Its easy to do incremental and encrypted backups to a ftp/ssh/scp
backup space.
Use PVE to make a backup an uncompressed backup,
Create an encrypted gz/lzma backup, delete the uncompressed backup
incremental backup that file to ftp/ssh/scp.
Hi,
As I wrote earlier, I use zfsonlinux for easy, flexible, low resource
hungry solution to send backups to offsite and keep several backups in
place if something goes wrong (messed upgrade of a VM, etc.).
With the stock PVE configuration with local disks I had a nightmare
every night: backup one copy of every VMs/CTs, took 8-9 hours and take
a lot of space.
Now I use zfs-auto-snapshot -> it takes no time to create as
many/frequently "backups" in place, without wasting spaces and time
and I can use daily zfs send/receive to achieve a remote backups.
Again, this solution does not need any resources (high cpu / disk io /
disk space / lvm snapshot / time / rsync / whatever) thanks to the zfs
features.
I did not try but as far as I know, ceph also has live snapshot/self
healing capabilities, so, one who use ceph should do the same,
probably easily.
Afaik GlusterFS is not really good for the same purpose itself, but
using it on top of a ZFS storage and using only mirrors should work
well for off site backup.
Cheers,
IStván
If you don't have zfs, you can try this:

I used it for other purposes, not Proxmox, and it worked well.
