TimeMachine and reliable? I manage a TimeMachine (Mac)+Acronis (Win) deployment at work (storage: QNAP TS 1635) and it's a freaking mess.
Acronis: fast, reliable, tracking UI that shows status for admins, can be centrally deployed while allowing users to set their password individually, supports different backup schedules/retention periods and quotas
TimeMachine: dog slow (unusably so on Wifi), no central tracking, once a week a user has to fully wipe their backup because it somehow got corrupt, fully manual deployment necessary as there is no way to implement encrypted timemachine backups from a script, no way of individual quotas or restricting backup history...
