Abstract: A system and method is disclosed for storing a block of data in a distributed data-storage system. An example method includes identifying a list of a plurality of disks in the distributed data-storage system, randomly selecting a disk from the list of the plurality of disks and adding the selected disk to a subset of disks allocated for a copyset, and continuously performing the step of randomly selecting the disk and adding the disk to the subset of disks until the copyset contains a predetermined amount of allocated disks from the distributed data-storage system.

Abstract: A method for optimizing lock detection in a change block tracker (CBT). A volume subject to the backup constantly receives writes. Therefore, it is important to divide writes that occurred before the lock and the write that occurred after the lock. The CBT is installed into kernel at the installation of the backup agent (application). The detection of changes is started at the completion of a previous snapshot. Snapshot creation request (SCR) is generated. Lock request is received by the CBT. Once the lock request is intercepted, the current changes are moved to frozen changes. The CBT processes the SCR and creates a collection of changes—i.e., snapshot with a Name. The CBT moves the current changes to the snapshot Name.

Abstract: A data backup application checks validity of data being backed up during an incremental or a full backup. In case of the file backup, the full backup checks the validity of data during the backup, because in case of data corruption the user will not have any original data since no data has been backed up yet. In case of the incremental backup, only the new files or the files that have changed compared to the last backup are now backed up. All new and modified files can be checked for validity by comparing internal format of the user files against a corresponding file format standard. If corrupted files are detected among the modified files, the user is notified.

The method may further include, in response to determining that a sector replicated from the source drive to the target drive has changed on the source drive, replicating the sector that changed on the source drive to the target drive on the target machine out-of-order. The method may also include creating an application-consistent replica version of the source machine by creating a snapshot of the source machine and replicating sectors from the snapshot to the target drive on the target machine.
