[MacTUG] AFP548 - Faking Filesystem Snapshots on Mac OS X Server

[Marlon A. Griffith]

Most other operating systems on the market allow you to make a 
"snapshot" of a filesystem. Using these snapshots you can provide 
easy access, and in many cases self-service access, to instant 
backups of the files and folders. This functionality is usually part 
of the filesystem and one that HFS, in its now numerous forms, does 
not support. We can however fake it, and provide easy, self-servicing 
access backups to our users on some shares, in some cases. We call it 
the GhettoSnap.
