A factory reset is supposed to be a clean start. The problem is how thorough it is: it does not tidy the device, it empties it. Every photo, document, and download that lived only on that phone or laptop is gone the moment it completes, and no amount of signing back in brings them back. So the real question is not how to undo it. It is how to restore files after a factory reset from the copy you made beforehand, and how to do that without fumbling the one step people reliably get wrong.
That step is choosing between two operations with confusingly similar names: Restore and Restore Sync. Here is the difference, and the order to do things in.
First, the uncomfortable part
If you are reading this before the reset, you are in the good case. Skip to the checklist below, run your backup, then wipe.
If you are reading this after the reset, the honest answer is that you can recover exactly what was already copied somewhere else, and nothing that was not. A factory reset is not a recycle bin. There is no local undo. What determines your outcome was decided before the wipe, which is why the rest of this post spends as much time on the twenty minutes beforehand as on the recovery itself.
Worth saying plainly: Sync does not back up on a schedule or in the background. Tasks are set up once and run when you run them. A task you created in June and last ran in June contains June's files. Before a reset, the habit is: open the app, run the task, watch it finish, then wipe.
The naming trap: "Sync" means incremental, not two-way
Sync by Miciniti gives you five explicit operations rather than one vague sync button. Four of them come in pairs, and the pairing is where people go wrong:
| Operation | Direction | Deletes? |
|---|---|---|
| Backup | Device → drive | Never |
| Backup Sync | Device → drive | Never |
| Restore | Drive → device | Never |
| Restore Sync | Drive → device | Never |
| Full Sync | Both ways | Yes, mirrored both ways |
Read the table twice and one thing stands out: the word Sync in "Restore Sync" does not mean two-way. It means incremental — only the files that changed since the last run. Restore Sync moves files in exactly one direction, drive to device, the same as Restore. The only genuinely two-way operation in the app is Full Sync, and it is also the only one that ever deletes anything.
This matters after a reset because the instinct is to pick the option that sounds cleverer. Both are safe here — neither removes anything from your device — but only one of them is built for an empty device.
Restore: rebuilding from empty
Restore is a full one-way copy from a drive back to your device. It does not ask what you already have; it brings the set down. That is exactly the behaviour you want when the device has just been wiped, because there is nothing local to compare against and nothing to skip.
Reach for Restore when: the device is freshly reset, you are setting up a new phone or laptop, or you have lost a folder entirely and are rebuilding it from scratch.
Restore Sync: topping up a device that already has most of it
Restore Sync is the incremental version. When your device already holds most of the files and you only want what is newer on the drive, it brings back just those changes instead of re-fetching everything. On a large folder over a slow connection, that difference is minutes instead of an evening.
Reach for Restore Sync when: you already have the folder and you are pulling down the latest edits — the routine top-up, not the rebuild.
The choosing question is one line: does this device already have most of these files? No means Restore. Yes means Restore Sync. After a factory reset the answer is always no.
The full sequence, in order
Before the reset
- Open Sync and check which folders your backup tasks actually cover. The gap is usually a folder you added months after you set the task up.
- Run each backup task and wait for it to complete. Not "it ran recently" — run it now, watch it finish. This is the step that decides everything.
- Spot-check the destination. Open the drive and confirm the files are genuinely there, with sensible sizes. Trusting a green checkmark you did not look at is how people discover an empty backup at the worst possible moment.
- Consider a second copy somewhere independent — another cloud service, or a USB or external drive. Two copies in two unrelated places is most of what the 3-2-1 backup rule buys you, and a reset is precisely the kind of self-inflicted event where the second copy earns its cost.
- Now wipe the device.
After the reset
- Install Sync again and connect the same drive you backed up to.
- Create a task with the drive as the source and a folder on your device as the destination, using the Restore operation.
- Run it. Files come back down in one pass.
- Once the device is populated again, set up your Backup task afresh so the next copy is not another year away. The reset wiped the app's tasks along with everything else.
What this does not do
Being straight about the edges is more useful than a feature list:
- It does not recover files that were never backed up. If it was only ever on the device, the reset took it. There is no version of this post that changes that.
- It does not restore apps, settings, or system state. Sync moves your files. Your operating system's own device backup handles the rest, and the two are worth running together rather than instead of each other.
- It does not run on its own. No background service, no schedule. That is a deliberate trade — nothing leaves your device without you starting it — but it does mean the protection is only as fresh as your last run.
- It does not work on network drives or NAS. Sync does not support NAS or network drives. Cloud services, local storage, and USB or external drives are the destinations.
Restoring onto a different device
The same mechanics cover a swap rather than a wipe. Because the copy lives on a drive rather than on the old handset, a Restore task on a new device pulls the same files down — which is the whole basis of moving to a new phone without losing anything. Reset and replacement are the same job with different hardware at the end of it.
If the pairs still feel slippery, the full breakdown of all five operations and when each one applies is in 5 Sync Modes Explained. And if you are unsure whether what you have is a backup at all or just a mirror that will happily repeat your mistakes, Backup vs Sync is the one to read before the next reset, not after it.
Get Sync
Sync is free to start: connect any one drive at no cost, ad-supported, and set up your first Backup task in a few minutes. Additional drives and features unlock with a Sync subscription or a one-time lifetime purchase, whichever you prefer. Available on iPhone and iPad, Android, Mac, and Windows.
The best time to test a restore is a quiet afternoon when nothing has gone wrong. Run one now, on a folder you do not care about, so that the day you actually need it you are repeating something familiar instead of learning it under pressure.
Frequently asked questions
How do I restore files after a factory reset?
Set up the app again on the wiped device, connect the same drive you backed up to, and create a task that uses the Restore operation with that drive as the source and a folder on your device as the destination. Run it, and the files come back down. The one requirement is the part that happened before the reset: the copy has to already be on the drive, because a reset removes everything local and there is nothing to recover from the device itself.
What is the difference between Restore and Restore Sync?
Both copy one way, from a drive back to your device, and neither one deletes anything on your device. Restore pulls the full set of files, which is what you want when the device is empty or you are rebuilding a folder from scratch. Restore Sync brings back only the files that changed on the drive since last time, which is much faster when the device already has most of them. After a factory reset the device has nothing, so Restore is the one to reach for.
Does the word Sync in Restore Sync mean it works two ways?
No, and this is the most common misreading of the name. In Sync by Miciniti, the word Sync in an operation name means incremental, only what changed since the last run. It does not mean two way. Restore Sync copies in one direction only, from the drive to your device. Full Sync is the only operation that works in both directions, and the only one that ever deletes anything.
Will restoring delete anything already on my device?
No. Restore and Restore Sync only add and update files on your device, they never remove them. That is true of Backup and Backup Sync in the other direction too. Full Sync is the single operation in the app that mirrors deletions, and it is the one to keep away from anything you would call a backup.
Do I need to do anything before a factory reset?
Yes, and it is the whole ball game. Run your backup task and wait for it to finish before you wipe the device. Sync does not back up on a schedule or in the background, so a task that exists but has not been run since last month has last month's files in it. Open the app, run the task, confirm it completed, then reset.
I already reset the device without backing up. What can I get back?
Whatever was already copied somewhere else before the wipe, and nothing that was not. If you had run a backup task to a drive at any point, everything up to that run is sitting on the drive and a Restore brings it down. Files created or edited after that last run were only ever on the device, and a factory reset removes them. This is the honest answer, and it is the reason the run-it-first habit matters more than any feature.
