I'd like to hear what internal mechanisms people are doing to backup
afs. It seems like everyone has their own special system to backup afs.
I'm curious about why that's so and why none of the major open source
backup software has support for afs.

When I looked at the ones available (both open source and closed) I was
woefully unimpressed. Many of them seemed fragile or problem-prone.

Specifically I'm interested in how many of them can do:
 - volumeset backups or backup by wildcarded volume/partion names
 - full volume restores
 - directory restores preserving acls
 - individual file restores
 - incremental backups
 - backups spanning tapes
 - 100+GB volume backups and restores
