As a scrapbooker here are mural bits.
Scan and save two two types of media. Ie one copy in the "clouds" one copy at your home on a hard drive, another copy stored offsite on CD, thumbdrive, external harddrive etc. Media does change and deteriorate so you will need to keep on top of creating replacements as needed. By segregating the copis to different locations you tend to protect against disater, virus, etc
I'd also place the hard copies into acid free storage to prevent further deterioration. I'd also find a wayti document who is in the photos. Once that info is lost the need to keep the photos diminishes.
