Configuring the disc/tape media
Before you configure the disc/tape media, you must ensure the DS-System has sufficient buffer space where the files will be copied and a disc burner or tape writer, if applicable. The DS-Client must have the Disc/Tape tool enabled.
To configure the disc/tape media:
1. On the Disc/Tape menu, click Media.
2. In the Disc/Tape Media dialog box, do one of the following:
• To add a new media type, click Add.
• To modify a media type, select the media, and then click Modify.
NOTE: To delete a media type, select the media, and then click Delete.
3. In the Media Name box, type a name for the media.
4. In the Media Type box, select the type of media.
5. Beside Media Size, select the size of the media from the following options:
• Limited size – Disc/tape requests are written into buffer folders that will accommodate the size of the media.
• Unlimited size – Disc/tape requests are written to a single buffer location, but can take advantage of multiple write threads for faster performance.
NOTE: The media size option is available only for the disk media type.
6. In the Total Capacity (MB) box, type the capacity of each unit of the media type.
7. In the Guard Size (MB) box, type the buffer capacity that is subtracted from the total capacity of the media unit for the purpose of calculating how many units are required.
8. In the Block Size (Bytes) box, type the size of the smallest block the disk controller can read or write.
NOTE: Do not change this value unless you have a requirement to do so.
9. Click OK.
You can now use the disc/tape option from the DS-Client to create disc/tape snapshots at the backup level from the DS-System. For more information, see the DS-Client User Guide.
