Disaster Restore Solutions (for customers)
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
- For more information and instructions, see "Disc / Tape Restore".
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:
- You create an "unlimited" media type to use for the Disc/Tape buffer, and
- You process the request (write to buffer) using multiple threads (the number of threads depends on existing activities, number of CPUs, etc.).
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:
- "Resume" will try to continue based on the records included in the catalog file. (If the resume fails, the DS-System will perform an overwrite.)
- "Overwrite" will force the DS-System to rewrite all the data in the Disc/Tape buffer for the required backup set.
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.
