Backup with online and offline storage

Getting Help

Hi, I’ve been using restic for a while and really like what it’s offering. I’m thinking about if I can use it in a new way:

Suppose I have a large repository that I store mainly on an external HDD drive. I want to put this HDD drive offsite, so I can only backup to this drive, say, once a year. In between the yearly main backup, I want to keep backing up daily to another online repository (e.g. B2), but only storing new data that’s not available in the main repository. In case I need to restore, I can get the HDD drive in the same location, merge the two repository and restore the files.

I think rustic has a concept for cold / hot repo, where the cold repo could the HDD drive. It almost fits my new use case, except that rustic requires that the cold repo is always available, where my external HDD drive won’t be plugged in.

Is this use case possible with restic or some other kind of backup tool?

Restic expects that all files in a repository are always accessible. There’s no support for partial repositories.

Got it, thank you for the reply.

I think I can make it work by maintaining the full repository locally. Once a year replicate the repository to the external HDD drive.
