I use smb-handler to a NAS to run my backups. It's not always stable, but it works. I've also used a USB stick and when I moved my system from the 18GB SCSI drive to the 120GB SSD I used the SSD on USB as the copy destination.
That is one thing that bothers me, though, is the absolutely and total silence of the system, now. The only reassuring sound is the floppy drive seek. Mind you, the 1200 has had its DoM for many years now so I did have a little forewarning.
