If someone is accidentally pouring diesel in their gasoline engine car do you tell them to stop or do you tell them what the price of diesel is?

Haha! And if you bothered to read instead of judge, you would see i mention compressing already encoded/compressed files offer no benifit. Try reading before jumping to conclusions next time.

ClickClick wrote:3) Something truly random here, the cache folder for Google Chrome. For the test, there were 2,988 files and they totaled to 362MB
ClickClick wrote:4) Before modern fast internet, when downloading in Steam, I would keep a backup of my games in compressed form on a disc in case I had to reinstall or my HDD died, so found my old Half-Life backup folder. This folder contained 4,510 files and totaled to 409MB for me.

6+ GB SQL database. With 7zip as the compressor.
Going to ZIP gets it down to around 600+ MB. Takes quite some time.
Going to 7z gets it down to around 200 MB. Much faster.
With 7z it is able to use all 8 threads on the CPUs whereas with the ZIP it only uses 2. I thought that only mattered if there were multiple files being included rather that just one big .BAK file, but I guess not. I don't believe the compression is enabled on the database so it's ripe fer compressin'.
With this in mind, I'm going to redo all our schedule task compress and backup scripts to use 7z instead of ZIP. I had done ZIP in the past because it could be opened natively in Windows but hell, 7zip is easy enough to get if need be for recovery purposes.

Whether or not this will be compressible probably depends on the game(but I'd assume most have a compressed package format), but it's still misplaced. For one thing, Steam already has a built-in backup system you can use. For another, who really bothers these days (as you even say)? "Modern fast internet" makes it somewhat silly for most users.

But with them keeping track of all the games you own and you can download them to pretty much any machine you get or use I do not think it is a huge priority to them. I just with the Steam would store your game's progress and achievements for each and every game. So when you install a game on your rig it remembers your place and level in the game.
At least for games that do not do this automatically already.

Can I make a few suggestions?
Glorious wrote:Again, this might seem overly critical, but if you want people to appreciate the work you've obviously done, they are all things you ought to pay some attention to.
The Egg wrote:It's not misplaced at all. The Steam Backup feature is a buggy piece of garbage that is incredibly sloooooow when it does work (rarely), and crashes nearly 100% of time once your game library surpasses a certain threshold. I have repeatedly done everything I can to get it to work, trying about once every 6 months for a period of several years, and on several different machines. I don't think Valve has updated this utility once in Steam's 10 year lifespan.
The Egg wrote:As far as compressibility of the games, my most recent 7-zip archive of the Steamapps folder took a 358GB library down to just under 244GB, using fairly conservative settings.
The Egg wrote:True, but some people have data caps to deal with, and a large Steam library like mine can be a problem. Others might not have blazing fast internet connections. 358GB at a modest 6mbit connection would be over 129 hours.
