Backup data strategy

Backup data strategy is a strategy, applied to the backup data process, regulating various parameters, like how much data is backed up at a time, how often backup is performed and which media is used. A backup data strategy usually aims at achieving both effectiveness and efficiency at the same time, in other words combining the best security with the least efforts and costs.
