The best I can lay my hands on is the O'Reilly Unix Backup & Recovery by W. Curtis Preston. ISBN # 1-56592-642-0. Essentially, what I use is based on the syntax of: /sbin/xfsdump -f /dev/st0 -o -l 0 -F -L /mountpoint. In reverse, to restore I use /sbin/xfsrestore -if /dev/st0 /mountpoint. The interactive restore allows you to select or skip a dump, and when selecting, for example a restore of /usr, if you only want to restore /usr/local then select 2)Restore this dump, at which point you can do an "ls" to view the files in the dump, do an "add *" to select everything, or "add /local" for the /usr/local directory, or "add /usr/local/foo" for the individual file name. Each selection is indicated with an asterisk. When done selecting, simply do an "extract" and it's done. Remember that xfsdump backs up by the mountpoints, and uses the non-rewinding device. The script that I use, modified a tad for each individual machine is below. (Watch out for the linewrap)
Andrew, do you know of any good documentation on xfsdump? I've been unable to find much that sanely walks a person through using it for backup & recovery.

This is what I use for DAT & DLT tape drives, you must add "-q" to the XFSDUMP line for QIC or Travan drives.
