If you were to make /vz an LVM volume, you could do a snapshot, and grab
those contents with NetVault, tar.gz, etc.
LVM will track the differences (i.e writes) between the two, and the
snapshot is a point in time save of the filesystem.
Normal filesystem activity continues on during the snapshot, so service
is not interrupted.
We're using LVM to provide snapshot backups for the XEN VE's we host.
For /vz, just make sure your LVM disk pool has enough space left over to
take the /vz snapshot.
If it runs out, it will likely abort the snap, or have unexpected results.
You may want to run the testing 2.6.16 ovz kernel, as LVM has some bugs
with older kernel versions.
Cheers!
