 The script makes snapshot of a VM, copies the "old" vmdk and other files
 to a backup location, then deletes the snapshot.<br>
 This approach, where backup in time is full backup takes up a lot of space.

 ### Install

+* [Download](https://github.com/lamw/ghettoVCB/archive/refs/heads/master.zip)
+  the repo files on a pc from which you would upload them on to esxi
+* create a directory on a datastore where the script and configs will reside<br>
+  `/vmfs/volumes/6187f7e1-c584077c-d7f6-3c4937073090/ghetto`
+* upload the files, should be 6, can skip `build` directory and `readme.md`
 * ssh in to esxi
-* `cd /tmp`
-* `esxcli network firewall ruleset set -e true -r httpClient`
-* `wget https://github.com/lamw/ghettoVCB/releases/download/2021_10_20/vghetto-ghettoVCB.vib --no-check-certificate`
-* `esxcli software vib install -v /tmp/vghetto-ghettoVCB.vib -f`
-* check `ls /opt`
+* cd in to the datastore ghetto directory
+* make all the shell files executable<br>
+  `chmod +x ./*.sh`

 ### Config and preparation

 Gotta know basics how to edit files with ancient `vi`

-* Config file template is in `/opt/ghettovcb/ghettoVCB.conf`<br>
-  Make copy of it<br>
-  `cp /opt/ghettovcb/ghettoVCB.conf /opt/ghettovcb/ghetto_1.conf`<br>
+* cd in to the datastore ghetto directory
+  `cp ./ghettoVCB.conf ./ghetto_1.conf`<br>
 * Only edit this file, for starter setting where to copy backups<br>
  `vi /opt/ghettovcb/ghetto_1.conf`<br>
  `VM_BACKUP_VOLUME=/vmfs/volumes/6187f7e1-c584077c-d7f6-3c4937073090/Backups`
 * Create a file that will contain list of VMs to backup<br>
-  `touch /opt/ghettovcb/vms_to_backup_list`<br>
-  `vi /opt/ghettovcb/vms_to_backup_list`<br>
+  `touch ./vms_to_backup_list`<br>
+  `vi ./vms_to_backup_list`<br>
  ```
  OPNsense
  Arch-Docker-Host
  ```
 * Create a shell script that starts ghetto script using this config for listed VMs<br>
-  `touch /opt/ghettovcb/bin/ghetto_run.sh`<br>
-  `vi /opt/ghettovcb/bin/ghetto_run.sh`<br>
+  `touch ./ghetto_run.sh`<br>
+  `vi ./ghetto_run.sh`<br>
  ```
  #!/bin/sh

+      -f $GHETTO_DIR/vms_to_backup_list \
      &> /dev/null
  ```
  Make the script executable<br>
-  `chmod +x /opt/ghettovcb/bin/ghetto_run.sh`
+  `chmod +x ./ghetto_run.sh`
 * for my use case where TrueNAS VM cant be snapshoted while running because
  of a passthrough pcie HBA card there needs to be another config
 * Make new config copy<br>
-  `cp /opt/ghettovcb/ghetto_1.conf /opt/ghettovcb/ghetto_2.conf`
+  `cp ./ghetto_1.conf ./ghetto_2.conf`
 * Edit the config, setting it to shut down VMs before backup.<br>
-  `vi /opt/ghettovcb/ghetto_2.conf`<br>
+  `vi ./ghetto_2.conf`<br>
  `POWER_VM_DOWN_BEFORE_BACKUP=1`
 * edit the run script, add another execution for specific VM using ghetto_2.conf<br>
-  `vi /opt/ghettovcb/bin/ghetto_run.sh`<br>
+  `vi ./ghetto_run.sh`<br>
  ```
  #!/bin/sh
