Can anyone recommend a portable backup and editing device that I can use on a photography trip to Icleand in March? I found the GNARBIX on B&H where reviews were good. My small laptop I used last in 2019 is a windows 7 device that was slow than and obsolete now. My goal.is to backup and view pictures addi.g as little weight to the camera bag as possible. I plan to have 6 SD cards with me for the 8 day trip to Iceland. Want to protect my experience!. The group has been very helpful in preparing me for my trip. Thanks in advance for any input.

You've already gotten lots of good advice, particularly from CHG_CANON who, IMHO, is the resident Lightroom Classic expert.

Only a few things to add - One, don't be very worried that you'll mess things up with Lightroom Classic. Every visual change you make to a photo is recorded in a separate file so that the original photo remains unchanged. (Note that changes to EXIF data, like keywords or dates are recorded in the physical file.) It is possible to delete a photo permanently, but when you ask Lightroom to delete a photo, it will ask you if you want it deleted from the disk drive or just removed from the catalog. If you do the latter, the photo remains on your disk drive but you just won't see it in Lightroom Classic. You can always import it into Lightroom Classic again later.

Two, and this repeats what others have said, your actual folder structure and naming conventions that you use on your disk drive for the folders and files is not very important. The only situation under which that becomes important is if you were to stop using Lightroom Classic because then you will need to rely on that folder structure to find a particular photo.

And, lastly, Lightroom Classic gives you many orthogonal ways of organizing your photos. By orthogonal I mean that each way you organize is independent of the other way and each way you organize is hierarchical in nature. The first one of these is the actual folder structure. But because there are so many other ways to organize, it becomes less and less important. Another way to organize is to use Collections. Although a photo can be only in one physical location, e.g., a folder, it can be in many Collections. Collections can be grouped together into Collection Sets so that they also behave in a hierarchical fashion. Another way to organize is through keywording. Keywords can also be hierarchical. For example, I have a geographical set of keywords with countries at the highest level, then states or provinces, then cities, and in some cities particular buildings. As a result, when I assign the keyword Philadelphia to a photo, it automatically also gets the keywords Pennsylvania and USA. Finally, you can use Labels (shown as colors) and Stars to organize photos. How you use them is up to you. The advantage of these two organizing tools is that using them is very fast, a click or two per photo. Say I want to pick out 10 photos to send to someone, but I have several hundred to choose from. If I'm not currently using the yellow label, I might use that and as I browse through the several hundred candidates on my first pass, I can quickly label a subset with yellow. Then I filter to see only the yellow labeled ones and discover that I've still got 23 candidates. Now it is easy to compare these 23 with each other, and remove the yellow label from the ones I rule out until I eventually get down to the 10 I want.

Just to clarify, for this post and for the OP:

Our OP should confirm the use of LR 'Classic', literally the Classic, desktop, full-function, catalog-based software. The "LRCC" software is now the browser-based software that has been renamed yet again as simply "Lightroom". None of us can control Adobe's determination to make this all confusing. But, we certainly can use the clear and exact product names to avoid still more confusion.

For the comments above, LR (I only mean LR Classic from this point) only does what the human driving the computer instructs the software to do. The software only creates folders as the human instructs. Of course, there are a lot defaults to be managed by the human, sometimes maybe making it seem like the software does its own thing. But no. It only does what the human tells or allows it to do.

Everyone can manage their folders and filenames as best fits their unique needs / approach. But, when you rely on a simple foldering approach and begin to interact with your files only from inside the LR Library (catalog), you begin to realize you don't need to know the filenames nor the folders. There's no reason to do the same work twice, both inside and outside LR. Rather, just add all your descriptive data about individual images and the whole shoot inside LR. Your metadata filters let you find images by shooting date or any number of filtering attributes populated into the catalog when the images were imported. If you want descriptive filenames, consider adding those as-needed when you export the edited results.

LR is a very different way of thinking about your images. Many of us have spent 20 / 30+ years building folder structures and best practices for how to organize and find our files with nothing more capable than a OS 'explorer' search tool. LR is a relational database that captures all relevant data from the image (camera) file as well as all the descriptive data you add via LR keywords and collections. If the data is inside the LR catalog, you can search, sort and / or filter by those image attributes. LR is much much more powerful. You just need to unlearn using the OS tools and work inside and trust LR. Entirely.

I will just throw my $.02 in here about importing. I use an external drive for my photos, so how I do it, is create a folder for the year and name it Master Catalog 2022, then create folders for each month in there. Then when I do a shoot (I do landscape photography) I create a folder for the location. I copy all the photos from the SD card into the appropriate folder, then I import from that folder on the external drive into LR. If for some reason I ever need to move my images (which I have), having them all nested under a year makes it easier to point LR to the missing images. Anyway, that is just how I do it, which doesn't make it right or wrong, just another way to do it.
