As an example Google photos is free and will automatically sort your photos such as by location or by who's in them or where they took place or whatever. Technically data-at-rest should exist in three locations on the device it originates or is being used from on a remote backup and on a physical backup, but if you have to choose only to the remote backup is a much better option than the on-site physical backup, which would be the SD card.I agree but you have to pay considerably more than just buying extra storage from eBay or somewhere else. Plus if you have an accident like I did when I fried my V20 in the Carribean Islands you can still recover those files that haven't been backed up to the cloud. Extra little security. Plus with SD cards you can buy one for a trip and label it for that trip and only those files will be on that card. That's what I like to do on vacations. Much easier to organize for me.
