ghettoVCB is a script that allows VMware ESXi hosts to backup virtual machines using snapshots without requiring the guest to shut down.
The drawback with this script is that it is unable to back up guests with existing snapshots.
Installation
Get the script from their GitHub repository:
You may either install it using their .vib package, or save the script somewhere accessible by the ESXi server.
Usage
Create a datastore (either NFS or disk) that you will backup to. For my usual use-case, I normally create a NFS share for backups which is also where I place the ghettoVCB script and configuration as well.
## /data/vm is exported for the ESXi server.
## Edit the ghettoVCB.conf as desired (optional)
## The backup_vms file contains all the VMs I wish to back up (see below)
leo@nas:/data/vm% ls
backup_vms esxi-backup/ ghettoVCB.conf ghettoVCB.sh*
leo@nas:/data/vm% cat backup_vms
CentOS 7 Web
Fedora Compute
To back up a machine named 'CentOS 7', run:
[root@server:/vmfs/volumes/ee8ff6f0-af4dbc98] sh ./ghettoVCB.sh -m "CentOS 7"
However, if you want to backup a set of virtual machines, create a text file containing the name of each virtual machine you wish to back up and then run:
[root@server:/vmfs/volumes/ee8ff6f0-af4dbc98] sh ./ghettoVCB.sh -f backup_vms
Scheduled Backups
To automatically backup virtual machines on a regular basis, you will need to create a cronjob on a separate server to trigger it.
Set up a root SSH key so that it can log in and run the script.
