The system further automatically categorizes the unprotected virtual machines, identifies those unprotected virtual machines that remain uncategorized, and applies a default backup policy to the uncategorized and unprotected virtual machines to provide protected virtual machines.

Abstract: Methods, systems, and computer storage media for providing log files using logging system operations in a logging system. The logging system operations support memory mapping log files and asynchronously managing file operations. The logging system operations support selectively mapping segments of log files during write operations. The logging operations also support performing file operations (e.g., closing, opening, deleting and serializing files) advantageously as background processes. Selective memory mapping specifically includes incrementally mapping new segments of a log file up to a predetermined log file size limit. The logging operations support processing spare files using spare file memory mapping. A spare file replaces an existing log file to continue writing logging data using the spare file.

In other cases, file fetching and restoration may be performed by a storage appliance using index node-based mappings for multi-link files that provide mappings between index node identifiers (e.g., inode numbers) for the multi-link files on a primary system and hard link paths for storing the file contents of the multi-link files on a storage appliance used for backing up the primary system.

Abstract: Virtualization sprawl can lead to virtual machines with no designated periodic backup. If the data associated with these unprotected virtual machines is not backed up, it cannot be restored if needed, leading to system failures. A data storage system identifies and protects the unprotected virtual machines. For instance, the system compares a list of virtual machines with a list of computing devices having a designated backup policy in the data storage system and determines which of the virtual machines are unprotected. The system further automatically categorizes the unprotected virtual machines, identifies those unprotected virtual machines that remain uncategorized, and applies a default backup policy to the uncategorized and unprotected virtual machines to provide protected virtual machines.

Abstract: According to examples, an apparatus may include a processor that may automatically restore a backup copy from a remote backup storage system to a user device without a user request to do so. For example, the apparatus may, at various times without user intervention, determine whether a restoration of a backup copy of local data is to be performed based on various criteria for automatically restoring the backup copy without a user request to do so. Based on satisfaction of the criterion, the apparatus may restore the backup copy to the original location of the local data (to immediately replace the local data) and/or to a temporary location accessible to the apparatus (such as via onboard storage) from which the backup copy may replace the local data at a later time (such as on-demand).

The processor may generate a first set of instructions for taking a first snapshot of a variable storage space associated with the marked data when entering the scope and a second snapshot of the variable storage space when exiting the scope. The processor may generate a second set of instructions for comparing the first and second snapshots to determine a usage amount of the variable storage. The processor may generate a third set of instructions for performing an action in response to the usage amount of the variable storage space exceeding a threshold. The processor may compile the code into an executable.

Abstract: An efficient method for generating asset backup scheduling plans. Within a data protection environment, at least two service level metrics may be observed—a recovery point object (RPO) and a recovery time objective (RTO). In order to meet acceptable values for these metrics, on par with established service level agreements, infrastructure employed throughout the data protection environment, as well as the scheduling of asset backup operations, tend to grow in complexity. To address service distributions potentially emerging from the aforementioned complexities, the disclosed method proposes a heuristic approach to generating asset backup scheduling plans, which consider factors such as backup device limitations, RPO violation minimization, asset usage, and asset prioritization.

The differences correspond to the one or more changes to the file system data between the requested backup version and the last backup snapshot. One or more data blocks corresponding to the one or more changes to the file system data since the last backup snapshot and one or more data blocks corresponding to the one or more changes to file system data between the requested backup version and the last backup snapshot are provided to a primary system.

Abstract: Systems and methods for storage pruning can enable users to delete, edit, or copy backed up data that matches a pattern. Storage pruning can enable fine-grain deletion or copying of files from backups stored in secondary storage devices. Systems and methods can also enable editing of metadata associated with backups so that when the backups are restored or browsed, the logical edits to the metadata can then be performed physically on the data to create a custom restore or a custom view. A user may perform operations such as renaming, deleting, modifying flags, and modifying retention policies on backed up items. Although the underlying data in the backup may not change, the view of the backup data when the user browses the backup data can appear to include the user's changes. A restore of the data can cause those changes to be performed on the backup data.

Abstract: In addition to caching I/O operations at a host, at least some data management can migrate to the host. With host side caching, data sharing or deduplication can be implemented with the cached writes before those writes are supplied to front end storage elements. When a host cache flush to distributed storage trigger is detected, the host deduplicates the cached writes. The host aggregates data based on the deduplication into a “change set file” (i.e., a file that includes the aggregation of unique data from the cached writes). The host supplies the change set file to the distributed storage system. The host then sends commands to the distributed storage system. Each of the commands identifies a part of the change set file to be used for a target of the cached writes.

Abstract: A new metadata field is described that can be used with requests to store a volume in a block storage service. The metadata field is a parameter included in the request and is a logical association identifier that associates the volume to be stored with other already-stored volumes. Using this logical association identifier, the block storage service can ensure that all volumes having the same identifier are sufficiently spread across server computers. The logical association identifier can be a workload identifier indicating that the volumes are all from a same relational database, application, etc. Target customers are defined as customers that request an action of a service within a cloud environment and the service then makes a request to the block storage service. In this case, the service is a customer of the block storage service and it can pass the target customer identifier as the logical association identifier.
