Backup is one important task while considering the files we want for the future use. The same applies for the websites especially blogs that update regularly. You never know what catastrophic might happen to your blog, some times bad hosting problems, hackers or any some others. The best defend against all those problems is a good backup. Mostly hosting services backup your files and databases weekly or monthly , but its good to have a copy of the backup with yourself. The people who have access to the back end of the hosting especially Cpanel have backup option there, but what if you have access to only to your blog and your FTP space. Either you have to download all the files manually or use a WordPress plugin to download all the database and files. Now downloading all these manually is a sick job, mostly bandwidth wastage, time wastage etc. What if you can schedule a backup so that it backups all that files and databases to a remote location or any other file storage services like Dropbox. That is where a plugin called BackWPup comes in.
Dropbox is a Web-based backup/file hosting service operated by Dropbox, Inc. that uses cloud computing to enable users to store and share files and folders with others across the Internet using file synchronization.
