Is it possible to make an automatic backup solution that wouldn't rely on the wp-cron, but rather the Linux cron solution? I don't like the fact that users have to wait when the backup is processed and they can not see the website until the backup process is finished.
The idea is to create a passkey for the backup process and whenever somebody accesses "www.myblog.com/?process_backup=backup_name" the backup would be run and it wouldn't affect anybody browsing the website. This way I could put this to the Linux cron with "curl" function and schedule backups any at time and with any frequency I want.
