Feature List

Summary: This is Not BackupBuddy works fine right now.
Not all intended features are enabled yet.

Uses rsyc's hard link option to provide incremental backups on spinning media. No special software should need to be installed on any recent *nix distro.
Notifies administrator by email when errors have been detected.
Fault tolerant - if it "goes offline" and backups aren't performed for a while, it should "start working" gracefully and automatically.
No special setup beyond defining a config file should be required to get a new account running.
Fault aware - if something goes wrong, it will alert an admin. (by email)
Good logging - a quick preview of the log file(s) should tell everything that's going on.
Easy to configure - Somebody new to its use should be able to set it up in < 10 minutes once deps are met.
Disk Space Handling: You can define a threshold of max image size space to keep free.
