The ghettoVCB script performs backups of virtual machines residing on ESX(i) 3.x, 4.x, 5.x, 6.x, 7.x & 8.x servers using methodology similar to VMware's VCB tool. The script takes snapshots of live running virtual machines, backs up the master VMDK(s) and then upon completion, deletes the snapshot until the next backup. The only caveat is that it utilizes resources available to the ESXi Shell running the backups as opposed to following the traditional method of offloading virtual machine backups through a VCB proxy.
This script has been tested on ESX 3.5/4.x/5.x and ESXi 3.5/4.x/5.x/6.x/7.x/8.x and supports the following backup mediums: LOCAL STORAGE, SAN and NFS. The script is non-interactive and can be setup to run via cron. Currently, this script accepts a text file that lists the display names of virtual machine(s) that are to be backed up. Additionally, one can specify a folder containing configuration files on a per VM basis for granular control over backup policies.
Additionally, for ESX(i) environments that don't have persistent NFS datastores designated for backups, the script offers the ability to automatically connect the ESX(i) server to a NFS exported folder and then upon backup completion, disconnect it from the ESX(i) server. The connection is established by creating an NFS datastore link which enables monolithic (or thick) VMDK backups as opposed to using the usual *nix mount command which necessitates breaking VMDK files into the 2gbsparse format for backup. Enabling this mode is self-explanatory and will evidently be so when editing the script (Note: VM_BACKUP_VOLUME
variable is ignored if ENABLE_NON_PERSISTENT_NFS=1
).
In its current configuration, the script will allow up to 3 unique backups of the Virtual Machine before it will overwrite the previous backups; this however, can be modified to fit procedures if need be. Please be diligent in running the script in a test or staging environment before using it on production live Virtual Machines; this script functions well within our environment but there is a chance that it may not fit well into other environments.
Note: If you have found this script to be useful and would like to contribute back, feel free to donate a cup of coffee ☕😁

See the build documentation here
The following variables need to be defined within the script or in VM backup policy prior to execution.
Defining the backup datastore and folder in which the backups are stored (if folder does not exist, it will automatically be created):
VM_BACKUP_VOLUME=/vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/WILLIAM_BACKUPS
Defining the backup disk format (zeroedthick, eagerzeroedthick, thin, and 2gbsparse are available):
DISK_BACKUP_FORMAT=thin
Note: If you are using the 2gbsparse on an ESXi 5.1 host, backups may fail. Please download the latest version of the ghettoVCB script which automatically resolves this or take a look at this article for the details.
Defining the backup rotation per VM:
VM_BACKUP_ROTATION_COUNT=3
Defining whether the VM is powered down or not prior to backup (1 = enable, 0 = disable):
POWER_VM_DOWN_BEFORE_BACKUP=0
Note: VM(s) that are powered off will not require snapshoting
Defining whether the VM can be hard powered off when POWER_VM_DOWN_BEFORE_BACKUP
is enabled and VM does not have VMware Tools installed
ENABLE_HARD_POWER_OFF=0
If ENABLE_HARD_POWER_OFF
is enabled, then this defines the number of (60sec) iterations the script will before executing a hard power off when:
ITER_TO_WAIT_SHUTDOWN=3
The number (60sec) iterations the script will wait when powering off the VM and will give up and ignore the particular VM for backup:
POWER_DOWN_TIMEOUT=5
The number (60sec) iterations the script will wait when taking a snapshot of a VM and will give up and ignore the particular VM for backup:
SNAPSHOT_TIMEOUT=15
Defining whether or not to enable compression (1 = enable, 0 = disable):
ENABLE_COMPRESSION=0
Note: With ESXi 3.x/4.x/5.x, there is a limitation of the maximum size of a VM for compression within the unsupported Busybox Console which should not affect backups running classic ESX 3.x,4.x or 5.x. On ESXi 3.x the largest supported VM is 4GB for compression and on ESXi 4.x the largest supported VM is 8GB. If you try to compress a larger VM, you may run into issues when trying to extract upon a restore. PLEASE TEST THE RESTORE PROCESS BEFORE MOVING TO PRODUCTION SYSTEMS!. Please note, do not mix uncompressed backups with compressed backups. Ensure that directories selected for backups do not contain any backups with previous versions of ghettoVCB before enabling and implementing the compressed backups feature.
