Sync OneDrive to AWS S3 — Enterprise Cloud-to-Cloud Backup with RcloneView
Microsoft 365 doesn't include true backup. Deleted files, ransomware, or admin errors can permanently destroy OneDrive data. S3 backup provides the independent copy you need.
Microsoft 365's retention policies are not backups. Deleted items go to the recycle bin for 93 days, then they're gone. Ransomware can encrypt files that sync across all devices. Admin errors can wipe entire team sites. An independent backup on AWS S3 — outside the Microsoft ecosystem — provides genuine data protection.
