  • Patent number: 10976952
    Abstract: A remote agent for providing backup services to applications includes a persistent storage and a backup manager. The persistent storage stores backup policies for the applications. The backup manager identifies an application of the applications for providing the backup services; generates an application backup template based on a backup policy of the backup policies for the application; sends the generated application backup template to a production host that hosts the application; and makes a determination that the backup policy has been triggered. In response to the determination, the backup manager initiates a native data extraction from the application using the application backup template to obtain a native data dump; stores the native data dump in backup storage; and indexes the stored native data dump as a backup.

  • Patent number: 10929040
    Abstract: In a half-compressed RAID 1 system a first copy of a data set is maintained in an uncompressed state and a second copy of the data set is maintained in a compressed state, where corresponding compressed and uncompressed blocks are stored on different physical devices. The result is RAID 1 reliability with storage space consumption similar to RAID 5-3+1. Compression striping in which the compressed and uncompressed data is distributed across two or more storage devices can be used to reduce data access response time. Further, delayed compression can be used to reduce the time required to perform WRITE ops. Compression may also be performed based on resource availability or storage tier hierarchy.

  • Patent number: 10915503
    Abstract: A space allocator in a file management system maintains and uses one or more offsets and a stored value of the largest space skipped on previous scans to increase the efficiency of scans for available space in a file system space map. When the space allocator determines a current allocation request is greater than the largest space skipped in the previous scan, a last allocated offset can be used to begin scanning to reduce the portion of the map to scan in order to find available space. When the space allocator determines the current allocation request is less than or equal to the largest space skipped in the previous scan, a first available offset can be used to begin scanning for an appropriate unused space.

  • Patent number: 10908826
    Abstract: A processor can determine that a set of the memory cells is controlled by signals from a first portal. The processor can determine a function of a second portal in a relationship between the first portal and the second portal. The processor can cause, in response to a determination that the function of the second portal is a specific function, a memory control circuitry to be configured so that a subset, of the set, is controlled also by signals from the second portal. The processor can determine a function of a third portal in a relationship between the first portal and the third portal. The processor can cause, in response to a determination that the function of the third portal is the specific function, the memory control circuitry to be configured so that the subset, of the set, is controlled also by signals from the third portal.
