Re: [ovirt-users] looking for some ISV backup software which integrates the backup API
Nathanaël,
I can share my backup experience. The current backup/restore api integration is not
optimal for incremental backups. It's ok to read the whole disk if you backup it first
time, but you have to read the whole disk each time to find changes for incremental
backups. It creates huge disk load.
For optimal backups it's necessary to keep a list of changed blocks since previous
backup.
See http://wiki.qemu.org/Features/IncrementalBackup
Since it's not implemented in oVirt the best option is to run a backup agent inside
VM. Yes, it's not very convenient, but it's necessary yet.

Hello,
We are about to change our backup provider, and I find it is a great
chance to choose a full supported ovirt backup solution.
I currently use this python script vm-backup-scheduler
(https://github.com/wefixit-AT/oVirtBackup) but it is not the workflow
officially suggested by the community
(https://www.ovirt.org/develop/release-management/features/storage/backup-...).
I've been looking for a long time an ISV who supports such an API, but
the only one I found is this one :
Acronis Backup Advanced suggested here
https://access.redhat.com/ecosystem/search/#/ecosystem/Red%20Hat%20Enterp...
I ran the trial version, but it doesn't seem to do better than the
vm-backup-scheduler script, and it doesn't seem to use the backup API
(attach a clone as a disk to an existing vm).
Can you suggest me some other ISV solutions, if they ever exist... or
share me your backup experience?
