Answer #1
in short : the one last backup before the site got hacked … that way u will have the least data loss…
Answer #2
What you need to do, is take a backup of what you currently have, then restore the most recent one, and see if it is good. If not, restore the one before that, etc.
Answer #3
Let me see if got this right, So your site was hacked and all you care about is restoring it to it’s previous state?
Don’t get me wrong, I’m not saying that’s not important, But you are clearly missing the bigger picture here!
You have to figure out how this happened if you don’t want it to happen again!
There are multiple possibilities, Such as:
1. Your PC was hacked/keylogged and your login credentials were stolen.
2. Someone gained access to your email account (Either by guessing the password or hacking your PC) and restored the password to it.
3. It could be an SQL Injection/RFI vulnerability in WordPress (Or one of the plugins you use)
You could just have a look at the logs in order to figure it out (If you know what to look for). You could also check if there
are any known vulnerabilities in the wordpress/plugins versions you use by looking em on these sites:

4. It could be improper permissions on key configuration files.
5. It could be a server level hack (But this will be difficult to look into unless you’re on a VPS/Dedi)
Better figure it out (Unless you want a repeat!)

Sigh. That is a full cPanel backup, you need to restore it in cPanel (or possibly WHM). Open a ticket with your host if you cant do this on your own, you will need to provide the backup or the location of the backup on the server.
You are welcome to restore it manually, but this would be way to complicated for you.

OK,what to do with this
Now when i make restore for my backup the mysite run fine ((every thing is there)), but i can’t log-in to the Dashboard, it tell me to install wordpress ?

If i install the wordpress mysite will change to new site ((my site but without any topic)) so what to do to log-in to my dashboard of my site without install new wordpress ?
