How are you going to back up once you do get it over there?

Besides what the others have mentioned about compressing the file (I've seen around 10 to 1, commonly, but of course you need to consider compression/decompression time if you have a small window), have you checked to be sure the file system and network processes are not going bonkers?

There are also compress-on-the-fly options, where you pipe the output of exp into compress, and thence to a file, or even to uncompress/imp if you have proper mounting options.
