Description

|
~~~~~~~~~~~
|
|
|
|
Free repository space by deleting unused chunks.
|
|
|
|
borg compact analyzes all existing archives to find out which repository
|
|
objects are actually used (referenced). It then deletes all unused objects
|
|
from the repository to free space.
|
|
|
|
Unused objects may result from:
|
|
|
|
- borg delete or prune usage
|
|
- interrupted backups (maybe retry the backup first before running compact)
|
|
- backup of source files that had an I/O error in the middle of their contents
|
|
and that were skipped due to this
|
|
- corruption of the repository (e.g. the archives directory having lost
|
|
entries, see notes below)
|
|
|
|
You usually don't want to run ``borg compact`` after every write operation, but
|
|
either regularly (e.g. once a month, possibly together with ``borg check``) or
|
|
when disk space needs to be freed.
|
|
|
|
**Important:**
|
|
|
|
After compacting it is no longer possible to use ``borg undelete`` to recover
|
|
previously soft-deleted archives.
|
|
|
|
``borg compact`` might also delete data from archives that were "lost" due to
|
|
archives directory corruption. Such archives could potentially be restored with
|
|
``borg check --find-lost-archives [--repair]``, which is slow. You therefore
|
|
might not want to do that unless there are signs of lost archives (e.g. when
|
|
seeing fatal errors when creating backups or when archives are missing in
|
|
``borg repo-list``). |
