I believe this file has something to do with the new masking feature introduced in LrC version 11.
If "automatically write to xmp" is selected " is the info also written to xmp sidecars and to DNG files?
See the relative screen captures.

So making backups of the Backup created when exiting LrC is the best way to ensure you have a full and optimized copy of the Catalog Data needed to restore a corrupt Catalog.
I'm not sure why you should make backups of that backup in order to do that. If you mean that Lightroom creates the backup inside its own catalog folder, which could mean you lose your backups too if your disk crashes, then be aware that you can change the location of the catalog backups in the dialog that asks you if you want to make a backup.

Yes.
Note the the LR backup at exit (when invoked) already does that. The backup zip file contains both, the .lrcta and the .lrcat-data.
Thanks Philippe, I am aware of that as indicated in my original post.

Yes, I understand that and my backup already sent to a alternate location than the Catalog. That folder is regularly copied to an external disk.
