How do i add backups and restore points onto another HDD drive

I noticed that having my server run on a 256 drive along with backups is not going to work. I have a few HDD drives around. If i pop one in how do i make the saves go onto it instead of the main one. I am a noob links and videos would help a bunch. Thanks.

I’m at work but you’ll want to create a symbolic link from the servers backups (or any other directory) to the USB drive directory.
You can search the information yourself for creating symbolic links and can also find the location of the backup folder, though if it’s a mod creating the backup that backup folder might be different.

@ElPres gave the answer, I just provide som links:

Alright thanks a bunch I love learning Linux and these forums are a bunch of help.
