I know some don’t like the Cloud for privacy reasons etc., but I’m definitely not going back to manual transfer and backup ever again. On my Android phone and iPad, I use Google Photos. Any time I take a pic on either device, it automatically uploads to the Cloud (you can wait until on WiFi to avoid data charges if that applies, I believe it waits as the default). If I want to look at photos from a Mac, PC, Linux, Chromebook, Android etc., I just go to the Google Photos website via a browser (or app for iOS or Android) and it is already done, the pics are already there, I don’t ever have to do anything.
The Google Photos app can also intelligently clear space from your phone or tablet when the local cache of photos takes too much space. Also, if I want to download pics to my own permanent home storage device from the Cloud, I can still bulk download pics from Google Photos if needed. If I want to view or share pics with others, I can easily do this from any device that has access to the Internet from anywhere (share albums, individual photos etc.).
I do the same for Music. All my digital music (legacy mp3 etc.) has been uploaded into Google Play and I can listen from my phone, Jeep (Android Auto), office PC, home Mac, Linux, Chromebook etc.
