Provided are a computer program product, system, and method for hypervisor agnostic interchangeable backup recovery and file level recovery from virtual disks. Data is stored for a first virtual disk that represents data in a first format and metadata for the first virtual disk in a common data format in a storage having a fixed block length. A virtual disk file represents data in a second format that allows variable size blocks. Multiple instances of the fixed block length of blocks of data for the second virtual disk indicated in the virtual disk file are read. Each instance of the read fixed block length of blocks is written to the storage in the common data format with metadata describing the format of the blocks in the second virtual disk, and can be restored to a third virtual disk in the first or second format.

Backing-up blocks from virtual disks in different virtual machine environments having different block lengths to a common data format block length

A method, apparatus and computer program product for performing database maintenance. A database running in a computer includes a first data file and a first log file. A snapshot copy of the first data file is created. Database maintenance is performed on the first snapshot copy of the first data file to produce a maintained snapshot copy of the first data file. A snapshot restore operation is performed on the database by replacing the first data file with the maintained snapshot copy of the first data file. The maintained snapshot copy of the first data file is updated according to logged transactions in the first log file which occurred after the snapshot copy of the first data file was created. In this way, a new data file is created which is both a product of the database maintenance as well as the database transactions which occurred while the database maintenance occurred.

Database maintenance using backup and restore technology

Hypervisor agnostic interchangeable backup recovery and file level recovery from virtual disks

A backup computing device detects an interruption while receiving a backup copy of a transaction log of a primary database and directs a secondary computing device to continue generation of the backup copy of the transaction log, based on the copy of the transaction log of the primary database. A primary computing device directs a secondary computing device to generate a backup copy of the data file and the primary computing device generates a backup copy of the transaction log, of a primary database. A primary computing device accesses a snapshot of a plurality of snapshots of a primary database, and generates a first portion of a backup copy of the database. The primary computing device directs a second computing device to generate a non-overlapping portion of the backup copy of the database based on a second snapshot of the plurality of snapshots.

Use of replicated copies to improve database backup performance

A method for restoring an object comprises receiving a request to restore an object. Also, the method includes outputting a representation of available backup files and receiving a selection of at least one of the available backup files. Further, the method comprises restoring at least one of the selected backup files into a temporary location and mounting at least one of the restored backup files as a server. In addition, the method includes outputting a representation of available objects from the server and receiving a selection of at least one of the available objects to be restored from the server. Also, the method includes copying one or more selected objects from the server into an Active Directory.

Individual object restore

A setup module saves disk signatures identifying cluster disks for at least one source volume to a device distinct from the cluster disks. A copy module copies data with a volume-level restore from at least one snapshot volume to the at least one source volume, overwriting the disk signatures identifying the cluster disks so that the cluster disks cannot be accessed. A reset module rewrites the saved disk signatures to the cluster disks.

Apparatus, system and method for volume-level restoration of cluster server data

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.
