bedup - deduplication program with additional knowledge of burp
A file deduplication program with additional knowledge of burp protocol 1 storage directo‐
ries. This program comes with the burp backup and restore package.
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.
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 protocol 1 client storage
directories using special knowledge of the structure.
With '-n', this knowledge is turned off and you have to specify the directories to dedu‐
plicate on the command line. Running with '-n' is therefore dangerous if you are dedupli‐
cating burp storage directories.
If you find bugs, please report them to the email list. See the website
<http://burp.grke.net/> for details.
