How to quickly divide a file into smaller segments with 7zip on RedHat

I have a very large file ~ 1.7 TB that’s causing me some issues with its transfer over NFS.

I use 7z to split it into into multiple smaller files and then transfer them:

7za -v900g -mx0 a MY_BIG_FILE_SPLITTED.7z /MY_BIG_FILE

Where:

7za: is the 7zip executable

-v900g: the size of the splitted files, here it’s 900 GB, you can alternatively use g, m, k or b

-mx0: Zero compression ratio, in other words: copy mode

a: destination file

Note: To install 7zip on RedHat, just use “yum install p7zip”

Enjoy!
