A method for performing backups. The method includes sending, via a data manager, a quiesce request to a client storage array of a client device to put the client storage array in a quiesced state. The method also includes obtaining, via a primary backup storage system, a snapshot-based backup of a storage volume of the client storage array while the client storage array is in the quiesced state. Further, the method includes sending an unquiesce request to the client storage array in response to determining that the obtaining of the snapshot-based backup is complete. Moreover, the method includes sending the snapshot-based backup from the primary backup storage system to a secondary backup storage system. In addition, the method includes generating, using the secondary backup storage system, a protection copy based on the snapshot-based backup.

System and method to enable a snapshot-based backup

A method for performing a restore operation includes identifying a full backup associated with a first client device nearest a target restore time. The method further includes identifying a set of log backups that includes a first log backup that encompasses the target restore time and all log backups between the full backup and the first log backup. The method also includes identifying a target volume to which the full backup and all log backups are to be restored, and the target volume is on a second client device separate from the first client device. Moreover, the method includes restoring the full backup and the set of log backups to the target volume. In addition, the method includes mounting, after the restoring, the target volume to a target file system. Further, the method includes performing a native client restoration mechanism to the target restore time using the target file system.

System and method to perform a restoration using snapshot-based backups

A method includes determining, by a secondary backup storage system, that a first backup operation has completed and produced a first protection copy of assets stored in a client storage array, where a primary backup storage system is used to obtain a snapshot-based backup from the client storage array and provide the snapshot-based backup to the secondary backup storage system, where the first protection copy is generated using the snapshot-based backup. The method includes identifying a second backup operation that was started before the first backup operation was started, determining that the second backup operation successfully produced a second protection copy, and generating linking metadata that links the first protection copy to the second protection copy in response to determining that the second backup operation successfully produced the second protection copy, where linking metadata is used to restore at least a portion of the assets during a restore operation.

System and method to build dependency chain for snapshot-based backups

A method for performing a backup operation includes initiating, via a client device, an archive log backup of a client storage array of the client device, generating the archive log backup on the client device, attaching a tag to the archive log backup that indicates that the archive log backup should be linked to a previously generated protection copy made using a snapshot-based backup operation, sending, from the client device to a backup storage system, the archive log backup, and linking the archive log backup to the previously generated protection copy based on the tag.
