I have used Quarterback, Amiback, Mr. Backup, and Diavolo 2000 and would submit that the I use Quarterback the most as it is VERY reliable and easy to use but I am transitioning to Diavolo due to it's modern implementation, advanced features and best hope for future support and improvement. Well that is my long winded 2 cents worth. My 4000T is down for now but hope to be back in the Amiga game soon. :-D Oh yeah, several legal giveaways of Quarterback Tools exist via Amiga Mags and legal demo versions.
