SSD SM 1024L MEDIA FULL

connect a properly formatted hard drive (pretty much any one will do, as long as it's the same rough capacity as the SSD, which is no big problem)-should be formatted as MacOS Journaled, GUID On, via USB, Turn on Time machine, point it to the formatted hard drive you did, and tell it you want to use that drive as a Time Machine backup, and then.....do a backup...... after it's done, then maybe you can choose which stuff to get rid of. If you have ongoing storage problems, eg you keep running out of space on your startup disk, which I'm assuming is the SSD SM 1024L, then maybe you should look into getting a bigger one installed. Not gonna be cheap though, but it should solve your problem for now
