It is better to transfer them to the so-called "cloud" -Google play store can offer you several applications-everything you upload to the "cloud" stays there! It is a large space full of servers - remember what Central Station looks like - Sofia - it's not just about the building - it includes entry and exit points - tracks, arrows, platforms! Now let's assume that there is no station in this place! There is a huge building, which is guarded by round-the-clock security, and armed, there is a high fence, also cameras, when entering you go first through the outer guard and with a pass, you get to the building itself, again goes through the security with a pass, then comes to the servers themselves, which as we know, had to be maintained around the clock! They consist of arrays made up of hard drives — before a drive fails, the information is transferred to another disk in advance, when replacing the defective disk with a new one, the information from this disk is transferred to the new one, replaced with the defective one - this is done in order to avoid information loss! Defective disks are inserted into a press to be crushed in order to destroy the information - all employees are required to follow the rules of operation - not to have access to information from the server - billions of files from around the world are uploaded here around the clock - photos, videos, music, documents! You can be absolutely sure that if you upload the photos, they will stay there until you decide to remove them from there, ie this is exactly the "cloud". -connection with a remote server-necessarily these sites are built in remote places-mostly in the desert and as far as possible from water bodies-any flood is a serious risk of losing everything! In deserts, servers are underground because they need to be cooled, and as we know, underground is colder than the surface! Google's servers are on the surface, for example, but they're in America anyway, but they're remote-do you have a Google photo on your phone-can you upload them there or on Waistra-it's a "cloud" with no space restrictions and it's completely free! And the maintenance technician walks with one skateboard, because it takes time to go around all the servers - a signal is sent to one control monitor that a disk is defective and must be replaced with a new one immediately! So act!

After reading your topic, I also thought about your question. You can read this article, which has the correct answers to your questions http://news.pcstore.bg/2016/10/11/nositeli-srok-godnost/ In short - SD-cards have a shelf life of about 25 years if are recorded once and retracted without being used again. But there is no guarantee that after these 25 years there will be a device on which to rely, because everything changes very quickly. Like finding floppy disks now. I do the following - I have set aside a folder with photos, documents and everything else that I considered important and regular and straight back-ups on other devices. In my case on external hard drives, because this folder is already over 100 GB. I currently use three such hard drives, one is permanently attached to the computer and I do everything on it, and the other 2 are older and are only for back up. I can tell you, this is the safest way to store information permanently. I have things from 15-16 years ago that have experienced several computers, countless operating system crashes, hard drive crashes and more. Do not rely on only one medium, and also never hang the operating and back-up disks at the same time, because the second ones can go together if you have a virus.
