To use dedup you have to first initialize the repository.

This will create .{snapshots,store} files in the repo directory. The
store file contains all the unique blocks. The snapshots file
contains all the revisions of files that have been deduplicated.
dedup only handles a single file at a time, so using tar is advised.

+For example, to dedup a directory tree you can invoke dup-pack(1) as
follows:
- tar -c ~/dir | dpack -m "$(date)" repo
+ tar -c ~/dir | dup-pack -m "$(date)" repo
The -m flag is used to attach an arbitrary message to the snapshot.
To list all known revisions run:
- dlist repo
+ dup-list repo
You will get a list of hashes. Each hash corresponds to a single file
(in this case, a tar archive).
To extract a file from the deduplicated store run:
- dunpack <hash> repo > snapshot.tar
+ dup-unpack <hash> repo > snapshot.tar
