Move or mirror OneDrive and OneDrive for Business into Google Drive, Dropbox, Box, S3, R2 or B2 — scheduled, incremental, and safe to preview before it deletes anything.
No credit card. Free plan includes 2 GB of transfer every month.
OneDrive
Google Drive / S3
Works with personal accounts and OneDrive for Business.
The problems people bring us, and what we do about them.
“I'm leaving my job / changing tenant and need my files out.”
Connect the account while you still have access and copy the folders you own to a cloud that is yours. It runs server-side, so it keeps going after you log off.
“The OneDrive client keeps pausing and I never notice.”
Server-side schedules don't pause. If a run fails, you get an email rather than silence.
“I need Microsoft and Google to hold the same files.”
Two-way sync keeps both editable, or mirror one direction if one side should be the master copy.
“Company IT limits what I can install.”
There is nothing to install. Syncrix is a web app; the transfer happens between the two clouds.
Personal and Business accounts
Both OneDrive and OneDrive for Business connect as providers, so personal and work content can be handled with the same rules.
Scheduled incremental sync
After the first run only changed files move, which keeps daily syncs quick and your transfer quota low.
Dry-run preview before anything is deleted
Mirror mode can delete files at the destination, so every rule can be previewed first: exactly which files would be copied, updated or removed — before a single byte moves.
Nothing is stored on our servers
Files are streamed straight from the source cloud to the destination. Once a transfer finishes, no copy of your data remains with us — we keep only file names and sizes needed to resume the next run.
Audit trail of every change
Renames, moves, deletions and overwrites are recorded per job, so you can answer “what happened to that file?” months later.
Large files handled properly
Uploads are streamed and chunked rather than buffered whole, so multi-gigabyte files don't fail halfway.
Review the list, then run it for real. Mirror mode never deletes anything you haven't seen first.
Handing a tool access to years of files deserves scrutiny. Here is exactly what happens.
No copies kept
Files stream from source to destination. Nothing remains with us after a transfer — only names, sizes and timestamps so the next run can skip unchanged files.
Tokens encrypted at rest
Cloud credentials are encrypted with AES-256-GCM and never written to logs. Disconnect a cloud, or delete your account and its data, whenever you want.
Least access we can ask for
For Google Drive we use the drive.file scope — we can only touch what you pick or what we create. Your data is never used to train AI models.
Connect OneDrive (or OneDrive for Business) and your destination cloud.
Create a rule with the folders you care about and choose copy, mirror or two-way.
Preview the plan, then save it with a schedule.
Get notified on completion or failure — and check the per-file log any time.
Yes, it connects as its own provider type alongside personal OneDrive.
Yes. Folders are recreated at the destination and each transferred file is logged with its relative path.
Yes — pick two-way mode and a conflict strategy, then set a schedule.
Files are streamed through the transfer worker and never stored, and access tokens are encrypted with AES-256-GCM. We don't browse customer content.
