[PVE-User] ??utf-8?q? VM Backup best practicesrecommendation...

[Fabrizio Cuseo]

I have your same problem; backup strategy and software is a priority for a lot of vendors; vmware have both backup (with dedup and flexible retention policy) and replication; veeam is a great suite and is a must-have for a more complex and big cluster. 
I know that proxmox is based on community software, and backup (i mean incremental backup) is not simple, but i can't believe that all the users are satisfied with vzdump. 
I personaly miss: 
- a retention policy different from "the last" backups; i know that i can write script to move and rotate some backups, but simplicity is the winner; if i could select in the backup option a "keep last X daily/weekly/monthly/yearly backups", all is simpler and error free 
- an incremental backup; this is really the big miss. I have too long backup windows, so i can't backup the vm every day. And I can't use backuppc/bacula or some other guest-based backup software, when i use proxmox to host vm for customers, 
- backup verification (it can be useful) 

Regarding incremental backups, based on dirty blocks, i don't know if this feature is usable: http://wiki.qemu.org/Features/IncrementalBackup 
But, even if only with some kind of storage backend, we could make incremental backups. Using ceph (that is fully supported by proxmox), is possibile to make incremental (or differential) backups, based on snapshots. I have manually tested with "rbd --export-diff" on ceph snapshots, and works like a charm. So i think that, even if only for ceph storage, it can be developed (zfs solution can be similar) 

No one need to have a better backup support ?
