You have obnam: `Really slow for large backups (from a benchmark between obnam and attic)` , but then, no section for attic itself. It's probably also wise to roughly group the backup systems by algorithm-class (e.g. separate rsnapshot from rdiff-backup from duplicity from attic/obnam/zbackup) since they result in different bandwidth and storage properties. Duplicity will need a full re-upload to avoid unbounded growth of both storage and restore-time, but such a re-upload is prohibitive for DSL users.
