I’m considering Restic and Backblaze B2 as my backup solution. I’m a little worried having read about the potential for unexpected restore costs. For example, I’ve read restoring lots of little files adds to the cost (reference). What are the things to look out for when backing up and restoring that can add to the cost? Are there any best practices to keep costs down?
I’d suspect a zip could be problematic for incremental backups. Though that’s not a bad idea for files that won’t be changing regularly (photos, archives).
