The zip file is part of the backup now, more space and less confusion when opening a backup in place of the regular catalog! I don't believe there is a way to stop it?
I also backup to a network location and do not get the temp file, could a setting be causing this on your drive? I agree it is slower than a local disk but that is the nature of the NAS.
None that I know of or heard of. And looking at the Back Up dialog window there doesn't seem to an option.
But in any event you should be doing full system backups on a regular basis to some externally connected drive/system whether that be an external drive connected directly to your computer or to some type of network storage system. Those backups would take care of backing up the backups of the LR catalog.
Thank you for that. I looked all over the options too! I can see the temp file being created (and it gradually gets bigger) if I monitor the network drive whilst Lightroom exits - it then disappears to be replaced by the .zip file (presumably renamed) once the process finishes.
I do backups to the network drive - but now I have to add another step into the Lightroom exit process. Just a pain that they have chosen to implement the zipping across a network (something that we were always advised not to do when I was working!)
Actually what LR is doing is first copying the catalog then it compresses it then saves it to the desired, selected location.
You could always set LR to not backup the catalog then use some other program to sync, Auto backup, the actual LR catalog file on a daily or weekly basis or do it manually. The only problem with some other program doing that is if the LR catalog is open it might also copy the .lock file if you set it up to copy the complete catalog folder.
As mentioned I would suggest it is your system somehow.
There have been no reported issues and I have my system to do the Back Up to another drive which of course it should be and it is not slow.
What type of network do you have???
