Lots of options. - The standard backup technique is dump(8)/restore(8). It takes more than an hour for me to get back up from a dead disk, but I think it would be much faster if I didn't encrypt my backups. [Also, size and speed of disks and backup media will matter, of course.] - There are "ghost" style programs that understand BSD filesystems. I don't really see any advantage to these. - mirroring techniques. This would mean that when a disk dies, you already have a copy of it ready to step in. Some forms of RAID will do this for you, there's a GEOM class that will mirror any filesystem on it, or you could run a separate program (e.g., rsync to copy changed files over on a schedule). Other than, possibly, the "ghost" options, you'll find more information on all of these concepts and terms in the FreeBSD Handbook. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
