bedup ā€” program for deduplication program with additional knowledge of burp

Synopsis

bedup [options]

A file deduplication program with additional knowledge of burp storage directories. This program comes with the burp backup and restore package.

Options

-c path

Path to config file (default: /etc/burp/burp.conf).

-g <list of group names>

Only run on the directories of clients that are in one of the groups specified. The list is comma-separated. To put a client in a group, use the 'dedup_group' option in the client configuration file on the server.

-h|-?

Print help text and exit.

-d

Delete any duplicate files found. (non-burp mode only, use with caution!)

-l

Hard link any duplicate files found.

-m <number>

Maximum number of hard links to a single file. (non-burp mode only - in burp mode, use the max_hardlinks option in the configuration file) The default is 10000. On ext3, the maximum number of links possible is 32000, but space is needed for the normal operation of burp.

-n <list of directories>

Non-burp mode. Deduplicate any (set of) directories.

-v

Print duplicate paths. Useful if you want to double check the files that would be hard linked or deleted before running with one of those options turned on.

-V

Print version and exit.

By default, bedup will read /etc/burp/burp.conf and deduplicate client storage directories using special knowledge of the structure.

With '-n', this knowledge is turned off and you have to specify the directories to deduplicate on the command line. Running with '-n' is therefore dangerous if you are deduplicating burp storage directories.
