Backup for Microsoft 365 / G Suite / Salesforce
Business users of the cloud platform provided by Microsoft 365, Google G Suite or Salesforce automatically expect their data to be backed up just because it is in the cloud. In some instances, they are correct and some of these services do provide a basic backup, but this will not cover your business against many of the common data loss causes. People delete or overwrite data.
This can be done either accidentally or intentionally. If you don't notice that the data is not there within a relatively short period of time, that data will be lost forever. Then there is the ever-present threat of ransomware, other malware and hacks, which can live in systems undetected for long periods of time all whilst causing issues to data and data access.
You can also be presented with situations where if the platform you are using has an outage for long periods of time and you're not able to access your data.
