    摘要: Provided are a techniques for storing local versions of a data set. A first number that indicates how many local versions of the data set are to be stored in local storage given an amount of available local storage is received. It is determined whether a second number that indicates a total number of local versions of the data set that the local storage is capable of storing exceeds the first number. In response to determining that the second number exceeds the first number, the amount of local storage that is capable of storing the first number of local versions of the data set is used.

    摘要: One disclosed aspect of the present invention includes authentication and user account automation within a compute cluster for each cluster node that requires password or other credential administration. For example, a storage appliance computing system may rely on a plurality of subsystems (such as databases, storage management software, and application servers) that each have internal user accounts with associated passwords and credential keys that need to be changed at frequent intervals. Rather than requiring an administrator to manually manage all of these accounts, the presently described invention includes techniques and an authentication manager component to automatically manage, update, and refresh authentication information as required. Further, the authentication manager component may be used to perform and propagate automatic credential changes such as new sets of SSH keys or updated passwords as required within a computing system, and respond to new nodes or out-of-sync credentialing scenarios.

    摘要: Systems and methods are disclosed for providing a federated backup involving the coordination and synchronization of backup and restore operations among a plurality of hosts to ensure data consistency. A master node (backup host) acts as the initiator, coordinator, controller, and possibly as primary console for the entire backup and restore operation. All other worker application hosts and/or worker backup hosts operate as worker nodes and perform various backup and restore steps as directed by the master node. Centralized error handling aborts or recovers the entire backup operation in the event of failure on any one node. In addition, a logical view of the data is provided such that the backup can be managed as one entity, while backing up the data of each node. The backup workload may also be distributed to any other dedicated worker backup hosts (nodes) in order to minimize the impact to the production environment.

    摘要: An apparatus, system, and method are disclosed for restoring cluster server data at a volume level. A setup module opens at least one source volume of a cluster server for a volume-level restore, flushes each buffer for the at least one source volume, closes the at least one source volume, disables file system checks for the cluster disks, saves disk signatures of the cluster disks, and disables device-level checks for the cluster disks. A copy module copies data with a volume-level restore from the at least one snapshot volume to the at least one source volume. A reset module rewrites the saved disk signatures to the cluster disks, re-enables the device-level checks for the cluster disks, and resets at least one volume attribute on the at least one source volume.

    摘要: A distributed backup system for a networked computer system is disclosed such that when a data backup is created, a client backup application stores backup restore information as part of the backup data which can be interpreted by the backup application and/or backup server to direct how the remainder of the backup data needs to be restored. The backup restore information may be stored (cached) in staging directory, e.g. on the local computer system. During a backup restore process, the backup application first whether the backup restore information exist in the staging directory before requesting them from the backup server. The backup restore information may be stored in a unique location within the staging directory, e.g. a timestamp-labeled subdirectory. The backup application reconciles the staging directory to eliminate backup restore information for backup data that no longer exists on the backup server.

    摘要: A mechanism using special properties on data containers of a snapshot backup allows the snapshot backup used for a tape backup to be excluded from the policy enforcement. In addition, reconciliation of a local (client-side) backup repository and server repository bypass the snapshot backup to ensure its validity for the backup duration. If the snapshot backup is to be retained, the data container may be brought back under the domain of policy management. The policy clause may stipulate that a snapshot cannot be recycled while it is being used for a tape backup, allowing tape backups to be prioritized over subsequent snapshot backups.

    摘要: Systems and methods for managing a backup process of a database are disclosed. Typically, one or more backup logical unit numbers (LUNs) are identified in a backup management file from one or more available LUNs identified in a universe file are allocated. The backup management file comprises a plurality of data containers, each data container specifying a subset of the one or more backup LUNs capable of backing up a database comprising one or more used database LUNs. One of the plurality of the data containers are allocated for a current backup of the database as indicated in the backup management file. The backup management file is checked and updated as necessary so that the one or more backup LUNs remain available as indicated in the universe file.

    摘要: A mechanism performs a metadata image backup of a hierarchical storage management (HSM) file system. Concurrent with performing the metadata image backup of the HSM file system, the mechanism identifies a set of resident files that are not yet stored off-line in the HSM file system. The mechanism identifies immutable files within the set of resident files to form an optimized set of resident files and passes the optimized set of resident files to a traditional backup system. The traditional backup system backs up file data for the set of resident files. Responsive to detecting an inability to restore a migrated managed state of a file, the mechanism unsets an immutable bit of the file attribute, restores file data for the file using the traditional backup system, and sets the immutable bit attribute of the file.
