Cleaning up disk storage

You must clean up your disk storage before you back up your data and eventually perform your upgrade. Cleaning up your disk storage is important for these reasons:

• It shortens the amount of time it takes you to back up your data.
• It might improve performance.
• It releases additional storage space.
• If you need to perform an unplanned recovery from media, the recovery time is shorter.
