Storing website backups on a different server than the one hosting the website itself is a long-accepted industry best-practice. XCloner makes it simple to send backups to the remote-location of your choosing.
Unlike many backup plugins, XCloner includes many popular cloud storage services such as Google Drive, Amazon S3, Microsoft OneDrive and Backblaze to name a few. And since many of these services offer free plans with ample storage, many website owners can use XCloner to build a totally free, offsite backup storage system.
XCloner also supports most servers in a generic way by allowing backups to be performed via FTP/SFTP and WebDAV.
You can review all the storage locations along with detailed usage instructions in the XCloner documentation.
