I'm using Perl's Archive::Tar module. It preserves the file permissions but doesn't preserve the sticky bit. At the other end where I extract the archive, all the sticky bits are gone. I think UNIX/LINUX operating system stores these sticky bits somewhere...

I'm using Perl's Archive::Tar module. Problem with it is it pulls everything on to the memory and the does archiving and then writes on to the file system so there is limitation on the maximum file size that can be archived. Most of the times it says ...

It looks like Archive::Tar::Wrapper is your best bet.
It looks like there is a different module that doesn't use an in-memory structure: Archive::Tar, it is better than puppet-stringing tar yourself.

On the same platform as you're tarring on? They may be different versions of tar (e.g., GNU and old-unix would notice if the compression generated errors, yes?

I am using tar to archive a group of very large (multi-GB) bz2 files.
If I use tar -tf file.tar to list the files within the archive, this takes a very long time to complete (~10-15 minutes).
Likewise, cpio -t < file.cpio takes just as long to complete...

But, you refer to cp -i and tar c existing files; don’t overwrite....
