vzdump --snapshot shows "INFO: backup mode: stop"

See also the follwoing output

[root@myserver ~]# vzdump --snapshot 101 --tmpdir /tmp --dumpdir /root
INFO: starting new backup job: vzdump --snapshot 101 --tmpdir /tmp --dumpdir /root
INFO: Starting Backup of VM 101 (openvz)
INFO: CTID 101 exist unmounted down
INFO: status = CTID 101 exist unmounted down
INFO: backup mode: stop

I hope it is bug, but my guess is that vzdump switches to "stop mode" because the container is stopped already?

But why? If I want to do a 100% clean backup by shutting down the container first, wouldn't it be still useful (and fast) to use the snapshot mode. This way the container could be started again very quickly.

But why?

It uses less resources (no snapshot).

 

[proxymoxy]

Understand, but if a user uses the option snapshot (and not stop), then it should run in snapshot mode. I think if the user uses the snapshot mode the user aware of the additional disk space requirement.

Would it be possible to add an option for this in the next version (I guess the only way to keep it backward compatible)

Feel free to send a patch.

 

[proxymoxy]

Ok, will do.
Will try (need to learn about patching first ;-)

Just to make sure I am on the right path. This is basically the only important part in VZDump.pm?

my $mode = $running ? $opts->{mode} : 'stop';

I think I am finished. How should I deliver the patch?