Defining whether virtual machine memory is snapped and if quiescing is enabled (1 = enable, 0 = disable):
VM_SNAPSHOT_MEMORY=0
VM_SNAPSHOT_QUIESCE=0
Note:
VM_SNAPSHOT_MEMORY
is only used to ensure when the snapshot is taken, it's memory contents are also captured. This is only relevant to the actual snapshot and it's not used in any shape/way/form in regards to the backup. All backups taken whether your VM is running or offline will result in an offline VM backup when you restore. This was originally added for debugging purposes and in generally should be left disabled
Defining VMDK(s) to backup from a particular VM either a list of vmdks or "all"
VMDK_FILES_TO_BACKUP="myvmdk.vmdk"
Defining whether or not VM(s) with existing snapshots can be backed up. This flag means it will CONSOLIDATE ALL EXISTING SNAPSHOTS for a VM prior to starting the backup (1 = yes, 0 = no):
ALLOW_VMS_WITH_SNAPSHOTS_TO_BE_BACKEDUP=0
Defining the order of which VM(s) should be shutdown first, especially if there is a dependency between multiple VM(s). This should be a comma seperate list of VM(s)
VM_SHUTDOWN_ORDER=vm1,vm2,vm3
Defining the order of VM(s) that should be started up first after backups have completed, especially if there is a dependency between multiple VM(s). This should be a comma seperate list of VM(s)
VM_STARTUP_ORDER=vm3,vm2,vm1
Defining NON-PERSISTENT NFS Backup Volume (1 = yes, 0 = no):
ENABLE_NON_PERSISTENT_NFS=0
Note: This is meant for environments that do not want a persisted connection to their NFS backup volume and allows the NFS volume to only be mounted during backups. The script expects the following 5 variables to be defined if this is to be used:
UNMOUNT_NFS
,NFS_SERVER
,NFS_MOUN
T,
NFS_LOCAL_NAMEand
NFS_VM_BACKUP_DIR`
Defining whether or not to unmount the NFS backup volume (1 = yes, 0 = no):
UNMOUNT_NFS=0
Defining the NFS server address (IP/hostname):
NFS_SERVER=172.51.0.192
Defining the NFS export path:
NFS_MOUNT=/upload
Defining the NFS datastore name:
NFS_LOCAL_NAME=backup
Defining the NFS backup directory for VMs:
NFS_VM_BACKUP_DIR=mybackups
Note: Only supported if you are running vSphere 4. and later. If you are having issues with sending mail, please take a look at Email Backup Log section
Defining whether or not to email backup logs (1 = yes, 0 = no):
EMAIL_LOG=1
Defining whether or not to email message will be deleted off the host whether it is successful in sending, this is used for debugging purposes. (1 = yes, 0 = no):
EMAIL_DEBUG=1
Defining email server:
EMAIL_SERVER=auroa.primp-industries.com
Defining email server port:
EMAIL_SERVER_PORT=25
Defining email delay interval (useful if you have slow SMTP server and would like to include a delay in netcat using -i param, default is 1second):
EMAIL_DELAY_INTERVAL=1
Defining recipient of the email (comma separated):
EMAIL_TO=auroa@primp-industries.com
Defining from user which may require specific domain entry depending on email server configurations:
EMAIL_FROM=root@ghettoVCB
Note: nc (netcat) utility must be present for email support to function, this utility is a now a default with the release of vSphere 4.1 or greater, previous releases of VI 3.5 and/or vSphere 4.0 does not contain this utility. The reason this is listed as experimental is it may not be compatible with all email servers as the script utlizes nc (netcat) utility to communicate to an email server. This feature is provided as-is with no guarantees. If you enable this feature, a separate log will be generated along side any normal logging which will be used to email recipient. If for whatever reason, the email fails to send, an entry will appear per the normal logging mechanism.
