I have a large library (over 300,000 photos) and my Lightroom catalog folder is over 160GB. This is important for me to backup, but the current process changes the name of the catalog and folders. Once changed, my backup process deletes hundreds of thousands of "old" preview files, and then copies those exact same files back to the target. This is unnecessarily complex, time consuming, and tedious--Lightroom can ensure the catalog name is the same when it completes the upgrade process. Consider those (like myself) that are sending this data offsite for backup--the cost savings, time savings, and bandwidth savings make this change necessary.
I am currently performing these steps manually by renaming the catalog file and supporting folders before opening the new Lightroom version, but Lightroom could do that automatically for me without too much extra work.
To help the average user, most of the people I teach Lightroom, or help with their workflow don't even know where their PICTURES are, let alone how to manage their catalog. An automated Adobe solution of renaming the old catalog file for backup would be awesome and simplify the process for the user.
- Install the latest version of Lightroom
- Open the default/last catalog file as usual.
- Lightroom prompts to confirm upgrade (no naming option needed) in the dialog box.
- Lightroom names the existing catalog file the -Vxx which matches the catalog old version compatibility level. (catalog-v10.lrcat) Also rename all the supporting folders to match (Helper, Previews, Smart Previews, Sync, etc.).
- Lightroom upgrades this -Vxx catalog and names it at the current catalog name. (catalog.lrcat). Upgrade as usual, which updates all the supporting folder names, too.
The backup program would only see files that changed modified date/time, would copy over the catalog and anything new, and would be quick and efficient. The user who has been opening "catalog" all along doesn't change anything--they still open the same (upgraded) file.
