Abstract
Examples of systems described herein include a virtualized file servers. Examples of virtualized file servers described herein may support disaster recovery of the virtualized file server. Accordingly, examples of virtualized file servers may support metadata fixing procedures to update metadata in a recovery setting. Examples of virtualized file servers may support hypervisor-agnostic disaster recovery.
Claims21
At least one non-transitory computer readable storage medium encoded with executable instructions which, when executed by at least one processor of a system, cause the system to perform operations comprising:
- replicating a share of a first virtualized file server (VFS) located at a first site to update a second VFS located at a second site, each VFS of each site including a respective plurality of file server virtual machines (FSVMs) hosted on a respective plurality of host machines, each of the FSVMs presenting a namespace of storage items including the share;
- and
- in response to disaster recovery of the first VFS, activating the second VFS to recover the share for at least a portion of the first VFS.
A method comprising:
- replicate a share of a first virtualized file server (VFS) located at a first site to update a second VFS located at a second site, each VFS of each site including a respective plurality of file server virtual machines (FSVMs) hosted on a respective plurality of host machines, each of the FSVMs presenting a namespace of storage items including the share;
- and
- in response to disaster recovery of the first VFS, activate the second VFS to recover the share for at least a portion of the first VFS.
A system comprising:
- a first virtualized file server (VFS) located at a first site, the first VFS comprising a first plurality of file server virtual machines (FSVMs) hosted on a first plurality of host machines, each of the first FSVMs configured to present a namespace of storage items including a share;
- a second VFS located at a second site, the second VFS comprising a second plurality of FSVMs hosted on a second plurality of host machines;
- wherein the first VFS is configured to replicate a share to the second VFS;
- and
- wherein the second VFS is configured to be activated responsive to disaster recovery of the first VFS to recover the share.
