A method, article of manufacture, and apparatus for backing up data. In some embodiments, this includes backing up an object to a repository, segmenting the object into a plurality of sub-objects, and assigning a priority to a sub-object. Segmenting the object may include segmenting the object based on file access patterns. Assigning a priority may include assigning a high priority based on file access patterns, or based on policy, among others.

Prioritized backup segmenting

A method, article of manufacture, and apparatus for recovering data. In some embodiments, this includes selecting an object to be recovered, recovering sub-objects of the object based on the priorities assigned to the sub-objects, and reprioritizing the sub-objects based on an application's I/O during recovery. In some embodiments, reprioritizing the sub-objects the sub-objects includes assigning a lower priority to the sub-objects when an application has completed I/O on the object. In some embodiments, recovering sub-objects includes recovering sub-objects to a remote location.

Dynamic prioritized recovery

A user-defined, structured input which identifies a column in a database and includes an active input associated with the column is received via a UI. A format-related, context-sensitive rule which applies to the active input is determined including by determining an expected format for the active input based at least in part on the format of the column in the database. Guidance associated with satisfying the rule is provided in real time via the UI. This includes displaying format assistance associated with the rule (by identifying the expected format and/or automatically configuring the UI so that the active input has a format which matches the expected format) and/or displaying format validation associated with the rule, including by indicating whether the format of the active input matches the expected format.

Method to input content in a structured manner with real-time assistance and validation

A method, article of manufacture, and apparatus for processing data. In some embodiments, this includes analyzing a first container at a block level, determining a first level of granularity based on the analysis of the first container, based on the first level of granularity, identifying a first set of data objects, storing metadata of the first set of data objects in a recovery catalog, based on the first set of data objects, identifying a second container, analyzing the second container at a block level, determining a second level of granularity based on the analysis of the second container, based on the second level of granularity, identifying a second set of data objects, storing metadata of the second set of data objects in the recovery catalog, wherein the recovery catalog is stored in a storage device.

Post backup catalogs

Techniques to search logs that contain a massive number of entries are disclosed. In various embodiments, logs are pre-scanned incrementally to identify logs of interest. A log is identified as a log of interest based at least in part on a determination that the log satisfies a symptom definition associated with a symptom. A symptom pre-scan result is generated for those logs of interest that satisfy the symptom definition. The symptom pre-scan result is stored in a searchable pre-scan result data store.

Method and system to search logs that contain a massive number of entries

A method, article of manufacture, and apparatus for accessing data during data recovery. In some embodiments, this includes sending an I/O request from an application to an object, wherein the object is being recovered, establishing an I/O intercept, intercepting the application's I/O request with the I/O intercept, and redirecting the I/O request based on the status of the object's sub-objects.

Data access during data recovery

A method, process, and system for multi-tier resale is discussed here. Acceptance proxies may be distributed to downstream resellers and customers. The acceptance proxies may be registered with a producer who provides a service. The acceptance proxies may be registers directly, or anonymously. Escrow services may ensure each party has fulfilled its contractual obligations before access to the service is granted.

Licensing model for tiered resale

Consensus-based remediation of offerings' problems is described. A system can receive an indication of an offering's problem. The system identifies possible remediations for the offering's problem from on-line sources of remediations. The system determines an efficacy for each possible remediation. The system arranges each possible remediation in order based on its efficacy. The system outputs the possible remediations based on their order. The system can store the ordered possible remediations into a repository.

A method, article of manufacture, and apparatus for recovering data. A method for recovering data includes selecting an object to be recovered, recovering sub-objects of the object based on the priorities assigned to the sub-objects, and reprioritizing the sub-objects based on an application's I/O during recovery. A method for recovering data includes reprioritizing the sub-objects the sub-objects includes assigning a lower priority to the sub-objects when an application has completed I/O on the object. A method for recovering data includes recovering sub-objects includes recovering sub-objects to a remote location.

A method, article of manufacture, and apparatus for backing up data. The method for backing up data includes backing up an object to a repository, segmenting the object into a plurality of sub-objects, and assigning a priority to a sub-object. Segmenting the object may include segmenting the object based on file access patterns. Assigning a priority may include assigning a high priority based on file access patterns, or based on policy, among others.

A method, article of manufacture, and apparatus for protecting data. In some embodiments, this includes taking a snapshot of a virtual machine, parsing the virtual machine to determine a header section and a file system, indexing the virtual machine based on the parsing, storing the index in a storage device, and storing the snapshot in a deduplicated data storage device.

Efficient backup of virtual data

Intrinsic system metadata is received from the plurality of computer systems, wherein the intrinsic system metadata includes operational data reported by individual systems in the plurality of computer systems. The intrinsic system metadata is normalized to identify a representative. Individual outlier systems are identified by comparing operational data to the representative.

Categorizing systems at scale using system attributes

A system for bug discovery using event reports comprises an interface and a processor. The interface is configured to receive symptom data extracted from event reports from a user system. The symptom data is stored in a symptom database. The symptom data comprises one or more symptoms each with a corresponding symptom occurrence time. The processor is configured to compose one or more SQL queries using one or more bug definitions and determine an existence of one or more bugs of the user system based at least in part on a result of querying the symptom database using the one or more SQL queries.

Set-based bugs discovery system via SQL query

A system for discovering bugs comprises an input interface and a processor. The input interface is configured to receive a bug definition. The bug definition includes a set operator with a time constraint and one or more set operands. The input interface is configured to receive an event log. The processor is configured to determine a list of bug occurrences using the bug definition and the event log.
