Hi Graham,

Thanks for your reply. Sorry for not getting back to you sooner.

Yes, you are right, of course. I think I was just surprised that the dry
run took as long as it did, so that's where my mind was at when I was
thinking the connection wasn't the bottleneck. I was wrong.

Turned out the upload finished about 12-16 hours (if I remember
correctly) sooner than either of us calculated.

The cron job has been happily running all week, so things are good.
However, the script at https://www.tarsnap.com/tips.html#receive-mail
refers to an output file that isn't actually created, so should I be
specifying the output file name on the command line or somewhere else?
Doesn't seem like it's needed though, as cron sends along the output
anyway.
