Question : HP-UNIX - compressing/zipping files that are 31GB

I have a HP-UNIX Server (B.11.11).

I need to tar a directory but there are 2 files that are 31GB in size. To tar files, all files shouldn't be above 8GB.

Normally I would gzip the files that are slightly above 8GB before tarring the files.

If I were to gzip the 31GB files, it surely will not reduce to below 8GB.

Is there any way I can zip, compress etc these 31GB files so that I can tar all the files in the directory?

when you do export, backup or dump will contain data and no space. On the other hand, if you do cold backup or OS backup then it will contain the empty space as well.
