## Overview
Some usefull scripts for admin or users.
## Scripts
### Proxmox
#### vzdump-hook-lxc-template.pl
This script must be used as a vzdump's hook (the backup utility for CT and VMs for Proxmox).
1. The script will:
* Remove the templates oldest than 2 days (by default).
* Copy the current dump as a template in **/mnt/zfsbkp/template/cache** (by default).
2. How-to use:
* Define a backup as usual (in the Proxmox's webgui) and prefer to select only one container.
* In command on the hypervisor, open **/etc/pve/vzdump.cron** and edit the line of the new dump to add: **--script /usr/local/bin/vzdump-hook-lxc-template.pl**.
3. Customization:
* If you don't store template in the default path (**/mnt/zfsbkp/template/cache**), please edit the variable **$TEMPLATE_DIR** in the script.
### Grav
#### grav_cron
A daily cron to check if [Grav][grav website] got available updates.
* It need to work from the Grav's root directory.
* If an update is available, it will create a empty file (${GRAV_ROOT}/logs/update), else it will ensure the "update" file is removed.
* If an update is available, it will create a empty file (${GRAV_ROOT}/logs/update), else it will ensure the "update" file is removed.
* Be sure to monitore if **${GRAV_ROOT}/logs/update** exist.
