As the error says, the shares are in use with an NFS that running a Failover.Originally Posted by Oer2001
On Shares used in the NFS failover, only NFS and data Replication can be used.
So you need to stop failover to take a backup.
And backup cannot work with NFS auto Failover, this issue is in our LAB for tests, and we may have it in the future.
As only data replication is possible on shares that are in NFS failover is running( replication is like taking a backup for your data, but in the real time, sure it is recommended to have a backup too for very critical data, but you need to stop the Failover in that case).
