It’s happy to see that Google Chrome released 1.0 final this quick, and I believe that Google is going to bring more surprises to us about this product. Before that, let’s have a look how to backup, restore, add or delete Google Chrome Profiles with a useful freeware – Google Chrome Backup.
To backup default profile
Run the program, you will see only one profile named User Data in the Google Chrome Profiles window. To backup, just click Run Wizard! button to bring out the backup wizard dialog. Select the Backup radio button and click next, then select Backup default profile radio button and click next. Click Browse button to specify a location you want to put the backup file (with .gcb extension) and click Finish button. Wait until you see the message "Saved to …", you now have had the default Google Chrome profile saved successfully.
To backup user created profile
Still click the Run Wizard! button, but this time select "Select a profile to backup" when you are asked to choose which profile to save. I believe you know what to do next 
To add a new profile
In the program’s main window, click Profile button and choose New Profile, input a Profile Name you like, for example logger, then press OK button. Now you got a new Google Chrome profile in c:logger folder, and a shortcut to launch it in your desktop.
To remove a profile
Simply right click the profile name in the list, and select Delete. But by doing this, neither the profile folder nor the shortcut is actually deleted from your system. What the program did is removing the relevant entry in one of its own setting files – profiles.dat. However, you can delete the profile folder and shortcut manually if you want.
To restore a profile(or copy one profile’s setting to another)
Run the wizard, and select Restore, Browse to the .gcb file you backed up and click Next, choose which profile you want to restore and click Next, Restore.
Notes
When I click the Preferences of this program, it crashed. I tried several time, and got the same result, so I don’t know what settings it have.
You can manually create a shortcut with switch -user-data-dir="logger", this will create a folder logger in root dir of C drive if it does not exist.
Another useful switch is –incognito, which lets you start Google Chrome in private mode (incognito window).
We know that Firefox comes with a built-in Profile Manager to manage multi user profile, it’s good for Google Chrome to have this feature in the future release.
Different profiles can hold different bookmarks, cookies and other user data, so it’s good for people who need to separate working and life.
