How to extract a backup

Extract

When the worst happens—or you want to test your backups—the first step is to figure out which archive to extract. A good way to do that is to use the list action:

borgmatic list

(No borgmatic list action? Try the old-style --list, or upgrade borgmatic!)

That should yield output looking something like:

host-2019-01-01T04:05:06.070809      Tue, 2019-01-01 04:05:06 [...]
host-2019-01-02T04:06:07.080910 Wed, 2019-01-02 04:06:07 [...]

Assuming that you want to extract the archive with the most up-to-date files and therefore the latest timestamp, run a command like:

borgmatic extract --archive host-2019-01-02T04:06:07.080910

(No borgmatic extract action? Try the old-style --extract, or upgrade borgmatic!)

The --archive value is the name of the archive to extract. This extracts the entire contents of the archive to the current directory, so make sure you're in the right place before running the command.

Repository selection

If you have a single repository in your borgmatic configuration file(s), no problem: the extract action figures out which repository to use.

But if you have multiple repositories configured, then you'll need to specify the repository path containing the archive to extract. Here's an example:

borgmatic extract --repository repo.borg --archive host-2019-...

Extract particular files

Sometimes, you want to extract a single deleted file, rather than extracting everything from an archive. To do that, tack on one or more --path values. For instance:

borgmatic extract --archive host-2019-... --path path/1 path/2

Note that the specified restore paths should not have a leading slash. Like a whole-archive extract, this also extracts into the current directory. So for example, if you happen to be in the directory /var and you run the extract command above, borgmatic will extract /var/path/1 and /var/path/2.

Extract to a particular destination

By default, borgmatic extracts files into the current directory. To instead extract files to a particular destination directory, use the --destination flag:

borgmatic extract --archive host-2019-... --destination /tmp

When using the --destination flag, be careful not to overwrite your system's files with extracted files unless that is your intent.

Database restoration

The borgmatic extract command only extracts files. To restore a database, please see the documentation on database backups and restores. borgmatic does not perform database restoration as part of borgmatic extract so that you can extract files from your archive without impacting your live databases.
