Quote: "On a daily basis I copy my project onto five flash drives, one SD card and one external hard disk (I remove two of the flash drives). Sometimes I make copies to two further flash drives which I carry on my person when I go out (I mean, is this a mental illness or what?). I also upload a zip file to the cloud every few days or so."
Well, since you asked, this sounds to be bordering on an obsessive compulsive disorder.
It really depends on wether or not you feel the need to do this and if you feel anxiety if you try to just stop doing it for a week or if you just keep a single drive with the backup. Its not necessarily something that should cause problems in your daily life but if you happen to be in therapy I would certainly bring this up in conversation.
Personally, I have external USB drives where I copy over my project files, photos and documents every couple months. As far as game dev is concerned, I now always have 2 copies of a map file in case one of the models happens to be corrupted in my latest save so I can roll back.
