    摘要： A system, method apparatus, and computer readable medium for managing renewal of a dynamic set of data items. Each data item has an associated renewal deadline, in a data item management system. A renewal schedule allocates to each data item a renewal interval for renewal of the data item. On addition of a new data item, if a potential renewal interval having a duration required for renewal of the data item, and having an ending at the renewal deadline for that item does not overlap a time period in the schedule during which the system is busy, the renewal schedule is automatically updated by allocating the potential renewal interval to the new data item. If the potential renewal interval does overlap a busy period, the renewal schedule is automatically updated by selecting an earlier renewal interval for at least one data item in the set.

    摘要： Methods and systems for reading from and writing to a distributed, asynchronous and fault-tolerant storage system. The storage system includes storage nodes communicating with clients. The method includes a first client writing an object to the storage system and a second client reading the object from the storage system. For the first client, previous transient metadata relating to a previously written version of the object is retrieved and a new version of the object together with new transient metadata is stored. For the second client, a set of transient metadata from a third set of nodes amongst storage nodes is retrieved, a specific version of the object as stored on the storage system is determined, and a specific version of the corresponding object from a fourth set of nodes amongst storage nodes is retrieved. Two sets of nodes amongst all sets have at least one node in common.

    摘要： The present invention provides a method for transferring encrypted information from one storage area to other storage area wherein cryptographic data protection scheme having protection attributes are applied on the data. A crypto container having cryptographic properties represents cryptographically protected data. The attributes that have been attached to the container at the time when data is added or removed from the container determine the scheme of data protection being applied. Crypto container can be converted or serialized for storage or transmission, here the conversion spread only to the protected data parts which possibly includes crypto containers in protected form but may not the attached crypto attributes. These attributes must be stored or transmitted in another form.
