Migrate Box to Google Drive, OneDrive, Dropbox or S3

What is Box?

Box is the enterprise-first cloud content platform that anchors the document layer for over 100,000 organizations and 68 % of the Fortune 500, including Procter & Gamble, Schneider Electric, AstraZeneca, and the U.S. Department of Justice. Where Dropbox and Google Drive grew bottom-up from consumers, Box went top-down with deep IT controls — granular sharing permissions, watermarking, governance retention policies, content-aware DLP, and tight integrations with Salesforce, Microsoft 365, Slack, ServiceNow, Workday and the Box Sign e-signature workflow. Free Personal accounts get 10 GB storage with a strict 250 MB per-file upload cap; the $15/user Business plan unlocks unlimited storage; Enterprise ($35) raises the file size cap to 50 GB and Enterprise Advanced goes all the way to 500 GB per file.

What makes Box hard to migrate away from is the same thing that makes it valuable: deep metadata, custom workflows in Box Relay, granular collaboration permissions on every folder. CloudsLinker won't preserve every Box-only metadata field across providers — no third-party tool can — but it does give you a server-to-server path for the file content, folder hierarchy, and modification timestamps, so you can consolidate Box into Microsoft 365, Google Workspace or any S3-class object store without downloading terabytes through your laptop. CloudsLinker authenticates with Box's standard OAuth 2.0, so no API keys to manage and no risk of credential exposure on shared machines.

Key features of Box

10 GB free, 250 MB per-file cap

Box Personal Free is generous on storage but harsh on file size — single uploads are capped at 250 MB, the lowest of any major consumer cloud. Many Personal users outgrow this in their first week of video uploads.

Business $15: unlimited storage

The Business tier removes the storage cap and raises file size to 5 GB. Most teams that consolidate on Box land here; CloudsLinker works seamlessly with all paid plans.

Enterprise: 50 GB files

The $35/user Enterprise plan adds 50 GB max file size, advanced DLP, and Box KeySafe (BYOK encryption). Common in regulated industries — finance, healthcare, government.

Enterprise Advanced: 500 GB files

Raised from the 150 GB legacy ceiling — Box now supports files up to 500 GB on Enterprise Advanced. Useful for video / 3D / scientific datasets that previously had to live on S3.

1,000 API calls/min rate limit

Per-user throttling kicks in around 1,000 requests per minute. Aggressive rclone-style pulls hit this fast; CloudsLinker auto-throttles and resumes on <code>429</code> responses without manual intervention.

Box KeySafe & encryption

Enterprise customers can bring their own AWS KMS or Box-managed keys. CloudsLinker reads decrypted content via the API; encrypted-at-rest is preserved on the destination if it supports KMS.

Why connect Box to CloudsLinker

CloudsLinker connects to Box through Box's official OAuth 2.0 flow with the Files Read/Write scope. Once authorized, every transfer runs cloud-to-cloud over Box's REST API — no local download, no bandwidth used on your end. The connector handles Box's per-user 1,000 API calls/minute throttling automatically with exponential back-off, supports both folders and Box Notes, and works against all Box plans from Personal Free through Enterprise Advanced. Use as source for migrating off Box, as destination for backing up other clouds into Box, or for two-way sync between Box and Google Drive / OneDrive / Dropbox.

What you can do with Box on CloudsLinker

Direct Box-to-any-cloud copy

Move Box folders to Google Drive, OneDrive, SharePoint, Dropbox, S3, Wasabi or B2 without downloading. Files stream cloud-to-cloud over Box's API.

Runs on our servers, not yours

Box jobs execute on CloudsLinker infrastructure. Close the laptop — your migration finishes regardless of whether you stay online.

Scheduled & incremental sync

Hourly / daily / weekly schedules with delta-mode incremental sync. Useful for keeping a Box folder mirrored to a SharePoint library or an S3 backup bucket.

Filter by Box folder, file type, size

Migrate only <code>/Marketing/2026</code>, skip files > 5 GB, or back up just PDFs and Excel files. Stack rules to handle multi-TB jobs precisely.

Common Box transfer scenarios

Migrate Box → Microsoft 365 / SharePoint when consolidating on Microsoft

Many enterprises that started on Box later standardize on Microsoft 365 for the bundled Office + Teams + SharePoint stack. CloudsLinker copies Box folder trees directly into SharePoint Document Libraries or OneDrive for Business, preserving folder hierarchy and modification dates. Multi-TB tenant migrations that used to take Box Shuttle weeks finish in days, with audit logs per file.

Off-site 3-2-1 backup of Box to Wasabi or Backblaze B2

Box's native trash retains deleted files for only 30 days on Personal/Business. For real disaster recovery, schedule a nightly CloudsLinker incremental from Box to Wasabi ($6.99/TB, no egress) or B2 ($6/TB) with Object Lock enabled. A 2 TB Box account becomes ransomware-resistant for ~$14/month in destination storage.

Bidirectional sync Box ↔ Google Drive for hybrid teams

Companies running Microsoft 365 internally but collaborating with Google Workspace partners often need a shared folder visible from both sides. CloudsLinker's two-way sync keeps a Box folder identical to a Google Drive folder with conflict rules (newer wins / source wins / keep both).

Archive cold Box content to S3 Glacier Instant Retrieval

Paying $35/user × 100 seats ($42K/yr) for Enterprise Box when 80 % of the data hasn't been touched in 18 months is wasteful. Use a CloudsLinker filter (modified-before-date) to move cold projects to S3 Glacier Instant Retrieval at $0.004/GB — typically 90 % cheaper per TB than Box.

