+```
+# Usage
+## File Structure on your system
+```
+/ - Root of your filesystem
+├── var - stuff to backup (example)
+└── etc - configuration directory
+    ├── tubs.sh - Backup Script
+    └── tubs.config - Example configuration
+```
+1. Create a folder in /etc with the name "tubs"
+2. In there(/etc/tubs/) you have to copy the [scirpt](./tubs.sh)
+3. Now create an [configuration file named "tubs.config"](./tubs.config) in this directory you can see an example in this repo. If the path of this file is not exactly /etc/tubs/tubs.config, then you need to adjust this in the [script](./tubs.sh) on Line 16 (CONFIG_FILE="path/to/file")
+
+## Execution
+1. Run the script with the "init" argument to create the directory structure in the destination
+```
+    /etc/tubs/tubs.sh init
+```
+2. Run the script with the "backup" argument to run the backup job
+```
+    /etc/tubs/tubs.sh backup
+```
+You will get colorful output if something does not work.
+
+## Cron Job
+
+Create an cron job to run this script every day (or whenever you want)
+```
+crontab -e						       # to edit (then 'i': insert, ':wq!': save and quit)
+10 * * * * /etc/tubs/tubs.sh backup    # every hour at 10"
+0 */4 * * * /etc/tubs/tubs.sh backup   # every 4 hours at 0"
+0 9-17 * * * /etc/tubs/tubs.sh backup  # every hour at 0" between 9 and 17
+0 2 * * * /etc/tubs/tubs.sh backup     # daily at 2am
+0 0 * * MON /etc/tubs/tubs.sh backup   # every Monday at 0am
+0 0 * * 1-5 /etc/tubs/tubs.sh backup   # daily from Monday to Friday at 0am
+0 0 * * 0 /etc/tubs/tubs.sh backup     # weekly on Sunday
+0 0 1 * * /etc/tubs/tubs.sh backup     # monthly (1rst day at 0am)
+0 0 1 */3 * /etc/tubs/tubs.sh backup   # every quarter (1rst day at 0am)
+0 0 1 1 * /etc/tubs/tubs.sh backup     # yearly (01/01)
