Steam Games Backup (Steam cuts 50-100% of game data) (no appmanifest files!)

Steam recognizes and attempts to recover or use existing files, it ends up shoving the entire folder to a separate download folder and then starting from scratch to download the game again.

I backed up some game one day ago aprox due to PC problems, I return today to install them, for example, ArmA 3, both equals same size upon copying them over again, I press install, it does its thing and checks existing data, then it just throws away 50% of the game and tells me I have to download it again, is this really how it works or am I doing something wrong?

Help/Tips appreciated as my net is far from good, it's also limited.

EDIT: It turns out to be that I had deleted ALL of my appmanifest files that is bound to the downloaded games, and I don't know if I can restore theese manually or if I'm boned. I've already tried some but maybe I'm doing it wrong since it dosent wanna accept the game at all.

built-in backup backup 75-99% of game, other DL from steam cdn
if your backup used only 50% it mean new game updates, broken backup or incorrect backup
you can backup game folder + %gameID%.asf

Life crisis averted, it turned out to be a simple RAM error...
Not sure if broke or just shady. Anyways, I'm back! :D

=> data on hdd broken when you make backup

Hm... So I dropped the oar and I cannot reach it?

It sucks since ArmA 3 wanted me to DL above 20 GB of data and the full game basically sits in the backed up location.

Tested on one game, basically 99% of the game data was USELESS. And also, that RAM issue was nothing, I managed to back up all my data and i ensured multiple times it fitted the size of both sides.

I also did the manual way of copying steamapps and Steam.exe and then copying them back over, this did nada to help me get my games back.

Thanks for the answers, I'll just accept it being my fate and will delete this thread shortly.

I do not have Arma 3 but all my game perfectly archived and restored from the archive, the majority - without downloading any files from the Internet, in addition to security certificates and asf

I remember doing this priciple before, asoon as Steam booted up all games lit up in white, I dident even need to press install, it was all play instantly, but I still had to verify some games manually...

Apparently I couldent... But there's a button for it. >:c

I think I know now why my DL refuses to coop, it is because I were stupid enough to consider all the .acf files in the folder crap so I deleted them, I think that is my root cause for now, do you perhaps know any tips about this?

If all possible, I'd gladly restore them manually as it is my only choice.
