主权项 1. A method of removing files associated with a virtual machine, the method comprising: creating a backup copy of data associated with a virtual machine (VM) on one or more secondary storage devices, wherein the data associated with the VM resides on a primary storage device and comprises a plurality of files associated with the VM, and wherein the backup copy comprises corresponding secondary copies of the plurality of files; analyzing, using computer hardware, metadata associated with the secondary copies of the plurality of files associated with the VM to determine which of the plurality files are eligible to be removed from the primary storage device; and in response determining that one or more files of the plurality of files are eligible to be removed from the primary storage device, for respective file of the one or more files: determining, using computer hardware, whether the respective file has been changed since a first time at which the backup copy of the data associated with the VM was created;in response to determining that the respective file has not changed since the first time, removing the respective file; andadding a file placeholder for the removed file on the primary storage device.
