REPLACEMENT BACKUP WINDOWS 95 SW

I continue to have problems w/ the Backup sw included in Windows 95. My system crashes intermitently when requiring more than 1 disc/program or I get a “fatal error in List Manager” message when the back-up of a particular program is complete. I’m looking for any free sw that can replace the Windows back-up program. I back-up once a month & use about 7 discs.
Any advice is appreciated.
Thanks, Nick.
