Abstract: A database server receives a request from a client application for performing a data transaction on persistent data storage. The request is sent to a set of replication servers. An acknowledgement for the request is received from each replication server, including a start sequence number and an end sequence number for data that is stored in local cache of the replication server, and a latest committed sequence number for data that was written to the persistent data storage by the replication server. A maximum value of latest committed sequence numbers received from the set of replication servers is determined. For each replication server, it is examined whether there is a gap between the start sequence number for data stored in local cache and the maximum value of the latest committed sequence numbers. Based on the examining, it is determined whether there is an occurrence of loss of data.

Abstract: Aspects include systems and methods for synchronizing a remote datastore that includes files and data for use by an application on a remote device, which can be represented on the device in a device-specific format, while the remote data store can have a different data representation, such as a relational database or object graph data model. A server can maintain a unique row identifier for each row in all synchronized tables and an update log table that has rows with the unique row identifiers for changed rows (inserted, updated or deleted), for each insert, update, or delete operation and a current update version that reflects the last change to that row. An update request from a device can comprise identifiers for a (sub)set of the data. The update log table can be used to prepare an update package containing this data.

Abstract: An on-disk structure of a file system has the capability to efficiently manage and organize data containers, such as snapshots, stored on a storage system. A multi-bit, monotonically increasing, snapshot identifier (“snapid”) is provided that represents a snapshot and that increases every time a snapshot is generated for a volume of the storage system. The snapid facilitates organization of snapshot metadata within, e.g., a data structure used to organize metadata associated with snapshot data. In the illustrative embodiment, the data structure is a balanced tree structure configured to index the copy-out snapshot data blocks. The snapid is also used to determine which blocks belong to which snapshots. To that end, every block that is used in a snapshot has an associated “valid-to” snapid denoting the newest snapshot for which the block is valid. The oldest snapshot for which the block is valid is one greater than the valid-to field of the next older block at the same file block number.

Abstract: A computer-based system creates a data object by preparing a data structure for the data object in a database and processes the data object at different processing stages each associating a different workflow state with the data object. The system can take and store automatically a snapshot of the data object, prior to a workflow transition of the data object from a first workflow state to a second workflow state, respectively associated with the snapshot and with the data object. The system also creates a unique locating reference for the snapshot based on a unique locating reference created previously for the data object. When the unique locating reference for the data object is received, controlled access to the data object and the snapshot is provided. Based on one unique locating reference, multiple states of the data object can be easily and efficiently made available concurrently to a user.

Abstract: A computer that is programmed with collaboration software receives a change to be made to an object that can be of any type among several predetermined types such as message, document, contact, discussion and meeting. The object is represented as an aggregate of identifiable parts shareable by users, including at least a content part, a lock part, and an access-control part. Each version of the object is represented by a set of identifiers of these parts. In response to receipt of information identifying the change, the computer automatically identifies a specific part to be changed from among multiple parts of the object. Thereafter, the computer automatically creates a new instance of the specific part which contains the change as per the received information. The computer automatically stores a new version of the object as a new set that includes a new identifier of the new instance of the specific part.

Abstract: A computer that is programmed with collaboration software receives a new value of an attribute (or property or characteristic) which is specific to a label (or tag or category) as applied to an object managed by the computer. The computer does not use the new value to overwrite a corresponding old value in existing metadata. Instead, the computer is programmed to hold the new value in an incremental label application for the object. The computer is further programmed to respond to a request for the object's label application, by retrieving the incremental label application, and a full application of said label to said object. The computer uses attribute values in the incremental label application to update corresponding attribute values in a copy of the full label application, in a time sequence based on the time of creation of incremental label applications, thereby to generate a current label application.

Abstract: Provided herein are systems and methodologies for highly efficient restoration in a network-based backup system. As described herein, differential-based analysis can be utilized such that a new complete differential is calculated based on signatures and/or other information relating to a given item to be restored prior to retrieving backup data. Based on the differential, only blocks determined to be unique between the current version of the item and the desired version are transmitted, which can then be merged with non-unique locally present blocks to obtain the fully restored version of the item. Further, a hybrid architecture can be employed, wherein signatures and/or data are stored at a global location within a network as well as one or more local peers. Accordingly, a backup client can obtain information necessary for restoration from either the global location or a nearby peer, thus further reducing latency and bandwidth consumption.

Abstract: Presented herein are methods of continuously verifying data and repairing errors introduced during replication. In a particular embodiment, a primary data store sends out information sufficient to create a checkpoint together with a checksum for the data being verified at that checkpoint. At the secondary data store, a checkpoint is created in accordance with the checkpointing information, and a checksum is calculated over the indicated data at the created checkpoint. If the calculated checksum disagrees with the received checksum, additional checksums are calculated over subranges of the indicated data and compared with corresponding checksums over the data at the primary data store. The checksums at the primary data store may be requested from the primary data store or calculated locally based on the received overall checksum. Once an erroneous entry is identified, it can then be re-replicated from the primary data store to restore data consistency.

Abstract: A method for updating and formatting a local file is described. An update file, having a newer version of the local file, is accessed from a server over a network and a list of new hash values corresponding to data blocks of the update file is retrieved. Divisions between the data blocks are located when a value of a rolling checksum reaches a particular value, the data blocks being of variable size. New hash values of the update file are compared with local hash values of the local file. For each of the new hash values not having a matching local hash value, the corresponding data block is downloaded from the server and written to a new file. For each of the new hash values having a matching local hash value, the corresponding block is copied from the local file to the new file.
