Transfer & Back Up Koofr to Any Cloud

What is Koofr?

Koofr is a Slovenian cloud storage service that has run since 2013 — it celebrated its tenth anniversary in 2023 by raising the free tier from 2 GB to 10 GB for life. All files sit in ISO 27001-certified data centres in Germany running on 100% hydropower, under EU jurisdiction and GDPR. Two things distinguish it from the big-name drives: there is no limit on individual file size (your OS or browser is the only constraint), and paid plans are unusually granular — from 25 GB at €0.5/month up to 20 TB, billed yearly with VAT included. Koofr's signature feature is 'one storage for all': you can link your Google Drive, Dropbox and OneDrive accounts into a single Koofr interface and browse them side by side. A free open-source companion, Koofr Vault, adds a client-side encrypted folder compatible with rclone's crypt format.

The catch sits in that signature feature: Koofr's built-in bridge to external clouds is capped by a daily transfer table — 1 GB per day on free accounts, 10 GB/day on the smallest paid plan, scaling with what you pay. Moving a 500 GB library through the free lane would take 500 days. CloudsLinker takes a different path entirely: it talks to Koofr's own storage over the Koofr API and copies data server-to-server between Koofr and 140+ clouds, so a bulk migration in or out finishes in one scheduled job instead of drip-feeding through a daily quota.

Key features of Koofr

Why connect Koofr to CloudsLinker

CloudsLinker connects to Koofr with your account email plus an app password — a per-tool password generated in Koofr's preferences, revocable on its own without touching your login. Once connected, CloudsLinker copies files directly between Koofr and Google Drive, OneDrive, Dropbox, Wasabi, S3 and more, preserving folder structure, with filters and scheduled incremental runs.

Common Koofr transfer scenarios

Escape the 1 GB/day external-transfer lane

Koofr's built-in Google Drive/Dropbox bridge is fine for browsing but throttled for migration — 1 GB/day free means a 500 GB move takes over a year. CloudsLinker copies the same library to OneDrive or Google Drive through the Koofr API in a single job, folder tree intact.

Repatriate data into the EU

Teams subject to GDPR or EU data-residency policies move working sets from Google Drive or Dropbox into Koofr's German, ISO 27001-certified data centres. CloudsLinker runs the migration server-to-server and a scheduled sync keeps the EU copy current during the cut-over.

3-2-1 backup: mirror Koofr to Wasabi

Koofr's free-tier trash keeps deletions only 7 days, and dormant accounts are purged after two years. A weekly incremental CloudsLinker sync into Wasabi (~$7/TB/month, no egress fees) adds the independent second copy that a 3-2-1 plan calls for.

Consolidate scattered clouds onto a lifetime deal

Koofr's lifetime plans (sold via StackSocial, e.g. 1 TB one-time) make it a popular final destination. CloudsLinker sweeps years of files from Dropbox, MEGA and old Google accounts into one Koofr tree — filters keep node_modules and installers out.

Exit Koofr in one clean pass

Switching providers? CloudsLinker copies your full Koofr library to S3, pCloud or OneDrive in one run instead of a folder-by-folder download marathon — worth doing before winding an account down, since the free tier's 7-day trash window leaves little room for mistakes.

How to connect Koofr to CloudsLinker

Koofr connects with your account email plus an app password — a dedicated password Koofr generates for third-party tools. Your regular login password will not work.

Before you start

• App passwords are shown once at creation — copy it before closing the dialog.
• Create one app password per tool (name it “CloudsLinker”) so you can revoke it later without disturbing anything else.
• App passwords are available on all plans, including the free 10 GB tier.

Connection steps

1. Log in to Koofr and open app.koofr.net/app/admin/preferences/password (Preferences → Password → App passwords).
2. Enter a name such as CloudsLinker, generate the app password, and copy it — it is displayed only this once.
3. In CloudsLinker, click Add Cloud → choose Koofr.
4. Enter a display name, your Koofr account email, and the app password, then confirm.
5. Koofr appears in your cloud list, ready as source or destination for transfers, sync and scheduled jobs.

