Today I was transferring a large 7 GB backup file into another server. Every time I copy it gets disconnected after some time and I have to transfer again. When transferring large files, it is better to split it into smaller files, this way if one of the file transfers failed, you only need to transfer this specific file again. With rsync, it make it easy as you can sync all files to remote server.
To split a large file into smaller parts, run
split -b 500MB LARGE_FILE.tar.gz
This command will split a large file into smaller files with 500 MB size each. You can specify a different size if you need.
Once all files are on the new server, you can combine them into one file with the command
cat * > LARGE_FILE.tar.gz
When you do cat *, make sure only split files are in the current folder.
