Cloud storage has become the default filing cabinet: documents, photos, designs and client deliverables all live online. Google Drive, Microsoft OneDrive and Dropbox are the best-known options, and any of them will do the basics. The right choice depends on the software you already use, how you share files and how much control your business needs.
Note: free storage amounts, plan prices and features change. Verify details on each provider's website before committing.
Key takeaways
- Google Drive: best with Google Workspace apps and for generous free space.
- OneDrive: best for Windows and Microsoft 365 users.
- Dropbox: strong, simple syncing and file sharing, popular with creative teams and freelancers.
- None is a backup by itself: keep a second copy of critical files.

Security and privacy checklist
- Use a long, unique password in a password manager: see our guide.
- Turn on two-step verification, preferably with a passkey or security key: 2FA guide.
- Review who has access to shared folders every few months, and remove old links.
- Do not store plain-text passwords or ID scans in shared folders; encrypt or protect sensitive files, for example PDFs with our protect PDF tool.
- Beware of phishing emails that imitate "file shared with you" notifications: see how to spot phishing.
- Use business plans with admin controls and audit logs for company data.
Backups: cloud sync is not enough
Sync services copy deletions and corruption to every device, and ransomware can encrypt synced files. Follow the 3-2-1 rule: three copies, on two kinds of storage, with one off-site or offline. Keep important archives on an external drive or in a separate backup service, and test restores. Our small business cybersecurity guide explains backup basics.
Tips for organising files
- Use a clear folder structure by year, client or project.
- Name files with dates and versions:
2026-10-proposal-v2.pdf. - Compress large images and videos before uploading to save space: see how to compress images.
- Merge many PDFs into one packet with our merge guide.
- Delete duplicates and empty the bin occasionally.
