Here is a simple way to backup the preference and settings of Google chrome browser.This is a manual way in which you don’t need to download any freeware software.
This will let you backup the whole Google chrome web browser settings which means you cannot backup the passwords,cache,saved option or bookmarks.
Just go to run (windows+r) and type the following
C:Documents and Settings<user account>Local SettingsApplication DataGoogleChromeUser DataDefault
Make sure you change the <user account> to your system account name and change the drive depending on the OS installed.Now a window pops out showing cache,plugins,web history and many more files.Copy the file named Preference and save it anywhere in your hard disk.Next time when your chrome crashes then download and re install Google chrome and paste the “Preference” file back to the same folder to retrieve the preference and settings!
This is another way to do a full backup of Chrome browser by downloading a freeware software.
Download a free software called “Google chrome backup” which will not only backup Google chrome data but also restore it easily! Chrome data includes all settings/preference including password backup,bookmark backup,cache and also other saved option which are both backed up and restored (whole profile) using Google chrome backup freeware.
