bedup - deduplication program with additional knowledge of burp


bedup [options] A file deduplication program with additional knowledge of burp protocol 1 storage directo‐ ries. This program comes with the burp backup and restore package.


-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 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.
