Does Backblaze backup my .lrdata files in Lightroom?

To avoid unnecessary use of your bandwidth,  Backblaze will not backup Lightroom's preview files.  These files (.lrdata) are recreated previews for Lightroom whose purpose is to make loading and viewing Lightroom photos faster, but they do not contain any unique user data.  As such, these files are excluded from backup to save bandwidth and space.  If disaster strikes and you need to restore your Lightroom files, the .lrdata files will automatically be recreated from the other Lightroom files (.lrcat).
