Info

This the basic Backup configuration.

Your server is going to receive daily backups, on the selected hour and minute.

The backup plan is optimized to have the minimum overhead to your system, while maintaining a high performance restore system.

The most time consuming backups will be on the selected day.

You can specify a set of files you want to backup from a list of preselected Fileset

You can alter this configuration later on according to your specific needs.
