My way to backup the backup ;-) is LVM

The pool is on a LVM as a LV. To backup the pool while backuppc is
running I can take a snapshot of the pool's LV and I rsync this one. So
there are no filesystem issues and backuppc can stay running while the
rsync is running.

As the pool is connected to the backuppc through iSCSI the backup runs
on a different host and does not influence any running backuppc tasks.

Works like a champ!
