How to control mutual access between network segments
On AR routers, you can configure advanced ACL and ACL-based traffic classifiers to control mutual access between users on different network segments.

What Is the Difference Between Backup and Replication?

A backup operation stores data of an EVS disk to the local backup storage.

A replication operation copies backups (generated in backup operations, used to restore EVS disk data), and stores the backup copies to the remote backup storage. When the local backups are corrupted, the remote backup copies can be used instead to restore EVS disk data.
