Backup to NAS hangs at "Copying Catalog"

[MrAbeFroman]

Hi!  After losing a hard drive to a spilled cup of coffee (thankfully, not a single file lost), I just upgraded to new M1 MacBook Air with Big Sur 11.1.  I have Lightroom Classic version 10.1 installed and working well, except when I backup the catalog to my Synology NAS as I close out of Lightroom, it hangs on the backup at "Copying Catalog".  I've let it run for hours and nothing. 

If I backup to the local SSD everything works great.  Lightroom has no issues accessing the NAS for import and access to the original raw files that I keep on the NAS.  It does seem to start the backup as the NAS will show the dated folder along with the Catalog.lcat file and lrcat-wal file, but it never zips and completes the process.  I found a post that suggested giving Lightroom access to Full Disk, which I've tried, but that didn't seem to make any difference.

I've been manually copying the backups to the NAS without issue, but really want this to work automatically to ensure I always have good backups.  HELP!  Thanks in advance!

Backup the catalog to the local SSD and then Copy and or Move that backup over to your NAS.

Yes, that works, however a backup that is not automatic is not a true backup.  I'd like to actually fix the problem.

As you should know, the backup via LrC just backs the catalog, not the photos.

Better options exist for accomplishing automatic backups.Better options exist for regular timed backups.

Your NAS may have come with such software.

Yes, I understand, I am only trying to backup my CATALOG off the SSD where it resides.  The photos themselves reside on the NAS which is backed up nightly with bi-monthly offsite redundancy.  

This is a simple function that has worked flawlessly for several years.  When I close Lightroom I want to backup the CATALOG to a NAS that I have mounted on my MAC.  I am able to backup to the local SSD, but then my working catalog and my backup would be on the same SSD, not much of a backup.  I would also prefer not to have to wait for Lightroom to backup to the SSD and then manually copy it to the NAS, as that depends on a manual step that is too easy to forget or to be in a hurry and have to wait for.

Did this work on your older machine before? Curious if you've ever had it work this way. This might be a file locking issue. Does it work well if you move files within Classic to the NAS drive or if you import images with a destination on the NAS?

If its of any help to your situation I am using LRC on an iMac and I use Transmit very reliably to backup/sync files to a NAS.

But I'm one version of the Mac OS down from you.

I'm really cautious on updates.

Have you talked to the NAS vendor? Adobe software is notoriously picky about working with a NAS device and there may be incompatibilities or a need to upgrade firmware/drivers.

Until last week I had LR 6.14. Bought me a Fujifilm X100V, and LR 6.14 doesn't read its RAWs. So I upgraded to LRC 10. With LR 6.14 the catalog backup to my Synology NAS worked like a charme. With LRC 10.x I have the samer issue: During copying the backup hangs for 2 to 3 minutes. Then it continues very, very slowly til end. This has to be an issue of LRC. Nothing else.
