Michael, Thanks for the feedback.
On (1) I pushed a change <https://github.com/backuppc/backuppc/commit/69e44286c8ff66eff0e7e1ef8ed052945b0018a8> so that the Xfer timeout is started after backup expiry, duplication and refcounting. On (2), perhaps it should ignore a partial or active backup (which will have the most recent timestamp), and report just the most recent incr or full (ie, completed) backup? I pasted a diff that should do the trick if you want to try it out (warning - untested). On (3), I pushed a change <https://github.com/backuppc/backuppc/commit/19365d23cd4523874e2335db23eb7a89fa91253d> so that the status reporting is more accurate.