If you are running ESXi 5.1 and later, you will need to create a custom firewall rule to allow your email traffic to go out which I will assume is default port 25. Here are the steps for creating a custom email rule.
Step 1 - Create a file called /etc/vmware/firewall/email.xml with contains the following:
<ConfigRoot>
<service>
<id>email</id>
<rule id="0000">
<direction>outbound</direction>
<protocol>tcp</protocol>
<porttype>dst</porttype>
<port>25</port>
</rule>
<enabled>true</enabled>
<required>false</required>
</service>
</ConfigRoot>
Step 2 - Reload the ESXi firewall by running the following ESXCLI command:
# esxcli network firewall refresh
Step 3 - Confirm that your email rule has been loaded by running the following ESXCLI command:
# esxcli network firewall ruleset list | grep email
email true
Step 4 - Connect to your email server by usingn nc (netcat) by running the following command and specifying the IP Address/Port of your email server:
# nc 172.30.0.107 25
220 mail.primp-industries.com ESMTP Postfix
You should recieve a response from your email server and you can enter Ctrl+C to exit. This custom ESXi firewall rule will not persist after a reboot, so you should create a custom VIB to ensure it persists after a system reboot. Please take a look at this article for the details.
Defining to support RSYNC symbolic link creation (1 = yes, 0 = no):
RSYNC_LINK=0
To make use of this feature, modify the variable RSYNC_LINK from 0 to 1. Please note, this is an experimental feature request from users that rely on rsync to replicate changes from one datastore volume to another datastore volume. The premise of this feature is to have a standardized folder that rsync can monitor for changes to replicate to another backup datastore. When this feature is enabled, a symbolic link will be generated with the format of "
Here is an example of what this would look like:
[root@himalaya ghettoVCB]# ls -la /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/WILLIAM_BACKUPS/vcma/
total 0
drwxr-xr-x 1 nobody nobody 110 Sep 27 08:08 .
drwxr-xr-x 1 nobody nobody 17 Sep 16 14:01 ..
lrwxrwxrwx 1 nobody nobody 89 Sep 27 08:08 vcma-symlink -> /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/WILLIAM_BACKUPS/vcma/vcma-2010-09-27_08-07-37
drwxr-xr-x 1 nobody nobody 58 Sep 27 08:04 vcma-2010-09-27_08-04-26
drwxr-xr-x 1 nobody nobody 58 Sep 27 08:06 vcma-2010-09-27_08-05-55
drwxr-xr-x 1 nobody nobody 58 Sep 27 08:08 vcma-2010-09-27_08-07-37
Note: This enables an automatic creation of a generic symbolic link (both a relative & absolution path) in which users can refer to run replication backups using rsync from a remote host. This does not actually support rsync backups with ghettoVCB. Please take a look at the Rsync Section of the documentation for more details.
A sample global ghettoVCB configuration file is included with the download called ghettoVCB.conf. It contains the same variables as defined from above and allows a user to customize and define multiple global configurations based on a user's environment.
# cat ghettoVCB.conf
VM_BACKUP_VOLUME=/vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/WILLIAM_BACKUPS
DISK_BACKUP_FORMAT=thin
VM_BACKUP_ROTATION_COUNT=3
POWER_VM_DOWN_BEFORE_BACKUP=0
ENABLE_HARD_POWER_OFF=0
ITER_TO_WAIT_SHUTDOWN=3
POWER_DOWN_TIMEOUT=5
ENABLE_COMPRESSION=0
VM_SNAPSHOT_MEMORY=0
VM_SNAPSHOT_QUIESCE=0
ALLOW_VMS_WITH_SNAPSHOTS_TO_BE_BACKEDUP=0
ENABLE_NON_PERSISTENT_NFS=0
UNMOUNT_NFS=0
NFS_SERVER=172.30.0.195
NFS_MOUNT=/nfsshare
NFS_LOCAL_NAME=nfs_storage_backup
NFS_VM_BACKUP_DIR=mybackups
SNAPSHOT_TIMEOUT=15
EMAIL_LOG=0
EMAIL_SERVER=auroa.primp-industries.com
EMAIL_SERVER_PORT=25
EMAIL_DELAY_INTERVAL=1
EMAIL_TO=auroa@primp-industries.com
EMAIL_FROM=root@ghettoVCB
WORKDIR_DEBUG=0
VM_SHUTDOWN_ORDER=
VM_STARTUP_ORDER=
To override any existing configurations within the ghettoVCB.sh script and to use a global configuration file, user just needs to specify the -g flag and path to global configuration file.
