[PVE-User] Excluding individual vdisks from PVE backups?

[PVE-User] Excluding individual vdisks from PVE backups?

[Frank Thommen]

Dear all,

we are doing daily backups of every VM in our PVE cluster to the 
internal Ceph storage (snapshot mode, ZSTD compression).  However one of 
the VMs takes six to seven hours for the backup, which is unbearable and 
also interferes with other backup processes.  The delay is probably due 
to a 50% filled 500G vdisk attached to the VM.  Is there a way to 
exclude this specific vdisk from the PVE backup schedule, while still 
retaining the rest of the VM in the backup?

We don't have PBS in place and will not have it in the near future for 
different reasons. So PBS would not be an option for us.

Cheers, Frank

hi Frank
you can exclude CT/QM or some path see details at man
# man vzdump

example
via webGUI
   cluster > backup > edit > selection > ... exclude some VM ...
via CLI
   0 2 * * 6	root	vzdump --exclude 104 --mode snapshot --quiet 1 
--maxfiles 1 --storage backup --compress lzo --mailnotification always 
--mailto admin@some.where

best regards
Nada

Thanks a lot for the hint.  I should probably look more often into the 
advanced configuration settings :-)

Hi Nada,

thanks, but this would exclude the complete VM from the backup (we have 
that for a few special VMs).  However we wanted to exclude only one 
specific vdisk of a specific VM and not the VM itself.

I have implemented Eneko's suggestion (see the previous mail in this 
thread).

Cheers, Frank

Just as a final confirmation: Your suggestion worked like a charm.  The 
backup time came down from >6 hours to 8 minutes :-).

Thanks again
Frank
