[International / GSM] Nandroid files - getting them to my computer..

Still new to the rooting stuff but I had another quick question.

So I have root, have downloaded ROM manager and used it to back up my current ROM.

1) is this backup of my current ROM a full nandroid backup?
2) the files save to the sd card of my phone, but I would like to also copy them to my laptop to have - how would I go about doing this.
3) is there a better/more efficient way to make nandroid backups.

Thanks for all the help - this forum is a lifesaver!

You can move them from your phone to the CPU with a file explorer on the SD. You can also use something like wifi file explorer but I have had issues with larger files corrupting over it you could also dropbox the nandroid backups.
