2. This causes undue frustrations when you need a more knowledgeable support person to get involved. We've had to escalate to account reps a few times for this scenario. Zerto is very responsive and normally handles our requests very quickly.
Avamar has simplied the back up approach in their VE edition and is much easier to use than Data Protector. Backing up multiple VMs takes minutes instead of hours now. Creating policies, retentions, and schedules, is vastly improved and much easier.
We started out using Backup Exec which was in service until we virtualized our environment where it didn't perform as well at the time. Then we switched to Veeam which worked well, but then as we started needing to do migrations and off-site DR, we found ourselves relying on Zerto more often.
For my organization, the pricing model was an upfront investment for the Zerto licenses. My organization prefers to pay upfront and not deal with month-to-month or year-to-year pricing models that most companies are moving to. But for some, the investment may be more than they can afford, and would prefer the year-to-year pricing model.
I mean, it was 6 years ago, but we were up and going with all applications synchronizing in short order. The longest tasks was getting the 30 TB of application data synchronized between the datacenters.
Zerto is like having the best possible insurance ... it just works, and often provides the backups taken overnight that are key in recovering data/work between overnight backups.
Zerto easily enabled the move of primary datacenters by allowing easy failover to a secondary site, and failback to the primary site.
