→Backups (Rsync)
= Backups (Rsync) =
In OPS235, you learned to use the '''gzip''', '''gunzip''', and '''virsh dumpxml''' / '''virsh define''' commands to backup your virtual machines and the '''tar''' command as an archiving tool.<br>In this course, you are taught other more practical methods of performing backups for Linux systems including:*'''cpio'''*'''dump''' / '''restore'''
In this lab, we will focus on a method to provide automatic backups of your VMs to your host machine as opposed to performing full and incremental backups (although it is recommended to study these techniques since they may be useful at some point in a later lab, and will be useful in later courses). We will now focus on using the rsync command for backing up our VMs.
'''Rsync''' is a very versatile backup tool. As the name suggests, rsync is used for <u>synchronizing</u> files typically across a network. It works over the '''SSH''' protocol, which is useful in our situation since we are running ssh on our server and VMs. You are going to use your ''host machine'' to backup files from the ''virtual machines''.
