In general, all you should need to do to upgrade borgmatic is run the following:
sudo pip3 install --user --upgrade borgmatic
See below about special cases with old versions of borgmatic. Additionally, if
you installed borgmatic without using
pip3 install --user,
then your upgrade process may be different.
Upgrading your configuration
The borgmatic configuration file format is almost always backwards-compatible from release to release without any changes, but you may still want to update your configuration file when you upgrade to take advantage of new configuration options. This is completely optional. If you prefer, you can add new configuration options manually.
If you do want to upgrade your configuration file to include new options, use
generate-borgmatic-config script with its optional
--source flag that
takes the path to your original configuration file. If provided with this
generate-borgmatic-config merges your original configuration into the
generated configuration file, so you get all the newest options and comments.
Here's an example:
generate-borgmatic-config --source config.yaml --destination config-new.yaml
New options start as commented out, so you can edit the file and decide whether you want to use each one.
There are a few caveats to this process. First, when generating the new
generate-borgmatic-config replaces any comments you've
written in your original configuration file with the newest generated
comments. Second, the script adds back any options you had originally deleted,
although it does so with the options commented out. And finally, any YAML
includes you've used in the source configuration get flattened out into a
single generated file.
As a safety measure,
generate-borgmatic-config refuses to modify
configuration files in-place. So it's up to you to review the generated file
and, if desired, replace your original configuration file with it.
Upgrading from borgmatic 1.0.x
borgmatic changed its configuration file format in version 1.1.0 from INI-style to YAML. This better supports validation, and has a more natural way to express lists of values. To upgrade your existing configuration, first upgrade to the new version of borgmatic.
As of version 1.1.0, borgmatic no longer supports Python 2. If you were already running borgmatic with Python 3, then you can upgrade borgmatic in-place:
sudo pip3 install --user --upgrade borgmatic
But if you were running borgmatic with Python 2, uninstall and reinstall instead:
sudo pip uninstall borgmatic sudo pip3 install --user borgmatic
The pip binary names for different versions of Python can differ, so the above commands may need some tweaking to work on your machine.
Once borgmatic is upgraded, run:
That will generate a new YAML configuration file at /etc/borgmatic/config.yaml (by default) using the values from both your existing configuration and excludes files. The new version of borgmatic will consume the YAML configuration file instead of the old one.
Upgrading from atticmatic
You can ignore this section if you're not an atticmatic user (the former name of borgmatic).
borgmatic only supports Borg now and no longer supports Attic. So if you're an Attic user, consider switching to Borg. See the Borg upgrade command for more information. Then, follow the instructions above about setting up your borgmatic configuration files.
If you were already using Borg with atticmatic, then you can upgrade from atticmatic to borgmatic by running the following commands:
sudo pip3 uninstall atticmatic sudo pip3 install --user borgmatic
That's it! borgmatic will continue using your /etc/borgmatic configuration files.
To upgrade to a new version of Borg, you can generally install a new version the same way you installed the previous version, paying attention to any instructions included with each Borg release changelog linked from the releases page. Some more major Borg releases require additional steps that borgmatic can help with.
Borg 1.2 to 2.0
New in borgmatic version 1.7.0 Upgrading Borg from 1.2 to 2.0 requires manually upgrading your existing Borg 1 repositories before use with Borg or borgmatic. Here's how you can accomplish that.
Start by upgrading borgmatic as described above to at least version 1.7.0 and Borg to 2.0. Then, rename your repository in borgmatic's configuration file to a new repository path. The repository upgrade process does not occur in-place; you'll create a new repository with a copy of your old repository's data.
Let's say your original borgmatic repository configuration file looks something like this:
location: repositories: - path: original.borg
Prior to version 1.7.10 Omit
path: portion of the
Change it to a new (not yet created) repository path:
location: repositories: - path: upgraded.borg
Then, run the
rcreate action (formerly
init) to create that new Borg 2
borgmatic rcreate --verbosity 1 --encryption repokey-blake2-aes-ocb \ --source-repository original.borg --repository upgraded.borg
This creates an empty repository and doesn't actually transfer any data yet.
--source-repository flag is necessary to reuse key material from your
Borg 1 repository so that the subsequent data transfer can work.
--encryption value above selects the same chunk ID algorithm (
commonly used in Borg 1, thereby making deduplication work across transferred
archives and new archives.
If you get an error about "You must keep the same ID hash" from Borg, that
means the encryption value you specified doesn't correspond to your source
repository's chunk ID algorithm. In that case, try not using
borgmatic rcreate --verbosity 1 --encryption repokey-aes-ocb \ --source-repository original.borg --repository upgraded.borg
Read about Borg encryption modes for more details.
To transfer data from your original Borg 1 repository to your newly created Borg 2 repository:
borgmatic transfer --verbosity 1 --upgrader From12To20 --source-repository \ original.borg --repository upgraded.borg --dry-run borgmatic transfer --verbosity 1 --upgrader From12To20 --source-repository \ original.borg --repository upgraded.borg borgmatic transfer --verbosity 1 --upgrader From12To20 --source-repository \ original.borg --repository upgraded.borg --dry-run
The first command with
--dry-run tells you what Borg is going to do during
the transfer, the second command actually performs the transfer/upgrade (this
might take a while), and the final command with
--dry-run again provides
confirmation of success—or tells you if something hasn't been transferred yet.
Note that by omitting the
--upgrader flag, you can also do archive transfers
between related Borg 2 repositories without upgrading, even down to individual
archives. For more on that functionality, see the Borg transfer
That's it! Now you can use your new Borg 2 repository as normal with borgmatic. If you've got multiple repositories, repeat the above process for each.
