Description
|
|
~~~~~~~~~~~
|
|
|
|
Repository (re-)compression (and/or re-obfuscation).
|
|
|
|
Reads all chunks in the repository (in on-disk order, this is important for
|
|
compaction) 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.
|
|
|
|
Every ``--checkpoint-interval``, progress is committed to the repository and
|
|
the repository is compacted (this is to keep temporary repo space usage in bounds).
|
|
A lower checkpoint interval means lower temporary repo space usage, but also
|
|
slower progress due to higher overhead (and vice versa).
|
|
|
|
Please note that this command can not work in low (or zero) free disk space
|
|
conditions.
|
|
|
|
If the ``borg rcompress`` 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 ``borg rcompress``
|
|
is used interactively.
|
|
|
|
You do **not** need to run ``borg compact`` after ``borg rcompress``. |
