3. Backup

Machines’ backups are executed manually by operators after every significant change.

4 USB disks are stored at the Medicina station with labels on them indicating which of the 4 machines they backup, each disk is partitioned exactly as the original one and can be substituted in the server for a quick reboot in case of failures.

For executing the backup simply connect the USB disk to the corresponding machine and run:

[root@escsSomething]# ./root/bin/doBackup

This will invoke rsync on each significant filesystem partition. if run with –boot option the script will also add labels to the filesystems, and this should be done only during the first backup operation on the disk.
