# Replication for File System Agents

With replication, you can perform incremental replication from the backup of a file system client to a destination client computer. As soon as a backup operation completes, all the data that was backed up from the source computer is replicated to the destination computer.

## Benefits of Auto Recovery Replication

You can use replication to create and maintain warm recovery sites for computers or file servers. Replication offers the following benefits:

- The impact on production servers is minimized because replication uses backup data to create replicated data. The backup operation collects file system data in a single pass, and the replication operation runs on restore infrastructure.

- Replication is hardware and software agnostic as the underlying storage being replicated and the operating system of the destination computer can be same or different from the source computer.

- You can restore data at any specific point-in-time.

The replication operation runs immediately after a backup operation to synchronize the destination computer with the source computer.

Replication is a one-way synchronization from the source to the destination. The system replicates changes made on the source computer. It does not monitor or act on changes made on the destination computer. If data is added, modified, or deleted on the destination computer, replication does not reverse those changes unless corresponding changes occur on the source computer.

## Supported Agents

- GlusterFS

- GPFS

- Lustre

- NAS

- Nutanix

- Qumulo

- UNIX and Linux

- Windows

Note

Replication is not supported for boot disks.

## Supported Replication Targets

- File systems

- NAS shares

- Azure File Shares

### Azure File Share Targets

You can replicate file system data from an on-premises file system to an Azure File Share. Azure File Share targets use file system replication workflows and are configured as file system destinations.

To use an Azure File Share as the replication target:

- Install the File System package on a virtual machine that can access the Azure File Share.

- Use the virtual machine as the target client.

- Specify the Azure File Share UNC path or NFS location as the target when you create the replication group.
