borg [common options] recreate [options] [PATH...]
positional arguments |
||
|
paths to recreate; patterns are supported |
|
options |
||
|
output verbose list of items (files, dirs, …) |
|
|
only display items with the given status characters (listed in borg create --help) |
|
|
do not change anything |
|
|
print statistics at end |
|
Include/Exclude options |
||
|
exclude paths matching PATTERN |
|
|
read exclude patterns from EXCLUDEFILE, one per line |
|
|
include/exclude paths matching PATTERN |
|
|
read include/exclude patterns from PATTERNFILE, one per line |
|
|
exclude directories that contain a CACHEDIR.TAG file (http://www.bford.info/cachedir/spec.html) |
|
|
exclude directories that are tagged by containing a filesystem object with the given NAME |
|
|
if tag objects are specified with |
|
Archive filters — Archive filters can be applied to repository targets. |
||
|
only consider archives matching all patterns. see “borg help match-archives”. |
|
|
Comma-separated list of sorting keys; valid keys are: timestamp, archive, name, id, tags, host, user; default is: timestamp |
|
|
consider first N archives after other filters were applied |
|
|
consider last N archives after other filters were applied |
|
|
consider archives between the oldest archive’s timestamp and (oldest + TIMESPAN), e.g. 7d or 12m. |
|
|
consider archives between the newest archive’s timestamp and (newest - TIMESPAN), e.g. 7d or 12m. |
|
|
consider archives older than (now - TIMESPAN), e.g. 7d or 12m. |
|
|
consider archives newer than (now - TIMESPAN), e.g. 7d or 12m. |
|
|
create a new archive with the name ARCHIVE, do not replace existing archive |
|
|
add a comment text to the archive |
|
|
manually specify the archive creation date/time (yyyy-mm-ddThh:mm:ss[(+|-)HH:MM] format, (+|-)HH:MM is the UTC offset, default: local time zone). Alternatively, give a reference file/directory. |
|
|
select compression algorithm, see the output of the “borg help compression” command for details. |
|
|
rechunk using given chunker parameters (ALGO, CHUNK_MIN_EXP, CHUNK_MAX_EXP, HASH_MASK_BITS, HASH_WINDOW_SIZE) or default to use the chunker defaults. default: do not rechunk |
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 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 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 re-create the missing chunks. Optionally, do another borg check, to see if the chunks are still missing).
# Create a backup with little but fast compression
$ borg create archive /some/files --compression lz4
# Then compress it - this might take longer, but the backup has already completed,
# so no inconsistencies from a long-running backup job.
$ borg recreate -a archive --recompress --compression zlib,9
# Remove unwanted files from all archives in a repository.
# Note the relative path for the --exclude option - archives only contain relative paths.
$ borg recreate --exclude home/icke/Pictures/drunk_photos
