Other requirements:

  • The source and destination shared folder or LUN must be the same provisioning type (thick or thin).

  • If the source and destination NAS devices are running incompatible versons of SnapSync, then you will be prompted to update the system firmware on one or both NAS devices.

  • If both the source and destination NAS devices are running QES, then they must run the same version of QES to ensure data consistency.

  • When using real-time SnapSync, the round-trip latency between the source and destination NAS devices must be 5ms or less. Higher latency might cause local storage write delays.
