It’s amazing how often some Lightroom users still assert that a disadvantage of the DNG file format is that any time the metadata changes in the DNG file, you have to backup the whole DNG file again (and again). This isn’t a disadvantage of DNG – it’s a failure to re-assess and think through your backup strategy.
So as it’s now pantomime season, a deep intake of breath please, and after me – OH NO YOU DON’T!
To explain, I don’t dismiss the need to back up your work. Backup is good, of course, but you have to think it through and ensure it is appropriate.
A false sense of security
Let’s say that you did decide to back up the DNG any time the metadata changes. One obvious downside is that repeatedly backing up the image is going to put a strain on your backup resources.
But the more fundamental problem is that these more…
Why does the second copy upon import go into a folder called “Imported on November-11-13” and not into a folder named to match the folder on the hard disk that was set as the Destination for the import?
David Marx’s Professional-Grade Backup Plans is worth reading.
My one point of minor difference is that people spend too much time thinking about their backups, making sure everything is backed up – but don’t spend time ensuring they know how to use their backup software’s restore features.
Too often people only try to figure out how to restore data when they’ve just experienced a catastrophe. Do a dry run.
If you save metadata back to a DNG, doesn’t it mean that every time a change is made the whole large file needs to be backed up?
Not really. It obviously makes no sense to keep backing up big DNG files after every change, but that’s a straw man argument against the format. Instead you simply backup the DNGs upon their creation, and routinely backup your catalogue. If you were to hit a catastrophe, you can reconstruct the exact state of your work by restoring these virgin DNGs and your catalogue. Sidecars don’t contain all your Lightroom work.
There’s a funny bug in Lightroom on Windows when you try and select a folder or drive:
When I try to export a selection of images from LR using Specific Folder (or choose folder later) the only available location that shows up in the hierarchy is my Desktop. No other folders/drives are visible. I had this problem once before and managed to resolve it but don’t recall now what I did. I’ve tried shutting down LR and restarting. Rebooting the computer and restoring the default export presets. If I select Export as Catalogue, then my entire folder/drive hierarchy is visible. Using LR 3.5 on Win7 Pro 64.
It is usually triggered when a lot of files are on the Desktop, and you can try this. In the folder dialog, at the bottom you can type “D:” or whatever, and doing so once usually resolves the bug.
