About disc/tape restores
For each disc/tape request, you can generate the restore data in disc/tape restore format for restore via the DS-Client. DS-System copies the requested data to a buffer path. From that path, you can copy or burn the data to whatever media you choose to support for your customers (CD, DVD, hard disk drive, or tape).
NOTE: A disc/tape request (initiated from either the DS-Client side or the DS-System side) will lock the corresponding backup set until the request is successfully completed (written to buffer) or deleted from the Disc/Tape Orders list.
If a customer needs to restore their entire LAN (or any large quantity of data), this may take a long time (even with a high bandwidth connection). It may be faster to write the required data to local media connected to the DS-System. Then you can ship the media to the DS-Client’s physical location where it can be attached as a local drive or restored via a LAN connection. This can be accomplished using the disc/tape feature.
There is a disk media type that allows you to write an unlimited capacity to the disc/tape buffer (presumably for a hard disk or other similar media). Speed is maximized by multi-threaded data writing where you select the number of threads to process the disc/tape request.
When using disc/tape requests for disaster restore purposes, you should:
• Create an unlimited media type to use for the disc/tape buffer.
• Perform the write to buffer process using multiple threads. The number of threads to use 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.
