Description
|
|
~~~~~~~~~~~
|
|
|
|
Recreate the contents of existing archives.
|
|
|
|
This is an *experimental* feature. Do *not* use this on your only backup.
|
|
|
|
--exclude, --exclude-from and PATH have the exact same semantics
|
|
as in "borg create". If PATHs are specified the resulting archive
|
|
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, --compression-from, PATHs).
|
|
|
|
--compression: all chunks seen will be stored using the given method.
|
|
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 or Attic archives deduplicate with
|
|
Borg 1.x archives.
|
|
|
|
USE WITH CAUTION.
|
|
Depending on the PATHs and patterns given, recreate can be used to permanently
|
|
delete files from archives.
|
|
When in doubt, use "--dry-run --verbose --list" to see how patterns/PATHS are
|
|
interpreted.
|
|
|
|
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.
|
|
When recompressing expect approx. (throughput / checkpoint-interval) in space usage,
|
|
assuming all chunks are recompressed.
