Dropbox backup & sync

Keep Dropbox mirrored somewhere else.

Copy or continuously sync Dropbox (personal and Business) to Google Drive, OneDrive, Box, S3, R2 or B2 — on a schedule, incrementally, with a preview before deletions.

No credit card. Free plan includes 2 GB of transfer every month.

Syncing 1,806 files…

Cheaper cold storage for the archive, Dropbox for the work in progress.

Sound familiar?

The problems people bring us, and what we do about them.

“I'm paying for Dropbox space just to hold an archive.”

Mirror the archive to object storage where a terabyte costs a few dollars a month, then trim Dropbox down to what you actively work on.

“A shared folder got wiped and the changes synced everywhere.”

A scheduled copy in a different provider gives you a version of yesterday that no collaborator can reach.

“Clients use Drive, my team uses Dropbox.”

Sync the shared folder between both and stop emailing zip files. Two-way mode keeps either side editable.

“I don't want another background app on my machine.”

There isn't one. Transfers happen cloud-to-cloud on our servers.

What you get

Dropbox and Dropbox Business

Both connect as providers, including team content, so business folders can be mirrored like any other source.

Incremental and mirror modes

Copy new files only, or make the destination match the source exactly — including removing what was deleted at the source.

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.

Pattern filters

Exclude caches, build folders or file types you don't want mirrored, so quota goes to files that matter.

Failure alerts you can route

Email plus optional Discord, Telegram or generic webhooks — put backup failures where you'll actually see them.

Review the list, then run it for real. Mirror mode never deletes anything you haven't seen first.

Data safety

Your data passes through. It doesn't stay.

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.

Four steps, about five minutes

  1. 1

    Connect Dropbox and your destination cloud.

  2. 2

    Choose the folders and the sync mode that fits — copy, mirror or two-way.

  3. 3

    Preview, then schedule it hourly, daily or weekly.

  4. 4

    Check the dashboard (or your webhook) for each run's result.

Questions people ask first

Can I sync only one Dropbox folder?

Yes. Rules are per folder pair, and include/exclude patterns narrow it further.

Does the sync run without my computer?

Yes, entirely on our servers on the schedule you set.

What if the same file changes on both sides?

In two-way mode you choose the conflict strategy: newest wins, keep both copies, or hold it for you to decide.

Is there a free way to test it?

Yes — 2 GB of transfer a month, two clouds and one rule, with no card required.
