Abstract: A method of backing up data including backing up, using a processor, a backup data set to a first backup data storage; storing the backup data set in a native file format in a first storage area of the first backup data storage; generating a data stream file of the backup data set in a data stream file format, the data stream file being a logical copy of the backup data set and containing metadata of the backup data set; storing the data stream file in a second storage area of the first backup data storage; and replicating, using the data stream file, the backup data set onto a second backup data storage.

Abstract: Described are techniques and systems to migrate data from a first data structure to a second data structure stored in datastores which are replicated with one another. A “hot” datastore is replicated with one or more “warm” datastores. Triggers maintain consistency between the first data structure and the second data structure. Migration may involve testing using the second data structure of the “warm” datastore. Data processed by the first data structure on the “hot” datastore is distributed via replication to the “warm” datastore, and then by a trigger to the second data structure. Data processed by the second data structure on the “warm” datastore is distributed via trigger to the first data structure, and then by replication to the “hot” datastore. Once performance of the second data structure is deemed acceptable, the “warm” datastore may be designated as “hot” and synonyms therein may direct data to the second data structure.

Abstract: A method for managing tags in a tag cloud may include receiving a tag for an object and comparing the tag to existing tags for the object. The comparing may include determining if there is a relationship between the tag and any of the existing tags.

The method may additionally include selecting one tag of the existing tags in response to the tag and the one tag being related tags. The method may further include presenting the related tags in the tag cloud. Presenting the related tags in the tag cloud may include at least one of modifying the one tag in the tag cloud, indicating the tags are related, and combining the related tags into a single tag.

Abstract: A method for determining a common sequence of statements from one or more sets of ordered statements. A data object is created that has a first group of data entries, which is created from a first sequence of statements of a first set of statements. Each data entry defines a link between a source and destination statement from the first sequence. Data entries created from a second sequence of statements of a second set are added to the first group of data entries. Each data entry from the second sequence defines a link between a source statement and a destination statement from the second sequence. A second group of data entries is created, which is determined from the first group of data entries that have an equivalent source and destination statements. The second group of data entries is stored in a database as the common sequence of statements.

Abstract: A computer-implemented system and method for generating an interest profile for a user from user generated content on existing online profiles is provided. Interest categories are maintained in a database and each interest category is associated with an initial interest index score. User generated items are selected from an existing online profile and each user generated item is associated with a weight. For each user generated item, similarity mapping is performed with each of the interest categories in the database by extracting artifacts from each user generated item, calculating an artifact similarity score for each of the extracted artifacts, obtaining a user generated item similarity score for the user generated item, and determining a current interest index score for the user generated item. An interest profile for the user is generated by applying the current interest index score to the interest category.

Abstract: Managing placement of object replicas is performed at a first instance of a distributed storage system. One or more journals are opened for storage of object chunks. Each journal is associated with a single placement policy. A first object is received comprising at least a first object chunk. The first object is associated with a first placement policy. The first object chunk is stored in a first journal whose associated placement policy matches the first placement policy. The first journal stores only object chunks for objects whose placement policies match the first placement policy. For the first journal, the receiving and storing operations are repeated for multiple objects whose associated placement policies match the first placement policy, until a first termination condition occurs. Then, the first journal is closed. Subsequently, the first journal is replicated to a second instance of the distributed storage system according to the first placement policy.

Abstract: A computing device can automatically generate a flow diagram showing statuses that objects in a system can possess, and the possible transitions between these statuses. Using snapshots of database data, the device can determine how the statuses of these objects have changed over time. The device can analyze the data to suggest which database fields likely represent object status. The device can render the flow diagram to illustrate system states at different selected times. Each rendered flow diagram can indicate, for the selected time point, the quantity of objects that possessed each status at that time, and, for a selected time interval, the quantity of objects that changed from each status to each other status during that time interval. The statuses can be represented in the flow diagram as status bubbles having sizes that are based on the quantities of objects have those bubble's statuses at the selected time point.

Abstract: Methods and apparatus related to determining points of interest based on content of one or more sources associated with a user.

Point of interest information that is related to the points of interest is provided based on the determined relevance scores.

Abstract: A server is implemented with a modified file open action, which, when a user performs the modified open, initially opens a file without locking the file. When a user indicates (either explicitly or implicitly) that the user is attempting to or intending to open the file, the file can then be locked for editing. In this way, the default action when a user requests a file is to open the file without denying other users access to the file. Then, when the user indicates that editing should occur, the lock for the file is obtained.
