FreeBSD's softupdates should make filesystem state always consistent,

Freebsd's dump -L (live option) uses ufs2 snapshot capability to ensure
consistency, so its dump is reasonably smart. (FWIW / on Freebsd usually
does not have softupdates specified, so usually won't help here). So
yeah, it looks like some care is needed with plain old 'dump' on Linux -
which is a bit of a pest!
I use rdiff-backup for my backups but then again I have low requirements
wrt. consistency outside file-level. I have considered LVM snapshots
since I use LVM already but havent bothered so far.
Right - what you intend the backup to protect against drives all this
sort of stuff.
