I have gone down this path too. I really don't like it because it
is, as you say, a safety net and I don't want to loosen it.

I don't quite understand your first comment though. The docs say
this for ClientTimeout:

      Timeout in seconds when listening for the transport program's
      (smbclient, tar etc) stdout. If no output is received during
      this time, then it is assumed that something has wedged during
      a backup, and the backup is terminated.

      Note that stdout buffering combined with huge files being
      backed up could cause longish delays in the output from
      smbclient that BackupPC_dump sees, so in rare cases you might
      want to increase this value.

      Despite the name, this parameter sets the timeout for all
      transport methods (tar, smb etc).

Especially the last sentence suggests that this also applies to
rsync and so I do not understand why an rsync backup would time out,
unless there was no more data for almost a day (72.000 seconds).
