Datto is a fantastic option for smaller businesses who don't have as large of a budget. It might work well for larger businesses as well, but the features are not exactly on par with more prevalent backup solutions. So, that should be kept in mind while determining a good fit for a company. But if selling a backup solution is met with push back, this can be a great option to give a good working backup solution. It offers the main features solutions should have, so it's definitely not a compromise. Just keep in mind the features it does not offer.

Zerto
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.

Pros
Kaseya
  • Simple agent setup for new machines to be protected. A new machine can be setup on the server in under a minute whether it be a Linux or Windows based machine.
  • Local virtualization on the Datto is quick to start up. After a physical problem with a server I had the machine locally virtualized on the Datto before users had a chance to report service issues to me.
  • Nothing to do on my end to get backups shifted to offsite data center. Schedules are setup for each machine or group of machines and I sleep well knowing all our backups are safely stored offsite.

  • 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.

Cons
Kaseya
  • Initial backup sync: The downside to the cloud backup is that, if you have a lot of data, you need an external hard drive to seed to the cloud. And you usually have to request this after you've already got everything else working.
  • Unsyncing: We have pretty decent bandwidth, but with 8TB of data, we'd get syncing issues with the cloud servers every 3 months or so. The only way to address it was to request another external drive and resync it, but that also meant losing the older data.
  • Availability and support: Datto only operates through MSPs and VARs, and will not help you directly without putting in a ticket with your provider. This causes delays, and extra epenses, and if you grow beyond the need for an MSP, you have to keep them around for at least that piece.

  • Moving a VM from one protection group to another could be simplified.
  • I would like to see an executive-style report of recovery and testing for upper management.
  • The ability to deploy Zerto as a virtual appliance, without the need for a windows server.

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

Usability
Kaseya
Usability is great. The web interface is simple and easy to use. While various options are available for client backups, it is very easy to re-use settings of the existing client, so adding new clients is a very fast process. Configuration of the agent on the client-side cannot be easier as well. Datto dashboard provides an overview of the client status, and email notifications can be configured for various events.

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 Rating
Kaseya
My specific example or reason for this rating goes back to a need for support after a client on this platform has a fire. In a nutshell, Datto had no idea how to BMR the image back to the server correctly, and as a result, the RAID on the server was lost, due to the Datto BDR environment not being able to see the RAID card, and the support technician knowing how to inject drivers.

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.

Make sure the end goal is in mind before implementing. That way results meet expectations.

Datto seemed to be better than other vendors I trialed, and I inherited an Alto device, so it was easy to stay with them. I also assumed the backups had been working with the previous contractor, but it turns out they had been failing for months and no one knew it.

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.

Return on Investment
Kaseya
  • In most cases, Datto will provide the appliance free of charge with a 3-5 year contract which results in a modest monthly fee instead of a large initial outlay and monthly fees.
  • The contract's warranty is top-notch. Failed drives or issues with the appliances are replaced/corrected with free replacements and shipping.

  • 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.
