I don't think so, because the Linux kernel doesn't support multi-session and restore reads the raw device.
What? Linux has supported multisession since 2.3.4! Now as to what restore does, can't say. I want my backups in iso9660 format in most cases, so I use mkshadow to create a backup tree and save that as a session. However, you can just put the backup in a file and write that as a new session, create a standard new session iso image with mkisofs (and maybe use graft-points to do a rename if you like) then burn that.
The 100MB ZIP is pretty small for backups, CDs have more breathing room.
But in your case why don't you use rewritable CDs which should work
out of the box.
A second possibility is to directly write to the raw device of ZIP
drive. I'll try that and report later. But a ZIP medium is much more
expensive than a rewritable CD and you don't need a ZIP-drive either.
