Manual method
Download selected Dropbox files and folders as independent local copies.
- Sign in on dropbox.com and select the files or folders to preserve.
- Choose Download and save the individual file or ZIP outside the Dropbox sync folder.
- Split large folders into smaller batches; the documented folder-download ceiling is under 250 GB and fewer than 10,000 files, including nested files.
- For collections that exceed browser limits, use the desktop app to make chosen files local, then copy them to an independent archive.
Coverage and limitations: A current-file download does not promise deleted files, all revisions or comments. Dropbox documents comments as a separate download operation. Online-only placeholders are not a backup.
Size and time to allow
Illustrative small / central / large case: 1 / 25 / 500 GB (decimal GB). These are planning assumptions, not a measured average per person. 25 GB is an illustrative documents and media collection; a creative-work account may occupy hundreds of GB.
Preparation: Expect small downloads promptly and allow minutes for large ZIP preparation as an estimate. Network and browser limits can force a restart.
For the central 25 GB example, network transfer alone is approximately:
| Connection | Estimated transfer |
|---|---|
| 10 Mbps | 7.9 hours |
| 50 Mbps | 1.6 hours |
| 100 Mbps | 47.6 minutes |
Assumes 70% sustained use of the stated connection. Provider throttling, many small files, retries, local extraction and copying add time. For online backup use your upload speed. These are not estimates of the provider’s preparation queue. See calculation and large-file advice.
Store and verify the archive
An encrypted external drive is a practical main archive; a USB key can carry a copy if it has sufficient free space. Keep an additional encrypted copy on another device or private online backup, outside the source account’s sync folder.
Create dropbox/YYYY-MM-DD/originals/, preserve the untouched download, and extract a separate working copy when needed. Allow extra free space for archive plus extraction; compressed text can expand far beyond twice its size. Record account/scope, export date, date coverage and missing items in a local README without passwords.
Extract ZIPs, inspect folder counts, open representative large files, and retain any separately downloaded comments. Reopen a sample from the second copy before deleting or replacing any source. Storage choices and verification.
