Add additional file to existing snapshot


I am doing a backup to my project. Each day a new snapshot is created.
However I have also a database dump that is on different VM that I like to include it in the daily snapshot.

Is it possible somehow to append additional file to the snapshot that is created ? I saw in the docs that it is possible to remove file from the snapshot but did not find how can I add file.

This is an open issue, see Merge multiple snapshots into one OR Append operation · Issue #3792 · restic/restic · GitHub.
Until this is solved, you can try out rustic which already implements a merge command.

Edit: Seems like there is also an experimental PR, see backup --files-from-verbatim allow merging snapshots by gmgigi96 · Pull Request #3405 · restic/restic · GitHub
