Quantum LTO-2 manual Configuring for SCO Open Server, Using the command

Chapter 6 UNIX Settings

Configuring for SCO Open Server 5.0.x

8Exit SMIT.

Note: We suggest using the AIX commands .backup and .restore when transferring data to and from the LTO-2 Half- Height Tape Drive. These commands transfer data more quickly than other commands such as tar and cpio.

•For cpio we suggest a blocking factor of 128.

•For tar we suggest using the .N option and a factor of 128.

•Some older systems with poor video controllers may experience a reduction in performance when using the .v option, which prints the path names on the standard console during the backup. Unless there is a real need to see the filenames as they are backed up we suggest not using the .v option.

•For commands that use density and tape size settings the tape density is 124,000 bpi and the tape length is 1800 feet.
