Have you tried any?

"00001.server._home.1" is equivalent to one file on a tape.
You don't rewind one "tape file", you rewind the entire tape.
Your "tapes" are "file1", "file2", ...

However, each should have a directory named "data".
And the incremental dump file you show above should
have been created in that "data" directory.
