borg-repo-compress - Repository (re-)compression

                                                   2025-01-03                              BORG-REPO-COMPRESS(1)

       Repository (re-)compression (and/or re-obfuscation).

       Reads  all  chunks  in the repository and recompresses them if they are not already using the compression
       type/level and obfuscation level given via --compression.

       If the outcome of the chunk processing indicates a change in compression type/level or obfuscation level,
       the processed chunk is written to the repository.  Please note that the outcome might not always  be  the
       desired compression type/level - if no compression gives a shorter output, that might be chosen.

       Please note that this command can not work in low (or zero) free disk space conditions.

       If  the  borgrepo-compress  process  receives  a SIGINT signal (Ctrl-C), the repo will be committed and
       compacted and borg will terminate cleanly afterwards.

       Both --progress and --stats are recommended when borgrepo-compress is used interactively.

       You do not need to run borgcompact after borgrepo-compress.

          # recompress repo contents
          $ borg repo-compress --progress --compression=zstd,3

          # recompress and obfuscate repo contents
          $ borg repo-compress --progress --compression=obfuscate,1,zstd,3
