Abstract
Managing data on a storage device includes intercepting unencrypted data to be stored on the storage device, where intercepting unencrypted data is transparent to an application storing the data on the storage device and encrypting the data prior to storage on the storage device. The storage device may include a tape drive and/or a disk drive. Managing data on a storage device may also include migrating data from a first storage location to a second storage location. The first storage location may be the same as the second storage location or the first storage location may be different from the second storage location. The unencrypted data may be intercepted during migration. Managing data on a storage device may also include decrypting data read from the storage device.
Claims20
A method of managing data on a storage device, comprising:
- intercepting unencrypted data to be stored on the storage device, wherein intercepting unencrypted data is transparent to an application storing the data on the storage device;
- and
- encrypting the data prior to storage on the storage device.
Computer software, in a computer readable medium, that manages data on a storage device, comprising:
- executable code that intercepts unencrypted data to be stored on the storage device, wherein intercepting unencrypted data is transparent to an application storing the data on the storage device;
- and
- executable code that encrypts the data prior to storage on the storage device.
