A replication operation service migrates data from a source volume having a source file system type to a destination volume having a destination file system type, where the source file system type may be different from the destination file system type. The replication operation is completed without interrupting the operations of a client device in the system. A stable copy of the source file system is generated on the source volume. A file system agnostic representation of a portion of the data in the source volume is generated from the stable copy. The representation is transmitted to the destination volume where it is converted to conform to the destination file system type.

File system agnostic replication

A system and method that provides users of network data storage systems with the ability to gain the advantages of a clustered storage server system, in which volumes stored on multiple server nodes are linked into a virtual global hierarchical namespace, without first having to migrate their data to the clustered storage server system. The system employs an extended virtual global hierarchical namespace that allows client systems to access, via the extended global namespace, volumes stored on the clustered storage server system and on one or more storage servers that are remote from and do not constitute a part of the clustered system. The extended global namespace can also be employed to perform migration of volume data among the multiple nodes of the clustered storage server system and the remote storage servers.
