备份策略考虑

1. An appropriate recovery point objective (RPO) or the ability to roll back to a period of time from today

2. An appropriate retention policy, or the number of copies of previous periods of times retained

3. An appropriate recovery time objective (RTO) or the ability to restore the appro-priate backups in a set time

4. An appropriate location of both onsite and offsite backups to enable recovery of data in the event of a complete disaster, while still allowing for a quick restore onsite where needed

5. The ability to properly verify the validity of your backup infrastructure through regular testing and verification
