Delete the data from your smartphone
Before you delete the data from your BlackBerry smartphone, consider backing up your data so that you have a copy on
your computer. If you have turned on encryption, the process for deleting all smartphone data can take up to an hour to
complete.
CAUTION: You can't stop the process for deleting all data after you start it. If you reset your smartphone, the process
continues after the smartphone restarts.
Research In Motion recommends that you regularly create and save a backup file on your computer, especially before you
update any software. Maintaining a current backup file on your computer might allow you to recover smartphone data if
your smartphone is lost, stolen, or corrupted by an unforeseen issue.

the backup file, select the Encrypt backup file checkbox. Type a password.
