borg-rcompress - Repository (re-)compression
borg [common options] rcompress [options]
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.
See
borg-common(1) for common options of Borg commands.
