cdbkup did just exactly the same, but with GNU tar instead of dump/
restore. There are two helper programs - cdcat and cdsplit - allowed
to read/write backups from/to multiple CDs.

My (so not even started yet, in planning stage) effort was to create
modular cdbkup tool, i.e. it would be possible to use any real backup/
restore tools (named collectors) and pass the data through compressors,
encryptors (aka filters), then wrote it to any storage, using media
drivers. Please read details about cdbkup at:
