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
for files in the archives and not in the local file system. If PATHs are specified,
the resulting archives will only contain files from these 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 have upgraded Borg 0.xx archives deduplicate with Borg 1.x archives.
**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 operation completes. The
archive that is built during the operation exists at the same time at
"<ARCHIVE>.recreate". The new archive will have 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 you recently ran borg check --repair and it had to fix lost chunks with all-zero
replacement chunks, please first run another backup for the same data and re-run
borg check --repair afterwards to heal any archives that had lost chunks which are
still generated from the input data.
Important: running borg recreate to re-chunk will remove the chunks_healthy
metadata of all items with replacement chunks, so healing will not be possible
any more after re-chunking (it is also unlikely it would ever work: due to the
change of chunking parameters, the missing chunk likely will never be seen again
even if you still have the data that produced it).
