Today’s Question: Do you recommend backing up the whole Lightroom presets folder (Appdata > Roaming > Adobe > Lightroom)?
Tim’s Quick Answer: Yes, it is a good idea to back up the full Lightroom (Classic) folder where the various presets are stored by default, just to make it easier to recover should anything go wrong with Lightroom Classic, or you need to transition to another computer.
More Detail: By default Lightroom Classic stores a variety of presets and templates in a “Lightroom” folder that is somewhat buried in the operating system. For Windows users the folder is in the Users > [username] > Appdata > Roaming > Adobe folder structure, while on Macintosh it is in Users > [username] > Library > Application Support > Adobe structure.
The “Lightroom” folder in question contains a variety of additional folders where prests and templates are stored. That includes, for example, presets that you create in the Develop module as well as templates saved in the sharing modules (such as Print), among other data.
While you don’t generally need to interact with the files in the “Lightroom” folder directly, you may want to be able to recover those files if you run into a problem with Lightroom Classic or you want to transition to a different computer.
In general, as long as you’re regularly backing up your internal hard drive (where Lightroom Classic is installed) these files should be getting backed up. However, I would confirm that the files are included in such a backup, just to be sure you have a backup in case it is ever needed.
