I'm also quite pleased with borg. I haven't had to do any full restores with it, but minor testing of restores and backing up has been a breeze. 

One aspect is that I'm using a different repository for each host, so my system files and other duplicated files are not deduplicated between the per-host backup repository, but with each incremental backup I do see quite good deduplication results. The deltas between runs (of the same host, of course) are usually quite small.
