I am a little short on storage space right now. So, I would like to take a ~50GB disk image from one computer and transfer it to another computer. Note that I am not using the disk image to create an operating system install, I am just transferring this data so that I have a backup. The computer that I am transferring to has extra space. Both computers have NTFS hard drives. 1) what method should I use to do the transfer? It seems as though ethernet is the best (the computer receiving the transfer has 10/100 ethernet). Also, I guess I should have both of the computers connected to my router, and not go through an additional switch? 2) should I check the file at each end? I am not too familiar with checksum but is that something that I should read up on?
