The present disclosure is directed to a method and system for encrypting files based on security rules. In accordance with a particular embodiment of the present disclosure, a request to store a file on a storage device is received. At least one security parameter associated with a security profile of the file is identified. It is determined whether to encrypt the file by applying at least one security rule to the security parameter. The security rule includes selection criteria. The file is encrypted if the security rule indicates the file should be encrypted. The file is stored on the storage device.

Method and system for encrypting files based on security rules

According to one embodiment, a data storage system includes a storage medium coupled to a compression appliance. The compression appliance is operable to selectively compress data that is stored on the storage medium. The compression appliance selectively compresses the data according to a lower compression threshold and an upper compression threshold such that a useful compression level is achieved while balancing processor loading.

System for compression and storage of data

The present invention is directed to a method and system for intercepting transactions for encryption. In accordance with a particular embodiment of the present invention, an application for a storage device is monitored. A transaction for the storage device is intercepted. An encryption request within the transaction is identified. Performance of the transaction is emulated by performing the encryption request in a predetermined exit point of the application.

Method and system for intercepting transactions for encryption

Systems and methods are provided for encrypting data, generating encryption keys, and generating encryption indicators. The encryption indicators may be stored on a storage medium in a location separate from the location of stored encrypted data. The encryption indicator includes information indicative of the encryption key used for encrypting and decrypting the data. In one example, the storage medium is a tape, and the encryption indicator is stored in the user header label of the tape.

System and method for data encryption keys and indicators

Systems and methods are provided for encrypting data without regard to applications writing the data to, or reading the data from, encrypted data storage devices. An operating system intercept detects information indicating that a file will be encrypted and, in respond, sets device-level flags indicating encryption and also establishes one or more encryption keys to be used in the encryption process. A second intercept detects an input/output event and, in response, calls an encryption application to encrypt (or decrypt) the data before it is written to (or read from) the data storage device.
