I was wondering if this has been tried or if I should try it on a test system? Say I make a full backup file and 10 incrementals. So I now have "Backup.tib" and "Backup2.tib" to "Backup12.tib". Say I restore my drive from "Backup6.tib" and then delete "Backup.tib" through "Backup6.tib". THEN I do a backup to "Backup.tib" again. Will "Backup7.tib" and the others still be valid? I know each file is a list of sector changes.. so in THEORY it should work since the new backup file is the state at which Backup6.tib would be at. But does it? Thanks!
