Rookie mistake!

Hi There.

I was wondering whether there's a simple way to restore my Centos OS? I was busy cleaning some files and wasn't paying attention to what I'm doing which ended up in my deleting allot of system files ... Lib64 and most likely a bunch of other. I've been able to restore the Lib64 folder and most libraries seems present but the system boots up to the point where I need to login but doesn't accepts my Username / password. There's also an error that flashes up which is most likely more missing files.

So my question is , instead of trying to figure out what files are still missing , isn't there perhaps an easier method to just re-install / restore the OS to scratch without loosing any data? I really want to try and avoid moving my data since it's a mailserver which I need to get back up ASAP so moving 400GB of space from and back is going to take to long.

Thanks in advance,

Unfortunately, not really. Best thing to do would be to boot from rescue media and back up all the data you need before you start to try to fix it. I suspect you're in for a reinstall but you could try checking the logs in /var/log for the errors that cause it to fail and fix those one by one.
