  • Patent number: 12007982
    Abstract: A system for identifying and deleting records of hosts includes a local data manager. The local data manager identifies a discovery event associated with the host and a record type of record types, obtains, in response to identifying, all previously discovered records on the host associated with the record type from a host record repository, obtains discovered records associated with the record type and associated with the host, after obtaining all discovered records and previously discovered records, selects a previously discovered record of the previously discovered records, makes a determination that the previously discovered record does not match any discovered records of the discovered records and is not tagged with a soft delete tag or a hard delete tag, and in response to the determination, tags the previously discovered record with a soft delete tag, and notifies a data manager of modifications to the previously discovered records.

  • Patent number: 11836050
    Abstract: Techniques described herein relate to a method for generating synthetic full backups. The method may include obtaining a snapshot associated with a previous backup stored in a data domain; obtaining a second snapshot associated with a current state of the source data; generating a snapshot difference report using the first snapshot and the second snapshot and including a delete list, a rename list, and a copy list; storing a copy of the previous backup in the data domain; performing a delete operation on the copy based on the delete list; performing a rename operation on the copy based on the rename list; and performing a copy operation based on the copy list. In one or more embodiments, performing the delete operation, the rename operation, and the copy operation on the copy of the previous backup generates a first synthetic full backup of the source data.

  • Patent number: 11675931
    Abstract: Creating vendor-neutral data protection operations for vendors' application resources is described. Capabilities specified for data protection operations by a vendor of an application are input from a host of the application. Any capabilities specified for the data protection operations are used to create a vendor-neutral version of a data protection operation for a resource of the application. The vendor-neutral version of the data protection operation for the application resource is output to the host. A result of performing the vendor-neutral version of the data protection operation on the application resource is input from the host.

  • Patent number: 10942814
    Abstract: In an embodiment, described herein is a system and method for discovering backups of a database running on a database host, for use by a centralized backup system to validate backup compliance. A report agent executing on the database host can implement a discovery process configured to gather metadata for the backups of the database from a number of dynamic performance views of the database. The metadata is recorded in a control file of the database, and can include one or more commands used by the backup tool to create the backups. The report agent can categorize the metadata into one or more groups based on the backup commands, map backup files associated with each backup to that backup, create a backup report to describe the mapping information and additional information for each backup, and send the backup report to the centralized backup system.

  • Patent number: 10445183
    Abstract: Embodiments are described for improved management of backed up data from a client device to a storage device. The storage device may be coupled to a backup server across a network. A backup of data from an application on a client device to a storage device may fail while the backup is in progress. Systems and methods described herein can detect and remove incomplete backups. Systems and methods described herein can also scan for, and delete, save sets of a backups within a specified time interval. Systems and methods described herein can update metadata that describes existing backup data so that existing backups may be used with an updated or changed application software.

  • Patent number: 10423583
    Abstract: Described is a system and method that provides a mechanism for retrieving data from a storage system using one or more techniques. These techniques may be used in a storage configuration that stores backup or recovery data that may be retrieved by an application agent (e.g. intermediary service) in response to a query from a first device (e.g. client device). When data is stored as backup or recovery data, configurations often employ more cost effective (e.g. lower performance) storage solutions. Accordingly, in order to improve retrieval performance, the system may efficiently cache data. For example, the system may store search data from previous queries in a cache associated with the application agent (e.g. local storage) such that subsequent queries may be fulfilled, at least partially, by searching the cached search data instead of the data residing on the remote backup or recovery storage system.
