10_Backup.md

## Typical Usage

This is the main script to start a backup. The script *backup.sh* is the one to add as a cronjob. It will start

* the dumps of local databases
* the file transfer to an external repository

Both of these steps can be started seperately (see next pages).

## Typical Usage

* on Linux: as a non root user use sudo `sudo ./backup.sh`
* on MS Windows: start it as user `./backup.sh`. Or double click it in a file manager (e.g. Explorer). The first time it asks what program should be used to open *.sh files - select the bash.exe ornavigate to it.
