Description
|
|
~~~~~~~~~~~
|
|
|
|
Upgrade an existing Borg repository.
|
|
|
|
Borg 1.x.y upgrades
|
|
-------------------
|
|
|
|
Use ``borg upgrade --tam REPO`` to require manifest authentication
|
|
introduced with Borg 1.0.9 to address security issues. This means
|
|
that modifying the repository after doing this with a version prior
|
|
to 1.0.9 will raise a validation error, so only perform this upgrade
|
|
after updating all clients using the repository to 1.0.9 or newer.
|
|
|
|
This upgrade should be done on each client for safety reasons.
|
|
|
|
If a repository is accidentally modified with a pre-1.0.9 client after
|
|
this upgrade, use ``borg upgrade --tam --force REPO`` to remedy it.
|
|
|
|
If you routinely do this you might not want to enable this upgrade
|
|
(which will leave you exposed to the security issue). You can
|
|
reverse the upgrade by issuing ``borg upgrade --disable-tam REPO``.
|
|

Attic and Borg 0.xx to Borg 1.x
|
|
-------------------------------
|
|
|
|
This currently supports converting an Attic repository to Borg and also
|
|
helps with converting Borg 0.xx to 1.0.
|
|
|
|
Currently, only LOCAL repositories can be upgraded (issue #465).
|
|
|
|
It will change the magic strings in the repository's segments
|
|
to match the new Borg magic strings. The keyfiles found in
|
|
$ATTIC_KEYS_DIR or ~/.attic/keys/ will also be converted and
|
|
copied to $BORG_KEYS_DIR or ~/.config/borg/keys.
|
|
|
|
The cache files are converted, from $ATTIC_CACHE_DIR or
|
|
~/.cache/attic to $BORG_CACHE_DIR or ~/.cache/borg, but the
|
|
cache layout between Borg and Attic changed, so it is possible
|
|
the first backup after the conversion takes longer than expected
|
|
due to the cache resync.
|
|
|
|
Upgrade should be able to resume if interrupted, although it
|
|
will still iterate over all segments. If you want to start
|
|
from scratch, use `borg delete` over the copied repository to
|
|
make sure the cache files are also removed:
|
|
|
|
borg delete borg
|
|
|
|
Unless ``--inplace`` is specified, the upgrade process first
|
|
creates a backup copy of the repository, in
|
|
REPOSITORY.upgrade-DATETIME, using hardlinks. This takes
|
|
longer than in place upgrades, but is much safer and gives
|
|
progress information (as opposed to ``cp -al``). Once you are
|
|
satisfied with the conversion, you can safely destroy the
|
|
backup copy.
|
|
|
|
WARNING: Running the upgrade in place will make the current
|
|
copy unusable with older version, with no way of going back
|
|
to previous versions. This can PERMANENTLY DAMAGE YOUR
|
|
REPOSITORY! Attic CAN NOT READ BORG REPOSITORIES, as the
|
|
magic strings have changed. You have been warned. |
