Hello Apple community!

I have been reading about photo storage solutions with great interest. I understand the rules for moving photo databases (Apple file system, non-Time Machine media, no NAS). In my case, my purpose is simply thatBusinessMy NAS backups (without access) will re-copy the NAS photo database to the appropriate media if the unthinkable happens - catastrophic data loss. I'd do it empirically, but my database is a reasonable size (>80GB) and I'm working over WiFi so it takes a long time before I get real results - so far I've successfully copied the photo database to the NAS, but nothing The ability to verify is there or database quality/corruption problem. I appeal to all users who have experience with copying a photo database from NAS storage to a suitable medium. Do you have any questions? It's about setting up secure storage for my photo database, and a NAS might be a reasonable solution (along with +1 or 2 external hard drives).

Thanks in advance everyone,

  • Apple Photos replacement. Unfortunately, Apple engineers do not understand NAS technology. So, what are some good third-party Apple Photos alternatives that can be used to store photos on a NAS and sync them to an iPhone? I am not interested in permanently renting storage space from Apple to use iCloud 3323
  • iCloud Photos update has no visible progress. I'm trying to sync my photo database between an iPhone (running iOS 15.1.1) and two Macs (running MacOS Monterey 12.2.1). On one of my Macs (new MacBook Pro with M1 Pro) the Photos app seems to keep "updating" and doesn't reflect the changes on the other two devices even after a week. The fact that the system file size of the photo database has not changed raises the question of whether this helps at all. For reference, here's what each device shows: iPhone35,413 photos3,584 videos "Just updated" on Mac 35,334 photos3,571 videos 257.65GB* Seems to be stuck in the MacBook Pro system photo database "Photo Library" Live "Updating ... .” (does not reflect iPhone) 35,449 photos 3,578 videos 108.72 GB in system database Photos Library.photoslibrary file *Note: ^^^ These values ​​do not appear to have changed *iMac and MacBook Pro are reported to the same iCloud account and has the photos setting "Optimize Mac Storage" which makes the big difference between the system photo database files very strange.I read some posts that said you should "just wait" for very large photo databases, so I did. But it's been at least a week. I've set the MacBook not to sleep and left it connected to ethernet, showing upload and download speeds of around 100MB/s. Nothing noticeable has changed. FYI, when I take a new photo with my iPhone, it shows up in photos on my "just updated" iMac, but not on my "updated" MacBook Pro. That looks suspicious. I have other photo databases that need to be imported and merged, so the MacBook Pro stuck on "Refreshing..." keeps asking me if I have a problem that a long wait can't solve? If so, is there any other solution or solution? I'm tempted to wipe the database and copy it from the iMac, but I'm worried that the MacBook Pro actually has some photos/videos that the other two devices have (or iCloud), and if I do that, I might lose those photos/videos. Any advice is greatly appreciated! 3582
  • The safest way to backup your offline photo library Hi, when I look at the Activity Monitor, I see that the "photolibraryd" daemon is often processing the photo library in the background, even when the Photos app is closed. Apple's support article states that if you want to back up your photo library by copying to another volume by dragging, that's fine. However, I am wondering if the photo library task reads intermittently, is the photo library task always in a consistent state and ready for backup. We have a 1.5 TB photo library that is not synced to iCloud and we back it up to a Unix TAR archive. I expected the same problem here, namely that the library is not in a consistent state when accessing its files for backup. Do you know any way to get proper backups? I also use Carbon Copy Cloner and should have the same problem. So far, the only option I can think of is to move the photos to another library before backing up the main library. We restored our library from a TAR backup and our library still works, but there are long delays between operations and frequent heavy disk activity. We also rebuilt/repaired the library, but that was very slow (1-2% CPU usage), and when it was done, latency only improved slightly. We store the library on a standard Western Digital external USB hard drive formatted with APFS. Thank you! 1188

You still need a properly formatted drive so that data structures and permissions can be set appropriately.

The only way I can think of is to use Disk Utility to create a disk image on a network drive and then format the MacOS Extended disk image. Even then, you'll need to check yourself to see if there's a reliable backup there. The only option is to restore it to a compatible volume and test it.

I'm still not trying to open the library when it's stored online.

You can use a wired connection to test the copy on the NAS, and you can also use a wired connection when moving the library. Just don't touch the library while accessing the NAS remotely.

However, a wired connection is not Ethernet. Only if the NAS has USB or Thunderbolt.

Bok Tony,

Thank you for your reply. I noticed your "do not touch" database (emphasis mine). If I'm the only user of the NAS and don't share this photo database, can I mitigate some of the risks of storing it on the NAS? I work hard to ensure that I fully understand the requirements and risks so that my expectations are met if the unthinkable happens.

I thought about it further last night. For example, when I use Timemachine to back up my photo database, I get the benefits of incremental backups (versus copying a large photo database with each backup). But if I measure the NAS, is there still the same risk of directly copying the photo database?

To illustrate, my current photo database (<100 GB) is on an SD disk. I have an external hard drive available, but I would like to have one original photo database and copy/copy the images to the hard drive (instead of updating multiple hard drives). I realize that Timemachine won't solve the problem, but I see Timemachine as an extra layer of insurance (if I can mount a photo database and back it up to a NAS).

Thank you very much,

Greetings, Leonie!

I noticed your comment about not touching the library while going wireless. I describe my situation in my reply to Tony, and the more I think about whether wiring is the way to go:

  1. Copy the current photo database from the SD hard drive to an external hard drive
  2. Connect an external hard drive to the NAS via USB3 and copy it to the NAS share
  3. Don't touch the database (it's easy, just for storage)

As mentioned, I'd rather avoid doing this regularly unless the Finder is smart enough to just copy the updated database items (not sure how it does that since the database is a single file).

A possible solution would be to copy the time machine photo database to an external hard drive and copy the sparse files to the NAS (remotely or via USB to the NAS)?

Thank you very much,
