Hi,
I have two identical systems, one of which serves as a cold standby, should the primary ever run into problems or to check system updates for side effects.
Now I have already tested that I can put the system into suspend mode (S3) with
and start itup from mybackup system using
I would like to automatically backup this stand-by system as well and start it up with WOL shortly before the backup starts and then suspend it again.
During my tests I had all containers and vms shut down.
Could I leave them running?
Or is there any reason to suspend them first before suspending the host?
I would prefer to just suspend the host and trust that everything will come back without issues.
Occasionally I ran into problems when doing that on desktop systems with running VMs, but I suspect that was mainly the graphical interface.
Any opinions/suggestions?
Kind regards,
z.
