Incremental backups form a chain that goes back to the original in which each subsequent backup only has the changes since the last backup.</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">To do what you're asking about you need a product that does differential backups.