Running multiple instances of ghettoVCB is now supported with the latest release by specifying the working directory (-w) flag.
By default, the working directory of the ghettoVCB instance is /tmp/ghettoVCB.work and you can run another instance by providing an alternate working directory. You should try to minimize the number of ghettoVCB instances running on your ESXi host as it does consume some amount of resources when running in the ESXi Shell. This is considered an experimental feature, so please test in a development environment to ensure everything is working prior to moving to production system.

The input to this script is a file that contains the display name of the virtual machine(s) separated by a newline. When creating this file on a non-Linux/UNIX system, you may introduce ^M character which can cause the script to miss-behave. To ensure this does not occur, plesae create the file on the ESX/ESXi host.
Here is a sample of what the file would look like:
[root@himalaya ~]# cat vms_to_backup
vCOPS
vMA
vCloudConnector
This execution mode provides a quick summary of details on whether a given set of VM(s)/VMDK(s) will be backed up. It provides additional information such as VMs that may have snapshots, VMDK(s) that are configured as independent disks, or other issues that may cause a VM or VMDK to not backed up.
[root@himalaya]# /opt/ghettovcb/bin/ghettoVCB.sh -f vms_to_backup -d dryrun

To make use of this feature, modify the variable ENABLE_COMPRESSION from 0 to 1. Please note, do not mix uncompressed backups with compressed backups. Ensure that directories selected for backups do not contain any backups with previous versions of ghettoVCB before enabling and implementing the compressed backups feature.
There may be a situation where you need to stop the ghettoVCB process and entering Ctrl+C will only kill off the main ghettoVCB process, however there may still be other spawn processes that you may need to identify and stop. Below are two scenarios you may encounter and the process to completely stop all processes related to ghettoVCB.
Interactively running ghettoVCB:
Step 1 - Press Ctrl+C which will kill off the main ghettoVCB instance
Step 2 - Search for any existing ghettoVCB process by running the following:
# ps -c | grep ghettoVCB | grep -v grep
3360136 3360136 tail tail -f /tmp/ghettoVCB.work/ghettovcb.Cs1M1x
Step 3 - Here we can see there is a tail command that was used in the script. We need to stop this process by using the kill command which accepts the PID (Process ID) which is identified by the first value on the far left hand side of the command. In this example, it is 3360136.
# kill -9 3360136
Note: Make sure you identify the correct PID, else you could accidently impact a running VM or worse your ESXi host.
Step 4 - Depending on where you stopped the ghettoVCB process, you may need to consolidate or remove any existing snapshots that may exist on the VM that was being backed up. You can easily do so by using the vSphere Client.
Non-Interactively running ghettoVCB:
Step 1 - Search for the ghettoVCB process (you can also validate the PID from the logs)
~ # ps -c | grep ghettoVCB | grep -v grep
3360393 3360393 busybox ash ./ghettoVCB.sh -f list -d debug
3360790 3360790 tail tail -f /tmp/ghettoVCB.work/ghettovcb.deGeB7
Step 2 - Stop both the main ghettoVCB instance & tail command by using the kill command and specifying their respective PID IDs:
kill -9 3360393
kill -9 3360790
Step 3 - If a VM was in the process of being backed up, there is an additional process for the actual vmkfstools copy. You will need to identify the process for that and kill that as well. We will again use ps -c command and search for any vmkfstools that are running:
# ps -c | grep vmkfstools | grep -v grep
3360796 3360796 vmkfstools /sbin/vmkfstools -i /vmfs/volumes/himalaya-temporary/VC-Windows/VC-Windows.vmdk -a lsilogic -d thin /vmfs/volumes/test-dont-use-this-volume/backups/VC-Windows/VC-Windows-2013-01-26_16-45-35/VC-Windows.vmdk
Step 4 - In case there is someone manually running a vmkfstools, make sure you take a look at the command itself and that it maps back to the current VM that was being backed up before kill the process. Once you have identified the proper PID, go ahead and use the kill command:
# kill -9 3360796
Step 5 - Depending on where you stopped the ghettoVCB process, you may need to consolidate or remove any existing snapshots that may exist on the VM that was being backed up. You can easily do so by using the vSphere Client.
