I've had good experiences with dirvish - backing up both locally and
from remote machines.
around 12TB of data synced/online backed up from one master to two
offsite copies, but thats a differnt use case :-p
Never heard of dirvish. Is it still maintained? It's written if Perl and depends on several modules, so it might not work forever...
rdiff-backup had a similiar problem (it was stuck on Python 2), but it has been put back to life recently, so I would give that a try.
