I noticed that the eXdupe compression/archiving/deduplication utility was recently mentioned in another post here. It boasts some interesting features, and I've been playing with it for the past day. It's basically a cross-platform, highly multithreaded archival tool.

I'm curious if anyone here uses it in production or has any tips on how to leverage the tool in their environment. I'm looking for suggestions.
