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.
