I’m a bit chuffed with my scripting efforts in ESXi, so I thought I would share, I hope someone else might find this useful.
To give a bit of background, I run a VMWare Hypervisor ESXi server, it’s only a free license version single host, so most of the backup software doesn’t work that you can buy. But I have found an awesome script called ghettovcb that utilizes the snapshot and VM console commands to make VM running (and off) backups of my guest VMs. But obviously I want to get this data off the host, this is where ncftp comes in.
Now I found the code I needed to write to get all my machines backed up and transferred was crazy, and to get these two to work together.
Writing this, I’ve just thought I should code up all the commands into a single script file, maybe that’ll be next. But the below allows you to state a single VM’s backup folder, or a list with the “-f textfilewithvmsperline” command, which I’ve been able to use the same list from ghettovcb, so I know, if it’s backed up, it’ll be uploaded also.
Well, shout out if this has helped you.
