Storage comparisons should focus on what happens when two devices change the same file. Use the cloud-storage alternatives page to shortlist options, then run a controlled test.
- Upload a mix of small, large, and Unicode-named files from two devices.
- Edit one file offline on both devices and inspect conflict handling.
- Delete and restore a folder; verify version history and retention period.
- Test sharing permissions, link revocation, encryption boundaries, and export.
- Measure transfer speed and total cost including egress or extra users.
Keep an independent backup. Sync faithfully propagates mistakes and deletions; it is not a substitute for recovery.
