The first time you perform a full backup of your server or end-point, our software takes a full
snapshot of your data and stores it for future reference.
The next time you perform a backup, it compares that snapshot against the data on your
machine, and only backs up what has changed. This minimizes the time, space and
processing power needed for your future backups.
When you only backup data that has changed since your last full backup, this is a
differential backup. An incremental backup does almost exactly the same thing, but from
your most recent backup, whether it's a full image backup or not.
