# Inline Replication for the INFINIDAT Storage Array

The INFINIDAT Replication feature creates a replica copy of the primary snap copy of the local array on a remote array.

When you run a snap backup operation, the snapshot is created on the local array and on the remote array.

## Key Features

The key feature of the INFINIDAT Replication feature is that the primary copy and the replica copy are independent of each other and can have separate retention policies.

## Limitations

The limitations of the INFINIDAT Replication feature are as follows:

- The INFINIDAT Replication feature does not support the revert operation from the snapshot copy or from the replica copy.

- In synchronous mode, the replica copy is application consistent, except for the Microsoft Hyper-V agent. In asynchronous mode, the replica copy is crash-consistent. For the Microsoft Hyper-V agent, the replica copy is crash-consistent in synchronous and asynchronous modes.

- For inline replication, replication is performed only if the subclient on which you run the snapshot operation is associated with the replica copy.
