media storage is deleted. 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

About compression

Compression is designed to reduce the size of your BlackBerry smartphone data while maintaining the integrity of that
data. When compression is turned on, your smartphone can compress your data, including messages, contacts, calendar
entries, tasks, and memos. You should keep compression turned on.
If both compression and encryption are turned on, your smartphone compresses smartphone data before encrypting it.

About file encryption

File encryption is designed to protect files that you store on your BlackBerry smartphone and on a media card that can be
inserted in your smartphone. You can encrypt the files on your smartphone and on your media card using an encryption
key that your smartphone generates, your smartphone password, or both.
If you encrypt the files using an encryption key that your smartphone generates, you can only access the files on your
media card when the media card is inserted in your smartphone. If you encrypt the files using your smartphone password,
you can access the files on your media card in any smartphone that you insert your media card into, as long as you know
the password for the smartphone.
