J. Dempsey (Creative Guy) created a list of free online storage sites that takes a good look at a variety of online file storage sites.
Online file storage is a great way to backup your computer and web pages, as well as your images. Some sites specialize in storing photographs and images, mostly for public viewing, but still serving a similar purpose.
Having spent too much time with computer crashes, it is critical to find more than one method of storing your backup files. Many just put their backups on CDs or DVDs and call it safe. Try more than one version of storage media. We use flash drives, CDs, DVDs, and removable/portable hard drives, but I’m considering online storage so this is a good reference list.
To use such a service with WordPress, make sure the online storage service’s file size limits exceeds the size of your WordPress backup file (preferably 3 to 5 times as you should store at least 2 backup versions with 3 being the magic number). Then back up WordPress, including the database, core files, Plugins, and Themes to your hard drive. Then upload it to the online storage service of your choice.
Ah, safe and protected. You hope. 😉
In a week or next month, depending upon how actively you post, do this again, calling this backup by date or number 2. In another week or so, do it again, calling this backup number 3. In another week or so, do it again, but this time, call it backup number 1, replacing the first backup, or give it the new date and delete number one to save space.
This way, if something happens with backups 1 or 2, you have three to fall back on, losing only a little of your posts and not all of them. But save the backup files to another media type, just to add more protection to your valuable blog.
