**
**		allocates an 16K bytes I/O buffer
**		intilializes header record common fields
**		do forever
**			walk through the backup file chain
**			intilializes header record unique fields
**			open backup file
**			writes out header record to backup file
**			points to the next backup file in the chain
**			calculates the actual file size ( minus header record length )
**			if the actual file size less than 16K bytes
**				set I/O size to actual file size
**			otherwise
**				set I/O size to 16K byte long
**			when it is the last backup file
**				reads data from standard input as much as indicated by I/O size
**					and writes it out to the last backup file until no EOF.
**				issues error message when disk space full condition is detected
**			otherwise reads and writes to backup files util EOF
**				if disk full cobdition is detected
**					flush the remaining data in the I/O buffer to subsequence
**							backup files
**				go back to normal read and write process util EOF
