On the subject of DVD backups, I have found them to be somewhat lossy over time. For my large database backups, I use rar out of the ports and add recovery records in the archive (-rr) and and split them using its volume feature. I also use par2 to further add redundancy and it has saved my ass a couple of times when I went to get a backup from the year before. from a script I use /usr/local/bin/rar a -r -v45M -rr -p$PASS /backup/root/iso/acctDB.rar /sql-mnt/ /usr/local/bin/par2create -r20 /backup/root/iso/parfiles.par2 /backup/root/iso/*.rar The databases compress down to about 3G on the DVDs across 45MB files. par2 then creates recovery files that allow for upto 20% damage to the DVD. To restore the files, rar x acctDB.rar ---Mike -------------------------------------------------------- Mike Tancsa, Sentex communications http://www.sentex.net Providing Internet Access since 1994 [EMAIL PROTECTED], (http://www.tancsa.com) _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
