Big initial upload

[Gregory Orange <gregory.orange@calorieking.com>]

Hi tarsnap folks,

I'm considering tarsnap for our backups. I am mildly concerned about our 
Internet uplink speed to get the data to tarsnap on a nightly basis, but 
I am much more concerned about that same uplink for initially getting 
all of the data uploaded. I've trawled through the mailing list archives 
a bit (is there a way to search them?) and looked at FAQs etc but I'm 
not sure exactly how I would handle it.

The numbers are in the order of 1TB of data over Australian ADSL at a 
maximum of 1 megabit per second uplink. By my reckoning, that might 
finish in 36 hours, but is more likely to be double that.

Is there a supported way to seed our backups with say an encoded file or 
files on a USB drive? If not, is it being considered for the future?

Greg.
