I have used this in the past to backup email accounts of resigned employees so we continue to stay well within the maximum number of active accounts for our free Google Apps. It generally works fine and it allows you to restore the emails to a different account name. (I sometimes temporarily restore an account to search for old emails). It seems to have some issues with restoring accounts with a lot of large emails (large or multiple attachments) especially those that have reached the 15GB quota.
