Split your backup file before creating the iso. At the moment FreeBSD can't handle big files on isofs. If I remember correctly, big means 1 GB, but I'm not sure. You should still be able to extract the file with isoinfo from the cdrtools port. Once I've burned the DVD, how can I rejoin the files created using the -split-output option so that I can reload the database from the dump file? The man pages for mkisofs, isoinfo and split weren't very helpful in this regard. You misunderstood the -split-output option. It splits the image itself, so that it can be saved on file systems which have trouble with big files. I guess files splitted with split(1) can be rebuild with cat, haven't tried it though.

The man pages for mkisofs, isoinfo and split weren't very helpful in this regard. 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]