First, please review this primer on what is cronjob
The task of configuring cronjobs on classic ESX servers (with Service Console) is no different than traditional cronjobs on *nix operating systems (this procedure is outlined in the link above). With ESXi on the other hand, additional factors need to be taken into account when setting up cronjobs in the limited shell console called Busybox because changes made do not persist through a system reboot. The following document will outline steps to ensure that cronjob configurations are saved and present upon a reboot.
Note: Always redirect the ghettoVCB output to /dev/null and/or to a log when automating via cron, this becomes very important as one user has identified a limited amount of buffer capacity in which once filled, may cause ghettoVCB to stop in the middle of a backup. This primarily only affects users on ESXi, but it is good practice to always redirect the output. Also ensure you are specifying the FULL PATH when referencing the ghettoVCB script, input or log files.
e.g.
0 0 * * 1-5 /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/ghettoVCB.sh -f /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/backuplist > /dev/null
or
0 0 * * 1-5 /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/ghettoVCB.sh -f /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/backuplist > /tmp/ghettoVCB.log
Example - Configure ghettoVCB.sh to execute a backup five days a week (M-F) at 12AM (midnight) everyday and send output to a unique log file
As root, you'll install your cronjob by issuing:
[root@himalaya ~]# crontab -e
Append the following entry:
0 0 * * 1-5 /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/ghettoVCB.sh -f /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/backuplist > /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/ghettoVCB-backup-$(date +\%s).log
Save and exit
[root@himalaya dlgCore-NFS-bigboi.VM-Backups]# crontab -e
no crontab for root - using an empty one
crontab: installing new crontab
List out and verify the cronjob that was just created:
[root@himalaya dlgCore-NFS-bigboi.VM-Backups]# crontab -l
0 0 * * 1-5 /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/ghettoVCB.sh -f /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/backuplist > /vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/ghettoVCB-backup-$(date +\%s).log
/var/spool/cron/crontabs/root
:
0 0 * * 1-5 /vmfs/volumes/simplejack-local-storage/ghettoVCB.sh -f /vmfs/volumes/simplejack-local-storage/backuplist > /vmfs/volumes/simplejack-local-storage/ghettoVCB-backup-$(date +\%s).log
If you are unable to edit/modify /var/spool/cron/crontabs/root
, please make a copy and then edit the copy with the changes
cp /var/spool/cron/crontabs/root /var/spool/cron/crontabs/root.backup
Once your changes have been made, then "mv" the backup to the original file. This may occur on ESXi 4.x or 5.x hosts
mv /var/spool/cron/crontabs/root.backup /var/spool/cron/crontabs/root
You can now verify the crontab entry has been updated by using "cat" utility.

Afterwards the file should look like the following:
~ # cat /etc/rc.local

export PATH=/sbin:/bin
log() {
echo "$1"
logger init "$1"
}
#execute all service retgistered in /etc/rc.local.d
if [http:// -d /etc/rc.local.d |http:// -d /etc/rc.local.d ]; then
for filename in `find /etc/rc.local.d/ | sort`
do
if [ -f $filename ] && [ -x $filename ]; then
log "running $filename"
$filename
fi
done
fi
/bin/kill $(cat /var/run/crond.pid)
/bin/echo "0 0 * * 1-5 /vmfs/volumes/simplejack-local-storage/ghettoVCB.sh -f /vmfs/volumes/simplejack-local-storage/backuplist > /vmfs/volumes/simplejack-local-storage/ghettoVCB-backup-\$(date +\\%s).log" >> /var/spool/cron/crontabs/root

Now you're really done!
If you're still having trouble getting the cronjob to work, ensure that you've specified the correct parameters and there aren’t any typos in any part of the syntax.
