Which wordpress plugin can Use to automatically backup my wp blog to local storage or google drive
Use UpdraftPlus to create automatic backup of your blog
It is a free WordPress backup plugin. It allows you to create complete backup of your WordPress site and store it on the cloud or download to your computer.
The plugin supports scheduled as well as on-demand backups. You can also choose which files to backup. It can automatically upload your backups to Dropbox, Google Drive, S3, Rackspace, FTP, SFTP, email, and several other cloud storage services
UpdraftPlus also has a premium version with add-ons to migrate or clone site, database search and replace, and multisite support among other things. The premium version also gets you access to priority support.
I think this is the best backup plugin, because I found it very easy to use. but since drive backup is what you are looking for, I’ll suggest you create another g-mail account that you can dedicate to the backup process only.
