1'''2Created on Apr 10, 20133The python script have been developed to:4 1. Perform a backup the last Sunday on the month5 2. Notify to staff about the backup and estimation time of the down services 3 days before (Thursdays)6 3. To Perform all the backups using libvirt and scp command.7After a backup the result will be:8 1. One new folder with the domain server name9 2.
