Data that is recovered frequently should be backed up to both on-premise storage and to cloud storage. This is because the on-premise backup assures faster recovery, while the off-premise copy can be used for disaster recovery purposes.

If the purpose of putting data in the cloud is for public accessibility, then backup the data locally even before storing in cloud.

If one can afford it, it is recommended to backup very important and critical data to multiple vendors to mitigate risks. This gives an extra level of safety in case one of the vendors has an outage at a business-crucial time.
