[Bug-tar] How can I restore incremental dump file?

[Jae Sang Lee]

Hi, 

I read this manual http://www.gnu.org/software/tar/manual/html_node/Incremental-Dumps.html#SEC94

I succeeded create incremental dump file.

$ tar --create -z --file test.1.tar.gz --g test.snar test

$ tar --create -z --file test.2.tar.gz --g test.snar test

But, How can I restore entire file? Is there only way that extract two file each?

for example)
$ tar --extract -z --file test.1.tar.gz
$ tar --extract -z --file test.2.tar.gz

I wanna extract increment dump file just one command using snapshot file.

like this.

$ tar --extract -z --file test.2.tar.gz --some-options..

I hope your answer, THX

Good luck.
