Shell script attached. Basically it matches the files in: $BACKUP_DIR/$DATESTRING*.tar.gz It then creates and ISO file and burns to a CD, and fires off an email if=20 the backup fails. It also incrementally adds stuff to a CD, so you can=20 put in a blank CD and it'll keep adding stuff everytime the script is run=20 until the space fills up, and then you'll get an email. =2D-=20 Anish Mistry --nextPart1693951.au5ZfYkCLr Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (FreeBSD) iD8DBQBBkV+CxqA5ziudZT0RAgZKAKCYHAI89iGqudBvYFQfobWIVgF8SwCgreQI J0W+DScLEg2VfdKb0JP0eZ0= =FP4q -----END PGP SIGNATURE----- --nextPart1693951.au5ZfYkCLr-- --Boundary-00=_C+VkBl7gGMYK+xC--
