Nightly Backups

backup_nightly_programs.cfg defines a shell script to perform nightly backups of important data directories.  Note, by means of the per-system #if directives, how different things are backed up, and backed up to different places, on different backup servers.

On the piktmaster system, we would install the backup_nightly.sh script to the PIKT slave system ottawa, for example, with the command:

# piktc -iv +P backup_nightly.sh +H ottawa

For more examples, see Samples.
