Can a Photos library live on a NAS or network drive?

By Kayabyte · Last updated 11 November 2026

Short answer: Apple says not to. Its page on moving a Photos library tells you not to store it on a device shared over your network or the internet, and asks for a drive formatted APFS or Mac OS Extended (Journaled) that is connected directly. If your library is already on a NAS, copy it to a local Mac-formatted drive, keep the original untouched, and open the copy with Option held down. We have not tested AlbumRescue reading a library straight from a network share, so we suggest scanning the local copy.

This guide is based on Apple’s page on moving your Photos library, checked 11 November 2026. Apple’s page doesn’t name NAS boxes; it only says “a device shared over your network”. A NAS is such a device, so we read it that way.

What Apple says

That last point is why a library on a NAS can look empty or “gone”. If the NAS sleeps, the share isn’t mounted yet, or the network drops, Photos can start a fresh empty library. Your photos are not deleted. They are still on the NAS.

If your library is on a NAS now

  1. Quit Photos. Don’t open the library again until you have a copy.
  2. Mount the share in Finder and make sure it stays awake. A sleeping NAS can make a copy stall.
  3. Copy the library to a local drive. Use a drive that meets Apple’s requirements: APFS or Mac OS Extended (Journaled), not used for Time Machine. In Finder, the library looks like one file called Photos Library, but it is a package, so a big one can take hours.
  4. Check the copy with File, Get Info on both: the sizes should be close. If the copy stops with errors, don’t start over on top of it; note which files failed.
  5. Turn on Ignore ownership on the new drive in Get Info, under Sharing & Permissions, as Apple’s page describes.
  6. Open the copy, not the original. Quit Photos, hold Option while opening it, click Other Library and choose the copy.

Opening a library in Photos can change it. That is the reason to keep the NAS copy as it is and work on the second one.

Time Machine on a NAS

Time Machine backups on a network drive are a different case, and Apple’s page about storing a library doesn’t cover them. AlbumRescue’s own help page says that for a Time Machine backup on a network drive you should open the backup in Finder first, so that the app can find it. See restoring a Photos library from Time Machine for what a backup does and does not hold.

Where AlbumRescue adds something

If Photos opens your copy and shows everything, you don’t need us. AlbumRescue helps when Photos won’t open the copy, when you don’t want Photos to touch it, or when you want folders of original files that follow your albums. It only reads, and it never opens or changes the library. It reads APFS, encrypted APFS once unlocked, HFS+ and exFAT volumes, read-only volumes and volumes with ownership ignored. Our tests did not include a library on a network share.

What it can’t do: it can’t fix a library, put albums back into Photos, or get originals that stayed in iCloud under Optimize Mac Storage.

Steps with AlbumRescue

  1. Copy the library from the NAS to a local drive, as above.
  2. Open AlbumRescue and connect the drive. Without Full Disk Access you can still choose a library on an external drive: click Choose a Library. A folder copied from a library works too.
  3. Click Scan. Read Overview and Before you pay, which say how many originals are really in the copy.
  4. Choose Export for a free sample of 5 photos in folders named after your albums, with sidecar files. Check them before you pay anything.

The scan, lists, comparison and 5 saved photos are free. The full export is USD 34 once, for 2 Macs. macOS 15 or later.

Questions

Can I keep my Photos library on a NAS? Apple says not to store it on a device shared over your network. Keep the working library on a drive connected to your Mac and use the NAS for backups of your own.

Why does Photos show an empty library when the NAS is off? Apple says that if Photos can’t find the device, it stops using that library and creates a new empty one in Pictures. Turn the NAS on, mount it, quit Photos and choose the old library again with Option held down.

Does AlbumRescue read a library on a network share? We have not tested that. Copy the library to a local drive and scan the copy.

Does the scan change my library? No. AlbumRescue only reads, from a private copy of the database.
