Upgrade an existing, local Borg repository.
|
|
|
|
When you do not need borg upgrade
|
|
+++++++++++++++++++++++++++++++++
|
|
|
|
Not every change requires that you run ``borg upgrade``.
|
|
|
|
You do **not** need to run it when:
|
|
|
|
- moving your repository to a different place
|
|
- upgrading to another point release (like 1.0.x to 1.0.y),
|
|
except when noted otherwise in the changelog
|
|
- upgrading from 1.0.x to 1.1.x,
|
|
except when noted otherwise in the changelog
|
|
|
|
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``.
|
|
|
|
See
|
|
https://borgbackup.readthedocs.io/en/stable/changes.html#pre-1-0-9-manifest-spoofing-vulnerability
|
|
for details.
|
|
|
|
Borg 0.xx to Borg 1.x
|
|
+++++++++++++++++++++
|
|
|
|
This currently supports converting Borg 0.xx to 1.0.
|
|
|
|
Currently, only LOCAL repositories can be upgraded (issue #465).
|
|
|
|
Please note that ``borg create`` (since 1.0.0) uses bigger chunks by
|
|
default than old borg did, so the new chunks won't deduplicate
|
|
with the old chunks in the upgraded repository.
|
|
See ``--chunker-params`` option of ``borg create`` and ``borg recreate``. |
