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).
|
|
|
|
``--recompress`` allows one to change the compression of existing data in archives.
|
|
Due to how Borg stores compressed size information this might display
|
|
incorrect information for archives that were not recreated at the same time.
|
|
There is no risk of data loss by this.
|
|
|
|
``--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 (or recompressing), space usage can be substantial - expect
|
|
at least the entire deduplicated size of the archives using the previous
|
|
chunker (or compression) 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). |
