Can I delete photos from my phone after NAS backup?

Only after you understand the sync behavior and have another independent backup. A copied file is safer than a sync you have not tested.

Can I run on-NAS AI search (face / object / scene) on the same box?

Yes, if the NAS has the right hardware for it — Immich and PhotoPrism both run face / object / scene search locally without sending photos to a cloud.

NAS

NAS photos backup plan

Photos are usually the most irreplaceable home data. A NAS can organize and protect a local copy, but it still needs offsite backup.

Best for: Families and creators collecting phone, camera, and shared photo libraries.

Choose the source of truth

Decide whether phones, cloud libraries, or the NAS are the main organized copy.
Avoid two-way sync until you understand delete behavior.
Keep imports organized by person, device, year, or event.

Protect against accidental deletes

Use snapshots, recycle bins, versioning, or backup history if available.
Keep at least one backup away from the NAS.
Test restoring a small album before trusting automation.

Make family access simple

Use named accounts instead of one shared admin login.
Give viewers read-only access when possible.
Avoid exposing photo apps publicly until account security is solid.

Operator snapshotEvidence first

First proof

List where photos live today: phones, cloud library, computer folders, external drives, and existing NAS folders.

Screen to open

Phone photo app/cloud account/computer folders/external drives > library size and sync settings

Expected signal

Every current source is visible before imports start.

Stop boundary

Stop before deleting cloud, phone, or external-drive originals.

Layer path

1A NAS photo plan must separate source of truth, import method, sync/delete behavior, snapshots/versioning, offsite backup, user access, and restore proof.

2A NAS copy is useful, but photos remain at risk if it is the only local copy or if deletes sync everywhere.

3Deleting phone/cloud originals before restore and offsite proof is a stop point.

Runbook

Step-by-step runbook

Start here. Do each check in order, compare it to the expected result, and stop when the evidence explains the failure or the safe stop point applies.

Inventory all photo sources

Check: List devices, cloud accounts, folders, sizes, owners, and current sync behavior.

Expected result: No source of irreplaceable photos is hidden.

If not: If a source is unclear, do not start bulk cleanup.

Choose copy versus sync

Check: Decide whether NAS imports copies or participates in two-way sync.

Expected result: Delete behavior is understood.

If not: If not, use one copied test album only.

Protect the destination

Check: Enable snapshots, recycle bin, versioning, or backup history for the NAS photo share.

Expected result: Accidental deletes have a recovery path.

If not: If not supported, add backup before import.

Import a test album

Check: Copy a small album from one source, then open and restore it from a temporary path.

Expected result: The workflow preserves files and restores cleanly.

If not: If metadata or restore fails, adjust before bulk import.

Add offsite backup before cleanup

Check: Run and verify offsite backup of the photo library before deleting originals.

Expected result: Photos have NAS and independent offsite protection.

If not: If offsite proof is missing, keep originals untouched.

Safe stop: Stop before deleting cloud, phone, or external-drive originals.

Decision tree

If: Phones/cloud are still the source of truth.

Then: NAS should receive a protected copy, not destructive sync.

Action: Use copy/import workflows and verify delete behavior.

If: NAS is becoming the organized source.

Then: Backup and offsite copy become mandatory first.

Action: Enable snapshots/versioning and offsite backup before cleanup.

If: Two-way sync is desired.

Then: Delete propagation risk is high.

Action: Test with a small album and document delete behavior.

If: Family members need access.

Then: User permissions and read-only roles matter.

Action: Use named accounts and least privilege.

If: You plan to delete cloud or phone originals.

Then: Risk is too high without independent restore proof.

Action: Stop until NAS copy and offsite backup both restore.

Safe stop: Stop before deleting originals after first import.

Evidence

Evidence table

Symptom	Evidence to collect	Likely layer	Next action
Multiple photo sources.	Inventory of devices, accounts, folders, and cloud libraries.	Source mapping	Pick source of truth before import.
Concern about accidental deletes.	Snapshot/recycle/versioning settings and delete test.	Retention	Enable recovery window before sync.
Need family viewing.	User/group permissions and shared album settings.	Access control	Use named read-only users where possible.
Cloud originals may be removed.	NAS restore test and independent offsite backup.	Recovery proof	Do not delete until both are proven.

Reference

Commands and settings paths

Photo source inventory

Phone photo app/cloud account/computer folders/external drives > library size and sync settings

Where: On each device or account that holds photos.

Expected: Sources, sizes, owners, and delete behavior are documented.

Failure means: Unknown sources can be skipped or overwritten.

Safe next step: Inventory before importing.

NAS protection settings

NAS admin UI > snapshots/recycle bin/versioning/photo app retention

Where: In the NAS photo/share settings.

Expected: A recovery window exists before bulk import or sync.

Failure means: No retention makes delete mistakes harder to reverse.

Safe next step: Enable supported protection before automation.

Restore test

NAS backup/photo app > restore/export one album to temporary folder

Where: After importing a test album.

Expected: The album restores and opens outside the app.

Failure means: If restore is unclear, the plan is not ready for originals cleanup.

Safe next step: Fix backup/restore before expanding.

Offsite copy

NAS backup app/cloud backup target > latest job and restore status

Where: In the offsite backup tool.

Expected: A recent offsite copy exists for the photo library.

Failure means: Local NAS-only storage is still vulnerable to home-level loss.

Safe next step: Add offsite backup before deleting phone/cloud originals.

Hardware boundary

Hardware and platform boundary

Change only when

Expand NAS storage or photo apps only after source inventory, copy/sync behavior, snapshots, offsite backup, and restore proof are clear.

Evidence that matters

Photo app exportability, user permissions, snapshots/versioning, offsite backup support, and capacity growth matter.

Evidence that does not matter

AI tagging or gallery polish does not protect photos without restore and offsite evidence.

Avoid

Avoid two-way sync and deleting originals until restore behavior is proven.
