I use smugmug.com for galleries, livedrive for storage and mozy for backup.
The least reliable is livedrive, but overall I like it because it offers unlmited storage and uncapped bandwidth, while mozy has 1 megabit upload limit.
Smugmug works very well.
Mozy is not for storage but for backup; if you change a file on your pc it will change on Mozy as well.
