Most businesses don’t give much thought to where their files actually sit until someone forces the question. Usually it’s a client sending over a vendor security questionnaire, or an auditor who wants specifics on how contracts and financial records are stored. "Somewhere in the cloud" won’t cut it as an answer. You’ll need to point to real details, ones that hold up when someone pushes back on them. So before you hand your company files over to any provider, here’s what you should actually be checking.
How Much Storage You’ll Really Use
Free tiers always look generous at first. Then you start uploading scanned contracts, high-res project files, years of financial records, and suddenly that headline storage figure means nothing. The real question isn’t how much space you get on day one. It’s how fast you’ll burn through it and what the price jump looks like when you do.
Check whether the provider charges per user or per team, and find out if storage is pooled or locked to individual accounts. A plan offering each user 100GB sounds decent until you realise five team members can’t dip into each other’s allowance. Also look at upload limits for individual files, because large presentation decks and video recordings will hit those ceilings before you expect them to.
Version History and Recovery Windows
Overwriting a contract by accident or deleting the wrong folder happens far more often than anyone will admit. Without proper version history, that kind of mistake can spiral into something genuinely painful to fix.
Some providers keep previous versions for 30 days. Others stretch to 90, and a few will let you roll back indefinitely if you’re on a higher-tier plan. For businesses that deal with regulated documents, you’ll want a provider that logs who changed what, and exactly when they did it. That kind of audit trail isn’t just handy for internal accountability. It’ll also help you satisfy compliance requirements from bodies like the ICO if you’re handling personal data under UK GDPR.
Provider Access and Encryption Types
Encryption is where most people get tripped up. The difference between encryption types sounds technical, but it matters enormously in practice. Plenty of providers will encrypt files on their servers, which protects the data from outside attackers. But the provider can still read your files. If you’re storing contracts, financial records, or anything covered by a confidentiality agreement, that gap is a problem.
End-to-end encryption works differently. Files get encrypted on your device before they ever leave it. With cloud storage built on this model, the provider holds encrypted data it physically can’t decrypt, meaning even a breach at their end won’t expose your documents in readable form. When a client or auditor asks whether your storage provider can access their files, this is the only setup that lets you give a flat "no."
Who Can Access What, and How Easily
Sharing permissions are where things start to fall apart for most teams. One shared link with no expiry and no password sitting in someone’s inbox can put confidential client files a single forwarded email away from being completely public.
Before you commit to a provider, actually test the permission controls yourself. Can you set view-only access on a single file? Can you kill a shared link once the project wraps up? Can you block downloads while still letting someone preview a document? Every business storing client work should have access to these controls as a baseline, not as an add-on buried in an enterprise pricing tier.
The Decision Is Harder to Undo Than You Think
Choosing a cloud storage provider isn’t something you can casually revisit a few months down the line. Once your team’s files, folder structures and sharing links are all baked into one platform, moving everything somewhere else turns into a project nobody wants to manage. The contracts you’ve shared with clients, the permissions you’ve set up, the version histories you depend on for audits, all of that lives and dies with whichever provider you pick today.
Ask the harder questions now, especially about encryption and who can access your data, so you don’t find yourself scrambling when a client questionnaire exposes a gap you didn’t know was there. A bit of upfront research will spare you those awkward conversations later and give your clients real confidence that their data is properly protected.
