Split files with 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

Tar will asks you to change the volume with a question like.

Prepare volume #2 for "files.tar' and hit return: you just type "n filename" to give a new file name for the next (and subsequent) volume(s) like this. Prepare volume #2 for "files.tar' and hit return: n files_2.tar
Prepare volume #3 for "files_2.tar' and hit return: n files_3.tar
Prepare volume #4 for "files_3.tar' and hit return: n files_4.tar


** Do Not enter with no filename coz it will overwrite your file with last file name.
** volume #X must relate with file name (Prepare volume #4 you must enter n file_4.tar)

How to keep It back?

just use command below and enter your file name in the same way from compress process.

tar -xM -f files.tar Done!!
