Why Secure Backup for SharePoint?
Microsoft has a number of recovery options for O365 data. However, if a user deletes a site or file - one of the most common causes of data loss - it is often the challenging to recover from with O365. If an administrator or end user in your organization simply deletes files and you cannot restore them, you would need to contact support and wait for a solution with no timeline guaranteed. If it is the data retention period has expired, your data could be gone for good.
The recommended approach is to have a solution that allows for individual item, file and container level backup and restores. This allows both end users and administrators the ability to work without worrying that their critical business data could disappear at any time without a chance of recovery.
