# bedup(8)

deduplication program with additional knowledge of burp

## NAME

bedup - 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.
