Being still in the beta stage, Google chrome can not be fully trusted to save and be running with all the information. It can crash anytime and some of the history/profile information can be lost. So its better to backup all the profile information.

Now, to backup your Chrome profile, just click on the 1st option - “Backup Profile” and the profile will be backed up in a few seconds to a minute, depending on the number of bookmarks, saved passwords and cache. It will be saved to a folder inside your chrome folder.
