Dump snapshot of UFS2 filesystem, then gzip it

dump -0Lauf - /dev/adXsYz | gzip > /path/to/adXsYz.dump.gz
Opens a snapshot of a live UFS2 filesystem, runs dump to generate a full filesystem backup which is run through gzip. The filesystem must support snapshots and have a .snap directory in the filesystem root. To restore the backup, one can do zcat /path/to/adXsYz.dump.gz | restore -rf -

What Others Think

Come on, why that gzip? dump is compiled with libgz, so just add the '-z' option

@unixmonkey10432 Dump in FreeBSD takes different options than dump in Linux (compare http://linux.about.com/od/commands/l/blcmdl8_dump.htm with http://www.freebsd.org/cgi/man.cgi?query=dump&sektion=8)
