I'm a newbie. I have a VIP 612, and am upgrading to a VIP922, to get the built-in Sling. (Can't even do a Sling accessory with my current receiver.) To prepare for the receiver swap: I know that I will lose all my recorded programs. Will I also lose my Timers? Is it possible to back up the contents of the current receiver onto a hard drive, and then copy them back to the new receiver? If so, will it back up just the recorded shows, or also the Timers? Do I have to pay Dish the one-time fee to attach a hard drive, or is that only for "expanding" storage space, and not for backing up? If I attach a hard drive for purposes of backing up, will whatever's on it now be written over, or the drive reformatted, or can the material on the receiver just be added to what's already there, without disturbing the drive's present contents? Does it depend how the drive is currently formatted? (NTFS, FAT 32, etc.) Thanks!