To revoke access later: delete the app password on the same preferences page — revocation is immediate — then remove the Koofr connection in CloudsLinker.

Koofr limits you should know

Koofr’s storage numbers are generous; the ones to plan around are the trash window and the built-in transfer quota.

• Maximum single file size: none. Koofr publishes no per-file cap — only your OS or browser constrains uploads. The exception is Windows’ default 50 MB WebDAV limit, which CloudsLinker’s API-based connection bypasses.
• Free tier: 10 GB for life, raised from 2 GB in 2023.
• Paid plans: 25 GB at €0.5/month up to 20 TB, billed yearly, VAT included.
• Built-in external-cloud transfers are metered daily: 1 GB/day (free), 10 GB/day (Briefcase S), scaling to 20 TB/day (Crate 20XXL). This quota governs Koofr’s own Google Drive/Dropbox bridge — CloudsLinker’s API-direct route doesn’t pass through it.
• Trash retention: 7 days (free) / 30 days (paid), then permanent deletion.
• Inactive accounts are deleted after 2 years, per Koofr’s GDPR data-minimisation policy.
• Data centres: ISO 27001-certified, located in Germany, powered by 100% hydropower.
• Koofr Vault: optional open-source client-side encryption (XSalsa20-Poly1305), compatible with rclone’s crypt format.

Koofr + CloudsLinker — Frequently Asked Questions

Why does CloudsLinker need an app password instead of my Koofr password?

Koofr issues per-application passwords for third-party tools — your main login (and its 2FA) never leaves Koofr, and each tool's access can be revoked individually. Generate one under Preferences → Password → App passwords; your regular login password will not work in CloudsLinker.

What is the largest file I can transfer to or from Koofr?

Koofr sets no limit on individual file size — its help pages state the only constraints are your OS and browser. The one published exception, Windows' default 50 MB WebDAV cap, doesn't apply here because CloudsLinker uses the Koofr API, not WebDAV.

Does CloudsLinker work with a free 10 GB Koofr account?

Yes. App passwords are available on every tier, including the free Starter plan. The 10 GB storage quota is the practical ceiling — transfers that would overflow it fail on the Koofr side, so check the destination has room.

Koofr already connects to Google Drive and Dropbox — why use CloudsLinker?

Koofr's built-in connections browse external clouds but transfer through a daily quota: 1 GB/day free, 10 GB/day on the smallest paid plan. CloudsLinker moves data in bulk without that lane, reaches 140+ clouds rather than a handful, and adds scheduling, incremental sync and filters.

Can CloudsLinker transfer files inside my Koofr Vault folder?

Vault files are encrypted in your browser before upload, so any third-party tool — CloudsLinker included — sees only ciphertext. You can copy the encrypted blobs as-is (they stay decryptable with your Vault key or rclone's crypt remote), but for readable copies at the destination, move files out of Vault first.

How long do deleted files stay recoverable on Koofr?

7 days on free accounts, 30 days on paid plans — after that, Deleted files are purged permanently. If a transfer replaces or removes something by mistake, that window is your recovery budget.

What happens to an inactive Koofr account?

Koofr automatically deletes accounts inactive for more than two years, in line with GDPR. If you park an archive there, log in occasionally — or keep a CloudsLinker-synced second copy in Wasabi or S3.

Where is my Koofr data physically stored?

In ISO 27001-certified data centres in Germany, inside the EU, running on 100% renewable hydropower. Koofr the company is based in Ljubljana, Slovenia, and operates under GDPR.

How do I revoke CloudsLinker's access to Koofr?

Delete the app password at app.koofr.net → Preferences → Password — access ends immediately and your other app passwords keep working. Then remove the Koofr connection in CloudsLinker.

Is this an official Koofr partnership?

No. CloudsLinker connects through Koofr's public API using an app password you create and can revoke at any time.

Conclusion

Koofr pairs EU-hosted, no-file-size-limit storage with some of the most granular pricing in the market — but its built-in cross-cloud lane meters transfers by the day. CloudsLinker supplies the bulk path: one-pass migrations in or out and scheduled incremental mirrors to 140+ clouds. Generate an app password and run your first transfer in minutes.
