Disclosed herein are various systems and methods for performing block level incremental backup operations for QCOW2 virtual disks. A first snapshot of a virtual disk is taken and used by a virtual machine at a first point in time. The virtual disk is implemented as a QCOW2 image, and taking the first snapshot causes the first snapshot to be stored in the QCOW2 image. A second snapshot of the virtual disk is taken at a second point in time. Taking the second snapshot causes the second snapshot to be stored in the QCOW2 image. One or more blocks of the virtual disk that have been modified between the first point in time and the second point in time are identified using metadata stored in the QCOW2 image. An incremental backup operation is then performed on the virtual disk by copying one or more blocks from the second snapshot to backup storage.

Block level incremental backup for QCOW2 virtual disks

A computer-implemented method for protecting deduplicated data may include (1) identifying a deduplicated data system, (2) identifying a tiered storage system for storing deduplicated objects of the deduplicated data system, (3) assigning a level of priority to at least one deduplicated object within the deduplicated data system based on at least one property of the deduplicated object, (4) selecting a storage tier within the tiered storage system for storing the deduplicated object based on the level of priority, and then (5) storing the deduplicated object within the selected storage tier. Various other methods, systems, and computer-readable media are also disclosed.
