[SOLVED] What's the best and cost effective way to backup VMs?

[Razva]

Hey,

Right now I'm backing up VMs via PVE's default Backup function on an external/off-site CIFS. Works great, but it's slow and it's very "space inefficient". For example a single 50 GB VM that's backed up daily for 7 days takes 350 GB.

Are there any better alternatives out there? Maybe something incremental?

Thanks!

Veeam agent (free and has to be installed on each machine to be backed up) which can be centrally managed by Veeam Backup & Replication (also free for up to 10 machines/agents).

Set and forget, it just works.

P.S.: one of our SQL-Server-VM with about 80 GB in total just takes arount 1-3 GB incremental upates per day

Thanks for the suggestion, but I'm looking for something that doesn't needs to be installed on each machine/VM, as not all VMs are managed by us.

With ZFS you can do incremental. I think this is most efficient. And if you have enough memory you can turn on dedub, and save fullVM-Backups also incremental.

Coud not find a HowTo, can you please explain it in detail?

Yeah, the problem with this kind of setup is that there's no incremental backup. Basically you backup a full dump of all VMs, which is what I would like to avoid.
