RE: [Dump-users] dump and snapshot

[Andrew L. <an...@me...>]

Have you looked at logical volume management solutions capable of creating
snapshots, such as LVM for Linux or IBM's EVMS (Enterprise Volume
Management System)?  I've been using EVMS (highly recommended, see
http://evms.sourceforge.net/ ) for a while now, and found it pretty
straightforward to script the creation of snapshots for dump backups.  It
seems to me that creating snapshots is more a function of the filesystem,
or lower-level storage drivers, than it is of the backup application
itself -- I'm not familiar with vfsdump, which you mentioned earlier, but
I'm guessing that if it can do snapshots, it's tapping into a fundamental
ability of the filesystem, rather than doing all the work within the dump
program itself.
