Azure备份保留策略

Question

我正在努力围绕Azure备份保留点，并想知道我选择的保留策略是否最佳。关于Azure定价计算器，如果我采用30个每日RP（恢复点）和5个每年的RP，将无法充分覆盖我的VM数据。

如果我忽略每周和每月RP，会错过什么？什么情况下需要每周和每月的RP？

Answer 1

If churn happens at a consistent rate daily, then having only daily is also fine If you see some unexpected churn take an adhoc backup and then give higher retention for that, If you observe that churn is possible mostly during month ends (say for finance applications), then having a monthly point might make sense
