My 2 years project disappeared in 1 minutes? Oh man

I've recovered my projects back now.

Unity 5.6.0b9

I tried to remove some folder on Project Explorer ( It's empty folder, Before it's audio folder like attack 01,
attack 02 sound effect ) then Unity freezing for a sec ( It's normal thing when delete Unity will freeze for a sec ) >
Then I go on website watching something for waiting Unity doing their process.

Now I've come back after a while It's still freezing >
Then I was going to Task manager > Saw Unity not responding.

And I was swap to Visual Studio pop-up show to reload > I reload all. ( It's normal thing )

I'm nervous now and going to Window Explorer > My Project > It's gone it's all gone!! **********

Why! Oh my god! What is going on?

I will system restore now oh my god oh my god.

 

I've recovered my projects back now.

This is on Recorvery programs. File has deleted. ....



Now I'm recovered all Orphaned folder on Recovery program and tried to make my projects to life.

T_T

 

Oh man! I knew I should've used version control. Oh man! nobody on forums has any sympathy.

Sounds brutal but yeah - people, please. Version control. Daily backups at minimum.

 

It's bad enough to have no backups at all after that long time... but not even doing one when using a beta version?

Download page and all sticky posts say "Remember to backup your project before running it in a Unity beta"

Just a reminder to anyone else reading this thread.

 

Roger that. I will backup more, I've learned my big mistake today. T_T

 

Hate it when people learn the hard way work lost is never a good thing.
