We had an email correspondence about this a while back and, having only recently setup backup on my new PC (big, brave gap...) I've just filled my first CD and now I've got two called DAILY301

I think I can see what's happening.
1 Start backup from shortcut on desktop created by AISBackup (1.7).
2 Loads backup and calcs required space.
3 Decides that there's not enough room for everything so it ejects the CD and demands a blank one.
4 To which it then writes the files that would fit on the original CD - and names it as the original CD.
5 After which it prompts for a blank CD again.
6 And writes the remainder of the files
This is a nuisance - although at least as I'm only 1 CD in it won't be too much of a pain to nuke the whole lot and start again.
