I didn't know that my google account wasn't in sync with my chrome for the last couple of months and now that I have link again, the restored record is several months old.

Now, that I've lost all my recent bookmarks and all other stuff...is there anything or anyway so I could revert the Google sync so I can get my bookmarks back?

Update 1

I have found that under C:\Users\Profile_Name\AppData\Local\Google\Chrome\User Data\Default there is a file named Bookmarks.bak that holds the old state of my bookmarks before the sync.

Update 2

Bookmarks is the file that holds the current(after sync) bookmark list. I replaced Bookmarks with Bookmarks.bak and restarted chrome, but still chrome isn't fetching information from the updated file.

So, I have my old bookmark information, but how to restore it in chrome.

Update 3 : solved

I still couldn't figure out why replacing the bookmarks file didn't work and aparently that's the only solution available on web.

I reinstalled everything and then copied the old bookmarks file. Then I got my bookmarks back again.
