Having the entire backup as a single file is interesting, but does it matter?
Restic has a similar featureset (deduplicated encrypted backups), but almost certainly has better incremental performance for complex use cases like storing X daily backups, Y weekly backups, etc. At the same time, it struggles with RAM usage when handling even 1TB of data, and presumably ptar has better scaling at that size.
