Hi all,

I'm evaluating oVirt as a replacement for VMware, and one of the factors that I am struggling with is incremental VM backups. This is a requirement in the current configuration, but I haven't found a way to do it with oVirt as yet. It seems from my initial investigation that it might not be possible at this stage?

I refer to the wiki (http://www.ovirt.org/Features/Backup-Restore_API_Integration#Incremental_Virtual_Machine_Backups) which lists this feature under future work, and to a StackOverflow question which remains unanswered (http://stackoverflow.com/questions/29127855/how-to-setup-incremental-backups-on-ovirt).

So my questions are

1) Can anyone confirm whether this feature exists yet, or whether there is perhaps an unofficial way to get incremental backups,

2) If it's not possible to implement incremental backups, what other approaches could work? Under VMware we currently take weekly full backups of all VMs, and daily incremental backups.

I am considering using guest-level backups as an alternative approach, but we would prefer to continue with our host-level backups if possible.

Thanks,

Rudi
