Replication refers to the process of copying or mirroring data content on a Share Disk. The Share Disk is

recreated entirely on a different NAS. The identical Share Disk uses the same name as well. The policy used to

create the replicated Share Disk can be to

mirror

or

copy

the Share Disk (see

Policy

in instructions below).

Keep in mind the following points for a Replication Backup setting.

• Replication Backup Share Disks are made to a remote NAS and must use the same name as the original

Share Disk on the source NAS.

• A NAS portal must be configured to create the replicated Share Disk.

• The remote NAS must “allow” the IP address of the Share Disk on the original NAS. See “Allow IP for

backup” on page 278

.

• Replication Backup policy choices are:

Mirror Mode

to sync added and changed files, and file deletions

are mirrored as well; or

Copy Mode

to sync added and changed files without deletion of files that were

deleted from the source Share Disk.

• Replication Backup can be used for multiple Share Disks on the remote NAS.

• A temporary Share Disk snapshot is created if snapshot is available.

• Differential and compression transmission are supported.

• Encryption is supported for transmission.

• Replication Backups can be scheduled.

• Other Replication Backup parameters include connection timeout limit, retry attempts allowed and

maximum transfer rate.
