Include all Scheduled Tasks (cronjobs) to Backup of Server configuration
Now Backup does not restore scheduled tasks because cronjobs are not in Backup of Server configuration.
Imagine if you have 150-200 cronjobs what you have to enter manually after every server re-installation.
Thanks for raising the problem. The function has been delivered in Plesk 11.5
You can check CloudBacko Pro Software (http://www.cloudbacko.com/) for backup. CloudBacko backup all servers, databases, virtual machines & workstations. CloudBacko Pro will keep backing up your data in the background continuously. When your computer is busy with high CPU usage or network traffic, backup will automatically be paused so as not to affect the computer's performance. I hope you can try this software too.
