how do I back up and restore famicom disks?

[aclbandit]

I'm trying to find out how to back up and re-write my famicom disks, preferably somehow with my PC as the recipient of the backups as well as the restore-er.

I just wanna make sure that I don't lose my disks.

I've heard of FDSLoadr, but from what I can gather, it doesn't do what I need it to.

Anyone have any info about how to do this, or, indeed, at least what product(s?) I should be on the lookout for?

EDIT: Just as an FYI, I have attempted to Google this, and either info is scarce, or I suck at Google.
