摘要： A method for determining volume coherency is disclosed herein. Upon completing a first write job to a volume partition, the method makes a copy of a volume change reference (VCR) value associated with the volume. The VCR value is configured to change in a non-repeating manner each time content on the volume is modified. Prior to initiating a second write job to the volume partition, the method retrieves the copy and compares the copy to the VCR value. If the copy matches the VCR value, the method determines that a logical object on the partition was not modified between the first and second write jobs. If the copy does not match the VCR value, the method determines that the logical object on the partition was modified between the first and second write jobs. A corresponding system and computer program product are also disclosed herein.
摘要翻译：本文公开了一种用于确定卷一致性的方法。完成对卷分区的第一次写入作业后，该方法将创建与卷相关联的卷更改引用（VCR）值的副本。每次修改卷上的内容时，将VCR值配置为以不重复的方式进行更改。在向卷分区启动第二次写入作业之前，该方法将检索副本并将该副本与VCR值进行比较。如果复制与VCR值匹配，则该方法确定在第一和第二写入作业之间没有修改分区上的逻辑对象。如果副本与VCR值不匹配，则该方法确定分区上的逻辑对象在第一个和第二个写入作业之间已被修改。本文还公开了相应的系统和计算机程序产品。

摘要： A method, system and program are provided for enabling selective access to multiple users' encrypted data in a single storage cartridge. A unique, derived key is generated for each user's data by performing cryptographic operations on a combination of a common base key and metadata related to the data to be encrypted (e.g. its total block count). The base data key is wrapped with one or more encryption keys to form one or more encryption encapsulated data keys (EEDKs). The base key and the derived key are wrapped to create a session encrypted data key (SEDK), which along with the EEDKs, are conveyed to the tape drive, where the SEDK is decrypted. The EEDKs are then stored in one or more places on the storage cartridge. The base key and the derived key are used to encrypt a predetermined user's data, with the derived key stored on the cartridge with the encrypted data. The encrypted data may be subsequently decrypted by retrieving the EEDK and decrypting it with a decryption key to extract the base data key. The extracted base data key can then be used with other information to calculate the derived key. Once calculated, the derived key is used to decrypt its associated encrypted data.

摘要： A method, system and program are provided for enabling access to encrypted data in a storage cartridge by separately wrapping the data key used to encrypt the data with separate encryption keys (e.g., a public key from a public/private key pair) to form encryption encapsulated data keys (EEDKs) that are stored on the storage cartridge along with the encrypted data. With multiple EEDKs stored on the cartridge, a multi-user transport mechanism is provided where each user can access and decode the encrypted data by retrieving and decrypting an EEDK with a decryption key (e.g., the private key from the public/private key pair) to extract the underlying data key, and then using the extracted data key to decrypt the encrypted data.
