But it would be good if they have gfs retention policy. Backup to NAS, USB drives, FTP and Cloud. Open file backup (VSS) and synchronization.

I have no negative comments about Vinchin solution, which works well for us. Creation of recovery disk with Iperius Recovery Environment®. And the instant recovery is trully amazing, I like it very much. But best of all, its customizable backup jobs would do everything it can to save storage and speed the whole process up.

I like the agentless and lan-free backup for there's more reqiurement for agent and that makes things easier. Vinchin has flexible installation options as a physical or virtual machine, the ease of deployment, and reliable backup strategies, all of them make it works really great with Xenserver. And another one we choose it because Vinchin charges reasonably. The recovery unit will contain Iperius Recovery Environment, which is a wizard that will start up when the machine is booted and will allow to perform a bare metal restore of a Iperius drive image, even on different hardware. Bitdetector, node expansion and data deduplication, all these technologies save a lot space and cost for us, not to mention the archive to cloud and offsite backup copy features, they can be strong support against disasters and accidents. Vinchin happens to be the one fits our standards. Comments: We have 100 Xenserver vms run on our environment, given the popularity of Xenserver, it's not difficult to find a reliable backup vendor, but what stumps us is a comprhensive one with resonable price and reasurring protection guarantee.
