uses unique unguessable prefixes for the backups
Why? If you're worried about someone overwriting old backups, don't: You can't overwrite or modify archives in tarsnap. Once created they can only be read (if you have the read keys) or deleted (if you have the delete keys).

Once created they can only be read (if you have the read keys) or deleted (if you have the delete keys). Nice. Some reason I thought a write key would be able to overwrite as well. If that's not possible then yes it's not necessary to have random prefixes. Fyi, most of my tarsnap usage is in "set it and forget" mode so been a while since I perused the docs. The random prefixes would apply if you're using something that doesn't provide overwrite protection like pushing blobs directly to S3.
