As I'm sure many people do, I run my backup to an external drive that is often not connected because I don't want it to wear out for no reason. Sometimes when I plug it in, Windows loads it under a different drive letter. When I tried to run a backup from a disk under a different letter, it obviously failed, but the most shocking thing is that when I changed the drive letter to the one that FBackup expects and started the backup again, FBackup deletes the entire backup and starts over from scratch without even asking me.

This behavior is absolutely insane for a program that should give people peace of mind about their data. There are also certain things that were only stored on my backup drive due to space constraints, so now I have to use expensive data recovery software to dig into deleted files and hopefully recover files that are no longer on the drives I backed up to. Was there some option or checkbox that I accidentally misconfigured to make FBackup behave in such a ridiculous way, or is the software actually designed to work that way because I'm just baffled that a backup program would behave that way under any circumstances?
