Managing Data Services

Configuring and implementing data replication

The DL3D appliance can be configured to automatically replicate 
data to another DL3D appliance as part of a disaster recovery plan. 
Replication is the process of sending de-duplicated data from a 
virtual tape library or NAS share on a source DL3D system to a target 
DL3D system. This process is configured on a virtual tape library or 
NAS share basis. The source system must have replication enabled. 
The target system can store replicated virtual tape library or NAS 
share data for one or more source systems. A system can be both a 
source (virtual tape library or NAS share sending replicated data) 
and target (receiving replicated data). 

IMPORTANT

!

Disable space reclamation on the target system or perform it 
manually only after replication completes successfully.

Overview of the replication process

Replication transmits data over Ethernet using TCP. The source DL3D 
can optionally encrypt the data in-line using AES-128 before sending 
it across the TCP link to the remote DL3D where it is unencrypted 
before it is stored. The DL3D uses TCP port 1062 for replication.

In DL3D 1500 and DL3D 3000 version 1.1, there are two variations of 
replication:

◆

Namespace replication (as in DL3D 1500 and DL3D 3000 version 
1.0)

With namespace replication, replication occurs at the NAS share 
or VTL level. The entire content of a NAS share or VTL replicates, 
not individual files or cartridges. The source DL3D continuously 
replicates the unique data in NAS shares or VTLs with 
de-duplication and replication enabled as de-duplication occurs. 
Replication is not complete until a namespace replication 
operation occurs. The namespace replication operation sends the 
metadata that describes the de-duplicated backup image to the 
target system. A namespace replication operation can be 
scheduled once every 24-hour period or be done manually at any 
time. The 10 most recent versions of replicated NAS shares/VTLs