Ensure crond (cron daemon) is running:
ESX 3.x/4.0:
[root@himalaya dlgCore-NFS-bigboi.VM-Backups]# ps -ef | grep crond | grep -v grep
root 2625 1 0 Aug13 ? 00:00:00 crond
ESXi 3.x/4.x/5.x:
~ # ps | grep crond | grep -v grep
5196 5196 busybox crond
Ensure that the date/time on your ESX(i) host is setup correctly:
ESX(i):
[root@himalaya dlgCore-NFS-bigboi.VM-Backups]# date
Fri Aug 14 23:44:47 PDT 2009
Note: Careful attention must be noted if more than one backup is performed per day. Backup windows should be staggered to avoid contention or saturation of resources during these periods.
The [ghettoVCB-restore.sh]() script performs a restore of virtual machines backed up using ghettoVCB. Tasks are performed directly within the service console of the ESX(i) server involved in the restore process. Two main use cases are supported:
1) Restore a VM that contains ALL VMDKs on one datastore 2) Restore a VM that has VMDKs located on multiple datastores
In all cases, restored VMs will have VMDKs that reside on the SAME datastore chosen for the restore process. Please ensure that there is sufficient space on the target datastore before attempting a restore operation. In the near future, restoration of VMs backed up using the compression feature of ghettoVCB will be implemented.

Usage: ./ghettoVCB-restore.sh -c [VM_BACKUP_UP_LIST] -l [LOG_FILE] -d [DRYRUN_DEBUG_INFO]
OPTIONS:
-c VM backup list
-l File ot output logging
-d Dryrun/Debug Info [1|2]
(e.g.)
Output will go to stdout
./ghettoVCB-restore.sh -c vms_to_restore
Output will log to /tmp/ghettoVCB-restore.log
./ghettoVCB-restore.sh -c vms_to_restore -l /tmp/ghettoVCB-restore.log
Dryrun/Debug Info (dryrun only)
./ghettoVCB-restore.sh -c vms_to_restore -d 1
./ghettoVCB-restore.sh -c vms_to_restore -d 2
Standard input for script is a file that contains:
1) Full path to the backed up VM 2) Full restore path 3) Restoration disk format 4) Restored VM Display Name (NEW!)
Reminder: When creating this file on a non-Linux/UNIX system, one may introduce ^M characters that will cause the script to misbehave. To ensure that this does not occur, please create the file on the ESX/ESXi host.
Here is a sample of what the file should look like:
[root@himalaya ~]# cat vms_to_restore
#"<DIRECTORY or .TGZ>;<DATASTORE_TO_RESTORE_TO>;<DISK_FORMAT_TO_RESTORE>;<OPTIONAL_RESTORED_VM_DISPLAY_NAME>"
# DISK_FORMATS
# 1 = zeroedthick
# 2 = 2gbsparse
# 3 = thin
# 4 = eagerzeroedthick
# e.g.
# "/vmfs/volumes/dlgCore-NFS-bigboi.VM-Backups/WILLIAM_BACKUPS/VCAP/VCAP-2009-08-18--1;/vmfs/volumes/himalaya-local-SATA.RE4-GP:Storage;1"
"/vmfs/volumes/mini-local-datastore-2/backups/VCSA-5.1/VCSA-5.1-2012-12-25_01-30-36;/vmfs/volumes/mini-local-datastore-1;3"
"/vmfs/volumes/mini-local-datastore-2/backups/VCSA-5.1/VCSA-5.1-2012-12-25_01-30-36;/vmfs/volumes/mini-local-datastore-1;1;VCSA-RESTORE"
Comments in the input file is acceptable so long as the intended line is preceded by a #.
The above sample VM restore file, vms_to_restore, describes the following backup: | VM to restore | Datastore to restore to | VMDK format | Restore VM Name |
---|---|---|---|---|
/vmfs/volumes/mini-local-datastore-2/backups/VCSA-5.1/VCSA-5.1-2012-12-25_01-30-36 | /vmfs/volumes/mini-local-datastore-1 | thin | VCSA-5.1 | |
