If the snapshots are taken while the fileserver is active, then the=20
partition would need to be salvaged (and fscked first, if the 'inode'=20
fileserver is in use) before it could be used.
As long as no volume create/destroy operations (or the _first_ backup or=20
replication of a volume) were done between the snapshot time and the=20
restore time, no database synchronization will be needed. (if=20
synchronization is needed "vos syncvldb <server> <partition>; vos syncserv=20
<server> <partition>" should be sufficient to fix things up; a restore=20
should not be needed and would cause problems if meta operations were done=20
to a partition that is not being regressed.)
