Hi all,
I appreciate all the comments and thoughts, thank you.
I'm just going to sum up what happened even though its a bit of a mess.
Basically, the requirements that were given around privacy and for it being a non-physical approach evaporated. The recipient of the data eventually came back and said the network in that part of the world is incapable of receiving large files, so please mail physical. So thats whats going to be done, a crypted external hard-drive. I am grateful that this is the solution was deemed acceptable because in this particular case it seemed the best.
The approach that we were preparing to do was to crypt and chunk using 7-zip which looks like a great product for exactly this types of problem. We were then going to make it available via sftp to the recipient. The reason for setting it up that way was so the recipient could take advantage of the faster download speeds (as compared to upload).
Thanks again, Micah

If network transfer is an option, tools like rsync or Unison over SSH are your friend. +1 for physical media for bandwidth though.

Hah, a bit simpler than my way.
But do keep in mind scp won't resume and if the sender is on a 2Mb up MTS DSL connection or similar it could take a looooong time to upload and no guarantee either side's connection or computers wouldn't go wonky during that time.
I'm not sure I did the math right, but I calculate at 2Mb/s 400GB would take 18 *days*??!?
scp would be good if you chunked the pieces real small, but bad for a single 400GB file, unless both sides have a great, fast, reliable pipe.
You've been spoiled by fast pipes, Rob!!
P.S. Maybe sneakernet would be a better option if your pipe is small... Buy 4 128GB SD cards or 1 500GB SSD drive, use split and gpg -c to chunk and encrypt; throw in a Xpresspost or UPS Express envelope and ship 1-2 day for around $15-$30. Figure 1 day to write the data (especially on slow SD cards, SSD would be waaay faster), 1-2 days en route. All done in 3 days. But you'll spend ~$250 on the cards/ssd, but you can keep it for use another day. _______________________________________________ Roundtable mailing list Roundtable@muug.mb.ca http://www.muug.mb.ca/mailman/listinfo/roundtable
