Splitpipe is a program that allows the output of a program to span multiple volumes. Volumes might be DVD's, CD's, files, entire hard disks or floppies.

A command line says more than a thousand words:

# tar cz /home | splitpipe -s dvd -o 'growisofs -Z /dev/dvd=/dev/stdin'
To restore:
# joinpipe /dev/dvd | tar xz

The two lines above backup /home to one, or more DVDs, prompting the operator to change media once a volume is full. For more, see Examples, or a screenshot.

Features

Running MD5 checksum
Detects truncated volumes
Impervious to trailing garbage (which you get when piping raw data to cdrecord or growisofs)
Detects improper order of volumes on restore
- Allows user to insert proper volume when this happens
Each session has a UUID, so volumes from other backups are rejected
