Instant access of a large virtual machine using a second virtual disk in a metadata file manager

A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method, the method comprising:

• obtaining, by a metadata file manager, an instant access request for instant access to a backup of a VM to execute in a production host, wherein the backup is stored in a backup storage system;
• in response to the instant access request:
• obtaining a configuration selection for the instant access of the backup;
• obtaining backup metadata associated with the backup;
• generating, at the production host, a temporary virtual disk based on the configuration selection and the backup metadata;
• generating, in the metadata file manager, a second virtual disk comprising logical blocks;
• mapping VM data stored in the backup storage system to the logical blocks in the second virtual disk;
• configuring the VM to read from the temporary virtual disk;
• and
• servicing a write request of the temporary virtual disk using the mapping of the VM data in the second virtual disk.
