Summary

The term "Disaster Restore" refers to restoring customer data when one of their source machines has failed.

DS-System offers two choices to deal with Disaster Restore scenarios:

Disc/Tape Requests

The Disc/Tape feature includes a "disk" media type that allows you to write an "unlimited" capacity to the Disc/Tape buffer (presumably a hard disk or other similar media). Speed is maximized by multi-threaded data writing (you can select the number of threads to process the Disc/Tape request, depending on the DS-System's hardware capabilities). This means that the same request will take less time than if it were generated by the DS-System software to conventional media (e.g. tape).

When using Disc/Tape requests for Disaster Restore purposes, it is recommended that:

If the Disc/Tape directory already exists in the Disc/Tape buffer, the DS-System will prompt you to select if the Disc/Tape process should be resumed or overwritten:

Disaster Restore using a Replication DS-System

For customers that need to recover a massive quantity of data, the Disc/Tape feature may not provide a fast enough solution. For these cases, the Replication DS-System allows you to use that replica of the production DS-System (running with a Replication license), to be physically sent to the remote restore location(s).

If you already have a Replication DS-System in place to protect the production DS-System online storage, it can be used as follows:

1. Ship the Replication DS-System to the remote restore location.

2. Connect it to the remote restore LAN with the fastest possible connection speeds.

3. On each DS-Client, change the IP address to the Replication DS-System.

4. Restore at LAN speed.
