Abstract:
Systems and methods enable a virtual machine, including applications executing thereon, to quickly start executing and servicing users based on pre-staged data blocks supplied from a backup copy in secondary storage. Substantially concurrently with the ongoing execution of the virtual machine, a virtual-machine-file-relocation operation moves data blocks from backup to a primary storage destination that becomes the virtual machine's primary data store after relocation completes. An enhanced data agent, operating in conjunction with an enhanced media agent in a storage management system, coordinates restoring the virtual machine and launching the relocation operation. The enhanced media agent pre-stages certain backed up data blocks based on predictive analysis pertaining to the virtual machine's operational profile. The enhanced media agent also pre-stages backed up data blocks for the relocation operation, based on the operation's relocation scheme. The media agent tracks read requests and maintains the contents of an associated read cache.
