Reading the setup info it's BorgBackup 1.1.0b6 and the author confirm 
here:

https://news.ycombinator.com/item?id=14796936

Maybe borg improved from attic, but its not the point. Borg, attic, 
duplicacy based on deduplication using massive higher storage space in 
relation to duplicity (and rdiff-backup?). I dont' understand why 
file-based delta is more storage efficient then deduplication which can 
consolidate chunks from all files in the repo. I expect the opposite 
storage use ratio comparison.

Also anyone can comment borg CPU/RAM use in comparison to other?
