tar

I have a huge 500MB size tar file to upload. and It's took many hour estimate time.
I wish to split to files like mysqldump. The solution is split files with tar.

tar -cML 51200 -f files.tar large_file

-c, --create create a new archive
-L, --tape-length=NUMBER change tape after writing NUMBER x 1024 bytes
-M, --multi-volume create/list/extract multi-volume archive
