Backup plan

Ok, so when this site was down I was not prepared at all. Literally all the mangas that I was currently reading was on this site and where I left off those mangas was on this site. It was a whole mess. But what was even worse is that I only used this site and nothing else, so when it shut down I was lost and confused. So to prevent that from happening again, I hope that someone, any one can please recommend me some good manga sites.
