Description
|
|
~~~~~~~~~~~
|
|
|
|
This command transfers archives from one repository to another repository.
|
|
Optionally, it can also upgrade the transferred data.
|
|
Optionally, it can also recompress the transferred data.
|
|
|
|
It is easiest (and fastest) to give ``--compression=COMPRESSION --recompress=never`` using
|
|
the same COMPRESSION mode as in the SRC_REPO - borg will use that COMPRESSION for metadata (in
|
|
any case) and keep data compressed "as is" (saves time as no data compression is needed).
|
|
|
|
If you want to globally change compression while transferring archives to the DST_REPO,
|
|
give ``--compress=WANTED_COMPRESSION --recompress=always``.
|
|
|
|
The default is to transfer all archives.
|
|
|
|
You could use the misc. archive filter options to limit which archives it will
|
|
transfer, e.g. using the ``-a`` option. This is recommended for big
|
|
repositories with multiple data sets to keep the runtime per invocation lower.
|
|
|
|
General purpose archive transfer
|
|
++++++++++++++++++++++++++++++++
|
|
|
|
Transfer borg2 archives into a related other borg2 repository::
|
|
|
|
# create a related DST_REPO (reusing key material from SRC_REPO), so that
|
|
# chunking and chunk id generation will work in the same way as before.
|
|
borg --repo=DST_REPO repo-create --encryption=DST_ENC --other-repo=SRC_REPO
|
|
|
|
# transfer archives from SRC_REPO to DST_REPO
|
|
borg --repo=DST_REPO transfer --other-repo=SRC_REPO --dry-run # check what it would do
|
|
borg --repo=DST_REPO transfer --other-repo=SRC_REPO # do it!
|
|
borg --repo=DST_REPO transfer --other-repo=SRC_REPO --dry-run # check! anything left?
|
|
|
|
|
|
Data migration / upgrade from borg 1.x
|
|
++++++++++++++++++++++++++++++++++++++
|
|
|
|
To migrate your borg 1.x archives into a related, new borg2 repository, usage is quite similar
|
|
to the above, but you need the ``--from-borg1`` option::
|
|
|
|
borg --repo=DST_REPO repocreate --encryption=DST_ENC --other-repo=SRC_REPO --from-borg1
|
|
|
|
# to continue using lz4 compression as you did in SRC_REPO:
|
|
borg --repo=DST_REPO transfer --other-repo=SRC_REPO --from-borg1 \
|
|
--compress=lz4 --recompress=never
|
|
|
|
# alternatively, to recompress everything to zstd,3:
|
|
borg --repo=DST_REPO transfer --other-repo=SRC_REPO --from-borg1 \
|
|
--compress=zstd,3 --recompress=always
|
