We decide to try the backup system option to backup whole virtual server.
"Remote SSH server:"
and to use LVM snapshot if possible.
But after hitting button "Backup now" almost nothing happens we only see:
Finding systems to backup ..
.. found 1 systems
Working out backup destinations ..
.. found 1 usable destinations
And browser stops loading and no new processes on the server - nothing.
Do we need to create LVM snapshot beforehand or we are missing something else.
