Backing Up Your Stuff

I have my personal songs and the songbook for our group stored on my Desktop Pc, backed up on my two Android Tablets and my Smartphone, and a few other copies knocking around on various USB memory sticks. Also stored on my Box account, which the members of our group can access any time they lose or misplace a song! Seems 'safe' enough to me, as the chances of losing the lot seems quite remote.And one bloke in our group will not own a tablet and is almost computer illiterate, so he has the entire songbook printed out on paper; he lugs this colossal songbook to meetings every time!

I've got pdfs, gifs, txts of music on my computer, but other than my usual copying to disk once in a while, I have no specific back up regime for my music. If I want something, I can usually find it online, & grab a copy to disk again.

However, I do have quite a collection of music books on a shelf, so I'd never run out of having something to play.
