ZimaOS can currently mount OneDrive in Files and can use cloud storage in Backup workflows, but those features should not be described as a native always-on two-way OneDrive mirror. The October 2025 user wanted a local NAS folder that continuously stayed synchronized in both directions with a personal OneDrive account.
Current official documentation still makes an important distinction between mounted cloud access, backup, and sync. That means the original search intent remains relevant even though ZimaOS cloud integration has improved.
What Current ZimaOS Can Do With OneDrive
The current cloud drive guide documents direct OneDrive mounting in Files, multiple accounts, cloud-to-local migration, and local-to-cloud copy workflows.
The current 3-2-1 Backup guide also supports cloud as a Backup source or destination.
Why Backup Is Not the Same as Two-Way Sync
ZimaOS’s own current Backup documentation explicitly says “Cloud Sync Is Not Backup.” A backup keeps restore points and writes forward; two-way sync mirrors changes and deletion in both directions.
If your goal is “this OneDrive folder and this local NAS folder should continuously converge,” do not assume a scheduled backup task provides that behavior.
Use rclone Bisync Only If You Accept Its Complexity
For an actual two-way folder synchronization workflow, a containerized rclone setup is one advanced option. The upstream rclone Bisync documentation documents its requirements and warnings.
Two-way sync is inherently more dangerous than one-way backup because a mistaken deletion or conflict can propagate. Test with expendable files first and keep an independent backup outside the sync pair.
Choose the Workflow by Goal
If you only need to browse personal OneDrive from ZimaOS, use the native Files mount. If you need a recoverable local copy, use the Backup app. If you need continuous bidirectional convergence, use a dedicated sync engine and accept its conflict/deletion rules.
The cloud integration overview shows the broader local/cloud model, while the cloud backup overview covers the backup path.
Bottom Line
The old statement “OneDrive is only a mount” is now incomplete because current ZimaOS also supports richer migration and Backup workflows. But a native continuously synchronized two-way OneDrive mirror is still a different feature. Pick mount, backup or dedicated sync based on the behavior you actually need.