Tenant consolidation after M&A

When Company A acquires Company B and both run Box, the merger creates two parallel tenants with overlapping users. CloudsLinker scripts user-by-user migration with mapping tables, preserves folder structure, and logs every file copy for legal/compliance audit.

How to connect Box to CloudsLinker

Box uses OAuth 2.0 — no passwords or API keys leave your browser.

Connection steps

Open CloudsLinker and click Add Cloud → choose Box.
The browser redirects to Box’s official authorization page (app.box.com/api/oauth2/authorize). Verify the domain before entering credentials — never approve OAuth from a domain you don’t recognize.
Sign in with the Box account that owns the files. For Business / Enterprise tenants, your IT admin may need to whitelist the CloudsLinker app in Admin Console → Apps → Custom Apps Manager before you can authorize.
Review the requested scopes — CloudsLinker requests Read and Write all files and folders stored in Box. Click Grant access to Box.
You’re redirected back to CloudsLinker with the connection active. Box appears in your cloud list, ready to use as source or destination.

Box Enterprise note

If your Enterprise admin has enabled the Custom App approval workflow, your initial OAuth attempt will be rejected with “App not approved.” Send the CloudsLinker Client ID to your Box admin to whitelist; this is a one-time action per tenant.

Revoke access

To revoke CloudsLinker’s access later: https://app.box.com/account/notifications → Authentication Settings → Authorized Applications → find CloudsLinker → Disable. Or from Admin Console for Enterprise tenants.

Box upload & download limits you should know

Box’s limits vary dramatically by plan tier — file size in particular ranges from 250 MB (Free) to 500 GB (Enterprise Advanced). Plan accordingly before starting a multi-TB job:

Personal Free: 10 GB storage, 250 MB max single file — the most restrictive file-size cap of any major consumer cloud.
Personal Pro: 100 GB storage, 5 GB max single file (~$10/mo).
Starter / Business: 100 GB → unlimited storage, 5 GB max single file ($5–15/user/mo).
Enterprise: unlimited storage, 50 GB max single file ($35/user/mo).
Enterprise Advanced: unlimited storage, 500 GB max single file (raised from the legacy 150 GB ceiling in 2025).
API rate limit: approximately 1,000 calls per user per minute, with stricter limits on certain endpoints (e.g. uploads). CloudsLinker handles 429 Too Many Requests with exponential back-off.
Trash retention: 30 days on Personal/Business; configurable up to 90 days on Enterprise.
Version history: unlimited on Business+; 10 versions on Personal.
Bandwidth: no published cap on uploads or downloads for paid tiers; Free tier downloads are throttled if abused.

Box + CloudsLinker — Frequently Asked Questions

Does CloudsLinker store my Box files on its servers?

No. CloudsLinker streams bytes directly from Box to the destination cloud over TLS. Files are never written to disk on our infrastructure — only transfer metadata (file name, size, status) is logged for audit purposes.

What's the largest file I can transfer from Box?

Depends on your Box plan. Personal Free is capped at 250 MB per file; Starter / Business at 5 GB; Enterprise at 50 GB; and Enterprise Advanced at 500 GB (raised from 150 GB in 2025). CloudsLinker uses Box's chunked upload API to handle anything within these caps.

Will my migration hit Box's API rate limits?

Box throttles around 1,000 API requests per user per minute, with stricter limits on certain endpoints. CloudsLinker uses exponential back-off on 429 Too Many Requests responses and resumes automatically. Multi-TB migrations from Box typically complete at 200–500 GB/day per connection.

Does this work with the free Box Personal plan?

Yes. CloudsLinker works with Personal Free (10 GB / 250 MB-file), Personal Pro, Starter, Business, Business Plus, Enterprise, and Enterprise Advanced. The OAuth flow is identical across tiers — only the storage and file-size caps differ.

Can I migrate between two Box accounts or tenants?

Yes. Connect each Box account separately as its own cloud in CloudsLinker, then run an account-to-account copy. Folder structure, modification times and tags are preserved. Sharing permissions don't transfer between tenants — that's a Box constraint, not CloudsLinker's.

What happens to Box Notes and Box Sign documents during transfer?

Box Notes are exported as .pdf or .docx when the destination is a non-Box cloud (Box Notes don't exist outside Box). Box Sign envelopes can be exported as PDFs but the signing audit trail does not transfer.

Does CloudsLinker preserve Box folder permissions?

Within the same Box account, yes. Across providers, no — Box's collaborator permission model has no equivalent on Google Drive, OneDrive, or S3. CloudsLinker copies file content and folder hierarchy; you re-apply permissions on the destination using its native sharing model.

How long does 1 TB take to transfer out of Box?

Typical Box → Google Drive / OneDrive / S3 throughput is 200–500 GB per day per connection, mostly limited by Box's rate cap and per-file API call overhead. Many small files are slower than a few large files. CloudsLinker parallelizes within Box's quotas.

Is this an official Box partnership?

No. CloudsLinker is a third-party tool that uses Box's public REST API under your OAuth authorization. You can revoke access anytime from app.box.com → Account Settings → Apps → Authorized Apps.

Can I back up SharePoint or OneDrive into Box?

Yes. Box has unlimited-storage Business and Enterprise plans, making it a viable destination cloud. Schedule a nightly CloudsLinker incremental from SharePoint / OneDrive into a Box folder; folder hierarchy and modification dates are preserved.
