Carbonite Availability Formerly DoubleTake vs Zerto

• A product is worthless in my opinion if you don't have a great support team to work with. I've had issues with replication jobs that were resolved quickly and easily by the support team.
• DR - Doubletake is the only tool that I'm aware of that can handle DR replication of both physical and virtual environments. There sre others, but they use a snapshot technology, where doubletake has continuous replication of data.
• Move - we have moved physical and virtual environments from around the world without ever having to leave the office. One of the companies we migrated started off with their equipment in Switzerland, and after the servers were in a fully protected state in the US, that failover to the new location took 45 min.

• 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.

• More verbose error messages. So we can fix problems with more ease
• More bandwidth settings for throttling.
• Ability to restart services on servers from the double take console

• 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.

• It has allowed us through DR testing to meet contractual requirements of our major accounts..
• It gives us peace of mind that in the event of a major issue we can perform our daily business with a relative success rate.

• 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.
