What to do if…
a cloud drive app starts re-downloading everything and you fear data duplication or overwrite

Short answer

Pause syncing right now, then make a “safety copy” of the local cloud folder (with sync still paused) before you delete, rename, or move anything. Once things are frozen, check in the cloud website whether it’s only downloading—or also recording/uploads changes.

Do not do these things

  • Don’t start deleting “duplicates” while syncing is still running—you can delete the wrong copy.
  • Don’t bulk-move/rename whole folders during the re-download; that often creates conflicts and more duplicates.
  • Don’t keep editing shared/work documents until you’re sure the app isn’t uploading from the wrong place.
  • Don’t uninstall the app before you’ve paused sync and made a safety copy (reinstalling can come later, once you’ve preserved your options).
  • Don’t assume “re-downloading” means “overwriting”—some services create conflicted copies or keep versions, but you need to confirm.

What to do now

  1. Freeze changes on this device (stop sync activity).

    • In the desktop app, choose Pause syncing or Quit/Exit.
    • If it won’t stay paused (or keeps restarting), use the app’s settings to sign out / unlink / disconnect this device.
    • If you still can’t stop activity, temporarily disconnect Wi-Fi/Ethernet on the device to buy time.

  2. Make a quick safety copy (with sync still paused).

    • Copy the local cloud folder (or only the affected folders) to a separate location, clearly named like Cloud Safety Copy - 2026-03-09.
    • If space is tight, prioritise recently edited folders and anything irreplaceable.
    • If you suspect files were mid-download, don’t rely on those alone—plan to also grab a clean copy from the cloud website later.

  3. Check the cloud website for “what changed” and “what’s recoverable.”

    • Look at Activity/Recent to see whether there are unexpected changes.
    • Check Recycle bin/Trash for recently removed items you may need to restore.
    • Pick 2–3 important files and check Version history/Previous versions (to confirm you can roll back if needed).

  4. Work out the duplication pattern before you touch anything.

    • Look for names like “conflicted copy”, “(1)”, “copy of”, or “conflict”.
    • Open a couple of examples and compare content plus last modified time (not just file names).

  5. Reduce overwrite/conflict risk before resuming sync.

    • If available, switch temporarily to online-only / files-on-demand or use selective sync so you don’t pull everything while assessing.
    • Confirm you have enough free disk space and your device date/time is correct (sync clients can misbehave when storage is low or the clock is wrong).

  6. If this is work/school data, treat it like a potential data incident until proven otherwise.

    • Keep sync paused and report it through your organisation’s IT/helpdesk or security route (especially if personal data, shared drives, or client files are involved).
    • Ask them whether you should re-link the device or whether they want to check account/session activity first.

  7. If you suspect account compromise on a personal account, secure it before re-syncing.

    • Change the account password and turn on 2-step verification (2SV) for the cloud account and the email account connected to it.
    • Review signed-in devices/sessions and sign out anything you don’t recognise.

  8. Resume syncing in a controlled test.

    • Resume sync and watch the status for a few minutes.
    • If you see unexpected uploads/renames/deletions starting, pause immediately and move to official support (or your IT team).

What can wait

  • You do not need to deduplicate folders right now.
  • You do not need to decide whether to reinstall the app right now.
  • You do not need to reorganise your cloud structure right now.
  • You can delay any “which copy is correct?” clean-up until you’ve confirmed activity and recovery options.

Important reassurance

A sudden full re-download is often triggered by settings changes, reindexing, cache resets, selective-sync changes, or a client update—not automatically by data loss. By pausing sync and making a safety copy first, you’ve already avoided the most common irreversible mistakes.

Scope note

These are first steps to stop harm and preserve options. Provider-specific troubleshooting (or IT support) may be needed afterwards to prevent repeats.

Important note

This is general information, not professional advice. Cloud services and app versions differ. If anything suggests unexpected uploads or widespread changes, keep sync paused and use the provider’s official support (or your organisation’s IT/security process) before proceeding.
