how to set attributes vor virtual drives with qm set

[WRZ]

Dear all,

we have one vm with some crucial data and some nice to have data.
The drives virtio0 + virtio1 contain the crucial data - some 450GB of it. We can afford to loose a day worth of this data but not the entire set.
The drive virtio2 has some 2TB of non-crucial data.
we have a 1Gbit/200Mbit aDSL connection.

The current strategy ist to:

replicate the vm to a twin server every hour
back up the entire 2,5TB every night to a pbs in a different room on site
make s offline copy of the virtio0+1 to an external drive.
unset the backup flag on the virtio2 and run a manual encrypted backup to a pbs off site.

now I would like to make a script to :
unset the backup flag on the virtio2
run vzdump to the off site pbs
set the backup flag on virtio2

can this be done with qm set?

Thank you for your support!
Kind regards
Martin

you can't set a single attribute, just the full config property string.

Thank you,
are there some real life examples for the full string?
Kind regards

you can just use the current one and replace the attribute you want to change..

e.g., qm config XXX
