A full backup is backup represents backing up of all of the files on of a systemcomputer machine (in our case, a VM). Since it may take a long time, this A full backup is NOT should be performed on a daily basisat the end of each lab or assignment working session.

 In this lab, we We will expose you to use the '''dump''' and '''restore''' utilities in order to perform full backups of your VMs. You should be using this utility same method to perform a full backups of all of your VMs (both lab backup for these labs and assignment) prior to leaving your OPS335 lab sessionassignments.

#From Refer to OPS235 lab2 on backing up your vm1 machine, make a cloned virtual machine called '''backup-test'''#On your host machine, run VMs using the following commandsgzip command [https:<br><source lang=bash>mkdir -p /backup/fulldump -z100 -f /backupwiki.cdot.senecacollege.ca/fullwiki/backupOPS235_Lab_2_-test /var/lib/libvirt/images/backup_CentOS7_-test.qcow2</source>_HD2#When the backup operation has been completed, issue the following command to determine the file-typePart_1:<br><source lang=bash>file /backup/full/backup_Backing_Up_Virtual_Machines OPS235 Lab2 -test</source>Backing up VMs]#What is type of file is this?
