Lightroom Classic: Backup 'extended attributes' prevent backup software working
I have a problem trying to get lightroom catalog backup files backed up using my backup software LiveDrive. The people at LiveDrive tell me that the files cannot be backed up because they have 'extended attributes'.If I unzip and re-zip the backup then it gets backed up OK, so clearly there's some difference between the zip files created by Lightroom and those created directly by Windows.Can anyone cast any light on this? I'm tempted to just write a powershell script to remove extended attributes, but not sure which would be safe to remove (would Lightroom be able to restore properly afterwards), and not entirely sure which would need to be removed to allow the backup to happen anyway.

The T attribute on Windows files is described by Microsoft as:
"The file is temporary. A temporary file contains data that is needed while an application is executing but is not needed after the application is finished. File systems try to keep all the data in memory for quicker access rather than flushing the data back to mass storage. A temporary file should be deleted by the application as soon as it is no longer needed."
It seems sensible therefore that backup software ignores these files, but I want my Lightroom backups backed up to my cloud storage.
I have worked around this for now by running a powershell script to remove this attribute as part of my backup process, but this should not be necessary.
This was not happening on earlier versions of Lightroom - the earlier files do not have this attribute set. It has taken several weeks in discussions with my backup software vendor to work out why my Lightroom backups were no longer being copied to my cloud storage.

I make regular backups of my Lightroom catalogue. I also like to have my catalogue backups included in my system backup. However, when Lightroom creates a backup of the catalogue, the zip file has the "temp" attribute set. Quite understandably, some backup software (including mine) will ignore files with the temp attribute set, so the catalogue backup is not backed up.
Thanks for reading,
Brian

While I'm not aware of any issue this causes for Lightroom itself, it does cause Amazon Drive to deem the file temporary (because it is) and skip the sync that would otherwise occur:
The behavior exhibited by Amazon Drive is definitely reasonable, and is not exclusive to it. I'm sure plenty of backup services will ignore temporary files since a file marked this way should be temporary.
When Lightroom finishes its backup, it really should remove the "temporary" filesystem attribute since the file really isn't temporary anymore.

I'm having the latest version "7.3.1", and now I can't backup my files (with Synology Drive).

When doing a backup of my catalog (when exiting LR), the file keeps the attribute "Temporary" set after the backup is done.
That means that I can't do a backup of the file (done with Synology Drive).
I'm having the latest version "7.3.1".
It's a old known problem, there has been fixed previous.
