US Patent 12072770 Share-based file server replication for disaster recovery

A file server manager disclosed herein accesses information regarding a selected share of a source distributed file server for replication, where the selected share stores at least a portion of a namespace of storage items and is hosted by a first file server virtual machine of the source distributed file server. The file server manager accesses a mapping between virtual machines of the source distributed file server and virtual machines of the destination distributed file server and replicates the selected share to a second file server virtual machine of the destination distributed file server based on the mapping. The file server manager directs a request to read a first storage item to the destination distributed file server and directs a request to write to a second storage item to the source distributed file server while the destination distributed file server services the request to read the first storage item.
