Description
|
|
~~~~~~~~~~~
|
|
|
|
Recreate the contents of existing archives.
|
|
|
|
Recreate is a potentially dangerous function and might lead to data loss
|
|
(if used wrongly). BE VERY CAREFUL!
|
|
|
|
Important: Repository disk space is **not** freed until you run ``borg compact``.
|
|
|
|
``--exclude``, ``--exclude-from``, ``--exclude-if-present``, ``--keep-exclude-tags``
|
|
and PATH have the exact same semantics as in "borg create", but they only check
|
|
files in the archives and not in the local filesystem. If paths are specified,
|
|
the resulting archives will contain only files from those paths.
|
|
|
|
Note that all paths in an archive are relative, therefore absolute patterns/paths
|
|
will *not* match (``--exclude``, ``--exclude-from``, PATHs).
|
|
|
|
``--chunker-params`` will re-chunk all files in the archive. This can be used to
|
|
switch existing archives to different chunker parameters (or a different chunker
|
|
algorithm), so they deduplicate with archives created using these parameters.
|
|
|
|
**USE WITH CAUTION.**
|
|
Depending on the paths and patterns given, recreate can be used to
|
|
delete files from archives permanently.
|
|
When in doubt, use ``--dry-run --verbose --list`` to see how patterns/paths are
|
|
interpreted. See :ref:`list_item_flags` in ``borg create`` for details.
|
|
|
|
The archive being recreated is only removed after the new archive has been saved
|
|
completely. The new archive is created under the same name as the original one, so
|
|
while the operation runs, both exist side by side; they are told apart by their
|
|
archive IDs, as the new archive gets a different archive ID.
|
|
|
|
With ``--target`` the original archive is not replaced, instead a new archive is created.
|
|
|
|
When rechunking, space usage can be substantial - expect
|
|
at least the entire deduplicated size of the archives using the previous
|
|
chunker params.
|
|
|
|
If your most recent borg check found missing chunks, please first run another
|
|
backup for the same data, before doing any rechunking. If you are lucky, that
|
|
will recreate the missing chunks. Optionally, do another borg check to see
|
|
if the chunks are still missing. |
