Abstract
The present invention is a method for performing a multi-protocol scan of a NAS system by a storage virtualization system to create a multi-protocol file index. Current NAS systems may utilize two protocols, CIFS and NFS. Storage virtualization systems migrate, redirect or synchronize data between a primary and a secondary NAS. Present storage virtualization systems are designed to work with NFS or CIFS systems, but not both. The present invention enables a storage virtualization system to simultaneously or near-simultaneously operate using NFS and CIFS protocols. The present invention also provides for a multi-protocol scan of a NAS device to ensure that all data files and data file attributes are recognized and preserved during storage virtualization.
