You have been asking for the -r option:
case 'r':
doretension = 1;
break;
Why don't you simply look into the source code? ;-)
Compressed dump should be easy, since we are Unix:
dump 0uBf 150000 - / | gzip | dd conv=osync | ft 'my compressed dump'
Of course, you have to estimate the tape capacity (150 MB in the above
example).
Appending files seems to be unsupported. -- Don't ask me, i wouldn't
trust these devices, all of the above is what i know from either the
sources or the man page. (I wonder why _you_ don't use them? *smile*)

Never trust an operating system you don't have sources for. ;-)
