+1 for me here.I heard that flickr removed many accounts with no apparent reason. Figure it out, all info was permanently deleted.
Consequently, I have many photographer friends which are quite afraid to keep their raw files on some other website. Plus, it was another online service which over night they changed their EULA and terms and conditions, then next thing you know, all your files are being sold to 3rd parties for additional profit.
I think investing in external HDD is the best solution
