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.

Which, come to think of it, looks close to the time you estimated. 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. Craig
