ufsdump

The ufsdump command provides a number of capabilities including
incremental backup and restore operations. Foremost for the tape library, the l
parameter fills each tape and then loads the next tape using of the library
sequential mode. To access the on-line man page, type man ufsdump.
The ufsdump command replaced the dump command. The dump command
does not offer the l parameter and so it is not very useful for the tape library.
With the dump command, you must provide a complex set of parameters that
specify how much capacity is to be stored on each tape. This is very difficult to
use with the data compression capable drives because the compressibility, and
thus the data capacity, can not be determined with any degree of certainty. Use
the ufsdump command instead of the dump command.
