According to the samba.org website: ''"Samba is the standard Windows interoperability suite of programs for Linux and Unix. Samba is Free Software licensed under the GNU General Public License, the Samba project is a member of the Software Freedom Conservancy."'' Although a Samba server can provide many features such as printer sharing and backups, this This lab's primary focus is to set up a Samba server on a Linux server in order to allow MS Windows users to share common files from the Linux's Samba server.

*#Create a file in that directory, then switch to '''vm2''' to confirm that it was created.*#Use umount on '''vm1''' to unmount that directory.*Note that this tool would leave the directory mounted until the machine rebooted or it was manually unmounted. It would also allow other users access to the directory, as it effectively became part of the local filesystem. It could even be added to fstab to be mounted on boot (if it didn't need a password).

You should be using the dump or rsync command, and you should use the Bash shell script that you were adviced to create in order to backup all of your VMs.}}
