Multi-Disk CD Backup Solutions for Linux?

waldowaldo asks: "I have looked high and low for a good way to back up a server hard drive to CDs, but cannot find anything. There are good programs for collecting files and writing them to a single disk (such as cdrecord), but nothing for multiple CDs (that I can find). Anyone seen anything that'll do this?"

  1. CD-RAID0 by technos · · Score: 4

    I had occasion to need a transport medium for several large video files approaching 1.8G in size each. While I could have always mailed a tape, I decided to do something more novel. CDROM-RAID0

    I created three 620M files (dd if=/dev/zero blah..), hooked them to loopback devices, mdadd'ed and mdran them, then slapped a ext2 fs across them. After writing the video to the RAID volume (Don't forget to sync!) I burned each file to a CD-RW, and included a short mount/losetup/mdrun/etc script on the first CD.

    The best part about the arrangement was that you could play the high-bandwidth video directly from the associated CD's, with no intermediary layer or jacking the buffer up.. (The 'seek' lag was roughly double normal, but I could pull a true 40X off of the three 16X(max) CDROM drives.)

    If you want more implementation detail, just ask!
