Hi Chris, The idea is sane to start with, however i fail to see the point in using the loopback part. you can use mkisofs not only to create empty filesystems, but also to fill them up with all the files/folders in a (pre-build) tree. (saves you some trouble, suggest 'man mkisofs')
As a second point, if all fits on one cdr the only purpose of doing tar+gzip is to make several backups on once cdr. (perhaps this part can also be skipped). Last point: lifetime of cd-rw's IS MOST DEFINITLY NOT ENDLESS. i suggest you solve this in your backup plan, by using multiple cd-rw's and backuping every day, adding one new cd-rw every week and archiving the oldest cd-rw at the same time. Hope this helps, Nico ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <debian-user@lists.debian.org> Sent: Tuesday, June 19, 2001 2:26 PM Subject: opinions please: auto-backup to CDRW > Hi, > > I've been thinking about something over the last few > days and was wondering if it classifies as "sane" - > opinions please! > > I have about 500Mb of variable data (theres only 4 > console only users and we arent mp3 freaks!) and a > CDRW.
