Abstract: A changed block tracking (CBT) driver at a production host tracks, in a bitmap, changes made to a source volume of the production host since a last backup. A command is received to perform a differential backup of the source volume. A request is issued to a copy service to take a snapshot of the source volume. The bitmap is embedded into the snapshot. The snapshot is mounted on a backup proxy, different from the production host. The backup proxy retrieves the bitmap from the snapshot and conducts the differential backup of the source volume to secondary storage, thereby backing up the changes made to the source volume since the last backup according to the bitmap.

Abstract: A synthetic full backup of a source volume is retrieved, the synthetic full having been created from merging a backup chain including an incremental backup into a full backup. The full backup corresponds to a state of the source volume at a first time. The synthetic full corresponds to a state of the source volume at a second time, after the first time. A bitmap embedded into a snapshot of the source volume taken at the second time is retrieved. The bitmap identifies data from the source volume copied to secondary storage for the incremental backup. The backup chain is regenerated by copying from the snapshot the data identified by the bitmap to a regenerated incremental backup.

Abstract: A method for backing up standalone data and clustered data on a node, that includes receiving, by a backup agent, a first backup request, making a first determination that a backup process is not active, and based on the first determination, identifying a first type of data specified in the first backup request, where the first type of data is the standalone data, locating, using a first backup policy, the standalone data in the node, begin generating standalone backup data from the standalone data, receiving, by the backup agent, a second backup request, making a second determination that the backup process is active, and based on the second determination, queuing the second backup request.

Abstract: One or more embodiments of the invention relates to a method of performing a restore, by either allowing a user or administrator to choose a preferred data node for performing a restoration, or by having a data protection manager or similar component of a system dynamically choses a preferred data node for performing a restoration based on predetermined criteria. Such predetermined criteria may include each data node's load and workload as well as the type of backup that was performed to make the backup of the at least one selected asset. This will allow for more efficient restoration, while avoiding overloading when restoring assets from a backup in a data cluster.

Abstract: One or more embodiments of the invention have a cluster manager, or other related component, determine upfront which data node should perform a backup of the asset. This is achieved by running a pre-backup step, either periodically or prior to the reception of a backup request, to determine the preferred node for backup. Once the backup request is received, the cluster manager queries the preferred node, if the preferred node is still the best data node to perform the backup, then that data node performs the backup. If, however, the preferred data node no-longer is the best data node for performing the backup, the current preferred data node will signal the cluster manager with an alternative data node that is best data node to perform the backup and the cluster manager will have that alternative data node perform the backup.

Abstract: One or more embodiments of the invention improves upon the traditional method of performing a backup, by having a data protection manager or similar component of the system, determine, when a backup is requested, which backup agent should initially perform the backup. That backup agent may then determine among the other applicable backup agents, which backup types are needed and the order each backup agent performs the backup, when more than one backup agent is appropriate. This will allow for a more efficient backup, while avoiding collisions between two or more backup agents trying to simultaneously back up the same data.

Abstract: One or more embodiments of the invention may improve the operation of one or more computing devices in a cluster environment. More specifically, by mapping backups of shared volumes to a cluster client instead of individual data nodes, one or more embodiments of the invention avoid duplicative backups and/or restorations of the same shared assets by the each of the data nodes. Further, if a failure occurs to the particular node the backup may have originated from, in accordance with one or more embodiments of the invention, because the method is agnostic with regards to the individual nodes the backup may have originated from, any remaining data node can discover the backup and perform a restoration or incremental backup. This will provide better protection for the clustered nodes while requiring minimal user/administrator input.
