[NTLUG:Discuss] Dirvish -vs- Duplicity

[David Stanaway]

Duplicity has a pretty good mailing list.

When I was re-hosting my personal mail/web VPS I was looking in to using
it, but honestly haven't had the time to delve.

The data is encrypted, but I don't recall how its incremental backups
handled deletion/moves.
