In most cases, the Backup Server uses a default tape density
and block size that are optimal for your operating system; Sybase
recommends that you use them.
You
can specify a density, block size, and capacity for each dump device. You
can also specify the density, blocksize,
and capacity options in the with clause
for all dump devices. Characteristics that are specified for an individual
tape device take precedence over those that you specify using the with clause.

size, and capacity
