How To Back Up And Keep Your Lightroom Images Safe
Backing Up the Library
An option in Lightroom’s General preferences allows you to create an automatic scheduled backup of the master Lightroom library file at a frequency of your choosing. I strongly advise selecting one of these options, in order to gain an extra level of built-in backup security that may well prevent you from losing valuable library data information.
When you select a scheduled library backup option, the dialog box in Figure 1 appears each time a scheduled backup is due. You can specify a location where the backup library file should be stored, as well as run a test to see whether the database is corrupted. If the file is corrupted, Lightroom offers the opportunity to replace the current (corrupted) database with the previously backed-up database copy file.
Figure 1 Lightroom asks you to confirm that you want to back up the library.
