1. I don't think e-sata is a problem although I don't have that myself.
2. If you want to keep a particular backup for a long period just create another with no space management and it will stay until you manually delete it. One of the great features of Macrium is that you can create as many mackup sets as you want.
A further piece of advice if you don't mind. Make sure you create and test that the recovery disk can see your backup drive. I have found the WinPE disk to be the most reliable.
