  • Publication number: 20230409446
    Abstract: Communications are exchanged with a copy service of a host to identify writers associated with the copy service. The identification includes a type of a writer as being a system or application writer. Writers identified as system writers are added to a list of writers that should participate in a backup operation. For writers identified as application writers, components of an application writer are iterated through to determine whether a component of the application writer has a name or logical path that includes a name of a system service. When any component has the name or logical path that includes the name of the system service, the application writer is promoted to be of type system writer by adding the application writer to the list of writers that should participate in the backup operation. Components of each writer listed in the list of writers are backed up.

  • Publication number: 20230409436
    Abstract: A data structure is generated to store information about a set of writers associated with a copy service. The information is gathered from the copy service and populated into the data structure. The information includes names of the writers, writer types as being system or application writers, and system writer subtypes as being one of bare metal recovery (BMR) writers or system state recovery (SSR) writers. The data structure is reviewed to determine whether a particular writer should participate in the backup. Based on the review, a list is generated including a subset of the participating writers. Instructions are issued, via the copy service, for the writers in the list to prepare for creation of a snapshot. Upon creation of the snapshot, data is backed up from the snapshot to secondary storage.

  • Patent number: 11836046
    Abstract: Writers participating in a backup are identified. A mapping is generated between the writers and associated files. The mapping includes file properties. The mapping is initialized by tagging the writers with a full backup tag. A base backup copy of the writers is created by conducting a full backup of each writer tagged with the full backup tag. At a current backup operation after creating the base backup, a list of current files that will participate in the current backup operation is generated. The list of current files is compared against the files in the mapping to determine whether a particular writer associated with a current file should be tagged with the full backup tag or an incremental backup tag. The particular writer is tagged with the incremental backup tag when file properties associated with the current file have changed.

  • Patent number: 11829630
    Abstract: Described is a system (and method) for providing multiple types of granular delete operations for a cloud-based object storage. The system may include a server that acts as an intermediary between a client device and an object storage that stores client data. The server may allow a client to perform a hard delete (or permanent) delete and a soft delete. The server may perform a specialized processing to synthetically create the soft delete feature using a permanent object delete operation provided by the object storage. The specialized processing may include manipulating retention periods associated with objects depending on whether the object is subject to a hard delete or a soft delete. As a result, the server may provide the ability for clients to perform a soft delete at an object level using existing storage level APIs that do not directly support such a feature.

  • Patent number: 11809280
    Abstract: Described is a system for synchronizing expiration times for incremental backup data stored on a cloud-based object storage. More particularly, the system may provide a layer of intelligence when updating the expiration times associated with backup data to ensure that a full recovery of the client data to a point-in-time of any incremental backup may be performed. To provide such a capability, the system may maintain specialized metadata identifying expiration times for objects and a list of objects required to perform a full recovery to a point-in-time for each of the performed backups (e.g. full or incremental). The system may access this metadata to identify which objects stored by a previous backup are still referenced by a subsequent backup. Based on the identified objects, the system may synchronize object expiration times to ensure objects are not prematurely deleted from the object storage.
