NexentaStor auto-cdp service provides remote mirroring capability.
The service replicates appliance's volumes between two different appliances in real time, at a block level. Conceptually, the service performs a function similar to local disk mirroring scheme of RAID 1 except that in the case of auto-cdp this is done over an IP network.
NexentaStor auto-cdp service is based on Sun StorageTek Availability Suite and does not utilize ZFS. NexentaStor data replication services address Disaster Recovery, Continuous Data Protection, and other emerging technology solutions as every aspect of business goes digital, and must be protected, preserved, or potentially expired as required. NexentaStor appliance can also be used just as a tool or conduit, providing all the data replication services when both the source and targets are remote.
AutoCDP NMS service is available as a commercial plugin for NexentaStor Enterprise Edition.
To install, run:
nmc$ setup plugin install autocdp
Or, you can view, install and uninstall the NexentaStor extension module using appliance's web GUI, as shown below:
Confirming the action:
Before installing the Auto-CDP plugin, please make sure that data volume (that you intend to replicate) exists, both appliances are SSH-bound and networking connectivity is properly setup. Please refer to NexentaStor User Guide for details on how to create data volume, setup SSH and networking connectivity.

Note:
Even if your data volume is unused, the initial syncing will take significant amount of time necessary for block-level sector-by-sector transfer of all its (unused) blocks over the IP network.
