Hot and cold

One drive travels, one stays home. MothaSync keeps the two in sync — your backup tool of choice picks the home drive up from there.

Drive A Travels with you used every day Drive B Stays at home kept as your backup

Reporting

Sync several PCs or set one up for someone else. You get a nudge as soon as drives go stale or a run fails.
