Which retention policy is applied if you desire an RPO of 1 minute and want to retain the snapshots for 5 days?

1. One daily snapshot is created and retained for 5 days.

2. For every hour, a snapshot is created and retained for 6 hours.

3. For every 1 minute, a snapshot is created and retained for the maximum of 15 minutes.

4. For every hour, a snapshot is created and retained for 12 hours.

The correct answer is: One daily snapshot is created and retained for 5 days.

To achieve an RPO (Recovery Point Objective) of 1 minute while retaining snapshots for 5 days, the retention policy must ensure that snapshots are taken frequently enough to meet the RPO and that they can be kept for the desired duration. The correct answer indicates that one daily snapshot is created and retained for 5 days. However, this policy does not actually meet the requirement for an RPO of 1 minute because taking only one snapshot per day would leave a significant period during which data could be lost. The other options available consider different intervals for taking snapshots. For example, one option suggests taking a snapshot every hour; however, this will also not meet the 1-minute requirement for RPO. Additionally, creating snapshots every minute and retaining them for a short duration risks losing data continuously. To meet the RPO of 1 minute while retaining snapshots for 5 days, a more appropriate policy would be to take snapshots every minute and ensure they are retained accordingly. Therefore, a proper policy description that fulfills the RPO of 1 minute along with a 5-day retention would typically align more closely with frequent snapshots. The overall context of this question focuses on understanding RPO and retention policies, with the correct strategy being to take regular
