Point in time recovery allows you to restore you system to a single point in time. Backups, depending on how they're performed, give you multiple points in time from which to recover. > What I want is to have a identical backup drive at > every moment in time.

Keep in mind that dump remembers, via dump levels, what's been backed up so it will do incremental backups. > Geom looks cool, I will start reading the docs and > look into them.

Re: backup existing sata drive
Thanks for your answer. I can mount all the partitions (ubuntu via the mount_ext2fs command). So, I could use DD, but then I would have to do this every time I want to be synchronized. This would be the firts thing I could try, when the disk drive arrives. Then I would know I have at least a copy of the full disk. Hmm, I have to think this over, but nice knowing this is an option. --- "Peter A.

Dump is an excellent solution if you can mount all partitions (see http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/backup-basics.html for details on using dump) DD would be another option that would copy the entire hard drive sector by sector, regardless of the partitions. If you are interested in basically a "mirror" sort of situation without running RAID, dd is what you are looking for. dd doesn't care what the partitions are, indeed you could even backup Microsoft partitions with it. http://www.freebsd.org/cgi/man.cgi?query=dd&apropos=0&sektion=0&manpath=FreeBSD+6.1-RELEASE&format=html basically: dd if=/dev/sourcedisk of=/dev/backupdisk bs=1m ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

With gmirror(8), you can specify specific disk slices to mirror so you don't have to do the entire drive. It should take you less than five minutes to setup once you've read the docs. -Damian ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
