• The backup scripts are stored in /u3/scripts;

• The log files for these scripts are stored in /u3/scripts/logs; These logs are rotated on dafnenfs from logrotate (check last point);

• The script u2_backup.sh is responsible to create a backup of /u2 in /u3/u2_backup and launch nfs_rsync.sh script to rsync data to nascoda1. The u2_backup.sh script is launched by crontab on host dafnenfs every day (see Table 2 for details);. The script sends an e-mail to andrea.michelotti@lnf.infn.it francesco.galletti@lnf.infn.it to notify the exit status.
• The script nfs_rsync.sh is responsible to rsync the data from the host where it is launched to nascoda1. It sends an e-mail to andrea.michelotti@lnf.infn.italessandrofrancesco.stecchi@lnfgalletti@lnf.infn.it to  to notify the backup exit status. It is launched by crontab on host danteweb and vldafneafp every day (see Table 2 for details);
• The host dafnenfs share /u3/scripts; danteweb and vldafneafp mount that folder via NFS on boot (folder present in /etc/fstab);
• The host dafnenfs has a custom configuration for logrotate present in /etc/logrotate.d/nfs_rsync to rotate log files generated by these scripts. It will rotate all log files every day, keeping them compressed in /u3/scripts/logs/old folder for 5 days.
