I am trying to find a tape rotation strategy that would be optimal under the following conditions:
Backup Media Rotation strategy should support the following:
- Media Archives required every 28 days retained up to 3 years
- Require to recover to any point in time within past 7 days
- Can sustain up to 1 week gap in recovery time for next 4 weeks
I believe a good strategy would be to use the Grandfather-father-son strategy. However, I am unsure about point 3 above. Can someone explain what point three entails?
