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.
