I use dropbox, costs about 6 squid per month and I get access on my mobile too if I'm out and about and want to look at something. Also lets me share between machines and I can invite people to share certain folders which is handy for clients too.
It backs up continuously so I dont need to remember to do it, I was using idrive but this only backed up and did not let me share with others or if it did wasnt as easy as dropbox.
I get 100bg of storage which may or may not be enough for everyone's requirements.
A laptop went kaput on me years ago and I lost a couple of days of data which was lost time and money to me, I've made sure that never happens again!
