I think there is no single way to attack this problem, and 10 different people will give you 10 different answers. I've been working with the tapeless P2 format for several years now (as well as XDCam and SxS) and here is the advice I would give based on my experiences.

Normally in the field I would do straight to 2 different hard drives (sometimes 3) using Shotput. It allows for immediate, separate backups and it's very fast. However, because you're going to be on the road for so long I probably would consider going the LTO route in addition.

I would make sure that I had enough hard drive space to create at least 3 copies at any given location. So for example, if the conference is 3 days in Thailand, then have enough HD space to make sure you can save it all to the hard drives, and have at least 2 copies of everything.

At the end of every day (if possible) I would take what had been shot and put it on 2 LTO tapes. On the last day of the conference in that location, I would send one set of LTO's back to my office and keep the other set with me for the duration of the trip.

Once I received word that the LTO tape had been received, I would erase the files from the HD's I was using and prepare them for the next location.

So at no one point do you have less then 2 copies, and you end up with two sets of LTO tapes, in different locations, that are rock solid backups. If one is lost, changes are both will not be.

The LTO part would have been difficult a few years ago, but using one of the new drives from Cache-A will make this a lot easier to do on the road. The unit is a self contained solution for exactly what you're talking about. You don't need any special software, just a network connection between your Mac and the unit. You can even plug hard drives directly into the unit and copy files that way as well.

There are too many details to get into here, but I did write a review of one of their units on my blog at SuiteTake.com. You can read details on that by going here...

If you need more help then this, I am often hired on jobs like this to be their on-site archive technician (AT) and have traveled as far as Beijing and Bangkok doing jobs just like this.

I hope that you find this information helpful. Sounds like you have a great gig ahead of you.
