However, this is not necessarily the preferred backup method since data potentially has to travel twice across the network (NAS to backup client and backup client to backup server).
If you are using NDMP (Network Data Management Protocol) based backups, which are available with the latest release of the Guardian OS, it is now possible to take NDMP "hot backups", where data is backed up while remaining accessible to the users. In fact, the WorkGroup Edition of BakBone's NetVault software is integrated into the GuardianOS v3 used by Snap Server, which enables online backups.
