Backup your blog today if not done yet. Backing up a blog is very important for every blog owner specially for those people who are running a blog alone like me. I also made a blog post on this topic because one of my friend lost his 1.5 years content when his blog hacked and he had no any backup copy of his blog so it's very important to backup your blog. If you hosting company gives you the access to Cpanel than you can easily do it from Cpanel otherwise there a lot of plugins which can help you to backup your blog. I can't write a long post here on thread so if you wanna know how to backup your blog than read my blog post here.
I'm using two plugins. VaultPress (recommended) which you can read my review here, http://www.cypherhackz.net/archives/2011/04/10/vaultpress-review-ultimate-wordpress-backup-solution/ and WP DB Backup. -cypher.
Not only the blogs should backup. I recommend all critical data in your computer should be backed up. And dont use single computer to keep your backup. There are several free services giving free storage. So maintain at least two backups.
There are many plugins from which you can get back up your content. For view the plugins visit the blog link share in the top.
getting back ups is very importing for your blogs, because if you are getting your back up then how you recover your data once it hacked ? i use cpanel almost to do this
What are the issues? I have been using it for a year now. So far I don't have any problems with Vaultpress. -cypher.
