AOL. It may also be worth it to not build an archive (with whatever method) and then propagate it through the cycle, but to make one archive to be stored on-site, and create an extra one to be stored off-site, best at another time and/or interval. I have several customers where a nightly backup goes off-site and another one is done around noon to be stored on-site. Off-site backups are tar.bz2 (for space reasons), on-site plain dump. If one method fails there´s always the other one. cheers, &rw -- -- Prof: So the American government went to IBM to come up with -- a data encryption standard and they came up with ... -- Student: EBCDIC! ----
