If you’re performing full image backups to NAS or RDX, you’ll want to seriously consider using a data container.
Normally, when you back up to an external device, Windows records your backup history on that device. Because of this, you can choose any day in the past you performed a backup, and then restore your data as it was on that particular day.
However, when you back up to a NAS or RDX drive, Windows can’t keep this backup history. You will only be able to restore your data from the last backup unless you create a data container.
