"Do you back-up your sites often? You should, problems could arise fast..."
Well, today I logged in to one of my most precious sites and nada, niente!! All the posts and pages went missing. 2 years of hard work to garbage can and NOT A SINGLE back-up.
Luckily, Hostgator support was fantastic and they fixed the DB < the problem was with a *broken* DB, so it seems.
1) Installing WP DB Backup Plugin in ALL my sites. Takes 2 minutes to install.
2) Will Back-up ALL my sites (I do a lot of customizations) in a new external hard-drive. This takes a *bit* longer but it's a must to keep track of everything.
Don't fall for it like I did. Back-Up your sites, OFTEN!
