Reviews (1-17 of 17)
- The ability to replicate only delta changes enables us to replicate nearly 200 servers with minimal bandwidth usage and so reduces excessive network costs.
- Being licensed to replicate multiple copies of a server enables us to keep costs down and use a single product for both DR and HA
- Journaling enables simple point in time recovery to cope with user errors that would otherwise require a lengthy restore from backups
- For some servers, the 30-day journaling now replaces traditional backup products, saving cost and enabling speedy recoveries
- I’d like to see improvements to the usage graphs so I could dig deeper into network bandwidth usage with the ability to see what VPG is using most of the bandwidth
- The ability to just failover a single server in a VPG would be useful, as this would reduce the number of VPG that have to be created
- Bulk editing of failover IP addresses would be helpful
- Easy replication that stays in sync when testing
- Easy to upgrade the tool as well as works well in VMWare during upgrades
- Support was able to assist remotely as needed
- Expansion of storage could cause issues at the DR side if not properly expanded before the primary DC
Primary Use Case
Replication of business critical VMware VMs over WAN to the remote disaster recovery datacenter.
The benefits are obvious: The simplicity of the setup and the speed of replication.
The speed of WAN replication is great. It is faster compared to RecoverPoint and 20 VMs replicating over a 20Mbps VPN, which has a RPO less than one minute. Of course, your mileage will vary.
Improvements to My Organization
Compared to the previous DR replication solution, Zerto has decreased both RPO and RTO significantly.
- The simplicity of the setup
- The speed of replication
- Low RPO and RTO
- It's complicated to remove the virtual appliance if for some reason you lose the host.
- Replication of Microsoft/SQL Clusters needs good beforehand planning
Make sure you have enough bandwidth!
- They have a failover testing option which allows for us to check for errors before we do live failover
- During failover there is very little downtime in our environment
- Very good at replicating data over quickly for practically zero loss of data
- The system errors on failover when there is a backup being processed
- Some room for improvement on time it takes to verify data after failover
- 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.
- Zerto is in the process of update their "Offsite Backup" process. This is a scheduled snapshot of a VM that extends the "point in time" beyond the up to 14 days of granular recovery. For those wanting to have a "compliance copy" of a vm (db or exchange or files) this is mechanism that will be improving.
- Zerto is an evolving product that takes user input seriously. They encourage recommended improvements and features from customers.
- One thing Zerto can't do is backup a turned off VM. Many snapshot based backup software products can backup a turned off VM.
- While many backup products are install, create backups and go, Zerto requires a bit of planning on the initial network configuration. Installing the software and configuration is actually easy, setting up a VPN between sites needs planning, particularly for MSPs. Once the VPN is set up the rest is quite easy. This is being addressed.
- It is simple to set up and use. In my opinion, one of the most important functions of a tool is its interface. If you have the best product in the world but it takes an arm and a leg to configure and a doctorate degree to use, then the product isn't worth very much.
- The continuous replication is done very well. The failover and failback process runs smoothly.
- This has less to do with the product than the company, but Zerto as a company really listens to their customer base. We've always had a very good interpersonal experience with their support and sales teams. Having great people behind their product is definitely one of Zerto's strengths.
- The price point and minimum license requirements would make it difficult for a smaller organization to adopt Zerto.
- I'm trying to figure out how to integrate it with SQL, but currently, I've found other DR methods for SQL still work better.
- It's efficient, requiring little resources to operate.
- It's easy to setup and manage.
- It works. We have no issues with it, so it causes no anxiety.
- I haven't found anything I would change with Zerto. Simple and reliable is what is most important, and Zerto is both of those things.
- Support of multiple hypervisors.
- Support of replication to the public cloud.
- Hardware agnostic in regards to storage.
- Would like to see support for KVM.
- More automation.
- More customization of dashboards.
- Simple installation process
- Single pane of glass for administration of replication and protection
- Hypervisor agnostic approach
- Quick updates
- Better support for SQL server high availability. Databases have to be removed from HA prior to upgrades of Zerto software.
- The recovery time objectives can be within seconds and not minutes, thus your data loss is minimal if at all.
- The setup and configuration of Zerto is extremely easy and can be done with little exposure to it beforehand.
- The actual process of doing a failover is a one button click process.
- The ability to do multi-site replication cannot be restricted to a selected few virtual machines. It is an all or nothing approach.
- The minimum amount of virtual machines that you can initially start out with is higher than 5. This would not be feasible for small organizations.
- The license packs for the number of virtual machines that will be replicated are somewhat large and are not ideal for small organizations.
- It is very easy to install.
- The replication is great. The journal based approach gives perfect recovery point options.
- The orchestration helps in case of a disaster to get all applications running again in an orderly way.
- The administration is very self explanatory.
- Zerto needs a lot of open tcp ports between the different components. Especially in a cloud setup this is sometimes cumbersome. Less communications ports would be an improvement.
- To streamline the implementation of a disaster site, it would be great if Zerto could also offer some kind of layer 2 LAN extender to connect recovery site and production LAN.
I do not recommend it to use as the only backup solution. Since Zerto does not use snapshots it can work with other tools like Veeam Backup Reviews without any problems.
- Zerto installs within minutes and depending on replication bandwidth can replicate entire VM's irregardless of size.
- A side benefit to Zerto is the product can retain between 14 and 30 days of backups for use at either production or DR site.
- A feature of Zerto is it uses Hypervisor based replication via existing networks, which translates into no backend storage cycles or capacity wasted on array based replication and no extra networks needing to be created for separation of replication traffic, which speeds up the deployment of the software.
- Zerto allows for a blend of DR related testing including failover/failback and bubble testing, without the need for extra storage capacity for journaling space. Some replication technologies need double and even triple the amount of replicated capacity to perform any testing.
- Zerto is great for it's uses cases and has no real areas for improvement. It's GUI and internals are excellently worded to allow for ease of use. It's backup section is superbly orchestrated.
- Zerto is extremely easy to manage and use vs. other hardware solutions like EMC RecoverPoint, which we tried in the past.
- Zerto replicates on the hypervisor layer, which in turn replications the entire VMs, which lessens the complexity of having to replicate both data AND VM. it does both.
- It's storage agnostic, so you don't have to have the same storage in both prod and DR environments.
- It would be nice to have a shorter window of consistency checking when you failover. It takes a long time when you have a larger VM that you have failed over.
- The integrated backup solution is a little convoluted and weak vs. other products like veeam, and should be strengthened for wider acceptance.
- Cross Hypervisor replication. If you have VMware on one site, and Hyper-V on another for cost savings...you can easily replicate from one to another.
- In the latest version 4.5, you can now recover any file, folder or application from Zerto.
- Ease of set up. Install software -> Configure hosts-> set up ZVM-> set up VPG and begin replicating.
- Easily test fail over with a click of a button.
- If you have high iops or lots of changes happening in a VM, then replicating those changes over the WAN from ipsec vpn might take some time.
- Hyper-visor replication only. But very good at it.
