Not much. My up speed is 60 kbps. My company uses “source safe” which every software development company uses, so all my work is backed up on a server.
I do download my Gmail accounts but I leave copies on the server. I delete every so often tho.
Music, photos, videos, personal documents are all on my machine.
My mail is in the cloud, I stream music mostly from Spotify so I have packed away most of my cds. I have long since stopped buying software on physical media so you might say my software is in the cloud as well.
I use various services to keep some files accessible between devices, and my phone automatically uploads photos to Dropbox.
Contacts and everything else on my phone is backed up to Google.
I would certainly use cloud storage more if I had better up speed than I have now. I’d like to have remote copies of the photos I take with my dslr, but they are in raw format and would take forever and a half to upload.
And I don’t mind using the word cloud. To me it just means external storage that someone else is responsible for the upkeep of.
