+Froxlorbackup
+=============
+
+Backup your Froxlor Webhosting (or anything else) to another server. Encrypted, via ssh.
+
+Works for all versions.
+
+0. install duplicity and all required packages
+1. copy the script to the froxlorserver and run it as `/$PATH/backup-server.sh full`
+2. Add a cronjob like `17 2 * * * /$PATH/backup-server.sh`
+3. Let the magic happen
+
+You can restore your data with
+`duplicity -t nD --file-to-restore relative/neddedFile $EXTERNALPATH/TO//media/mount/duplicity/ /where/to/save/now`
+
+| Parameter | Description|
+| ------------- | ------------- |
+| `-t nD` | The version from how much days in the past should be recovered? |
+| `relative/neddedFile` | Where, relative from the next parameter is the file in the backup? |
+| `$EXTERNALPATH/TO//media/mount/duplicity/` | Where are the duplicity-files stored on the external storage? |
+| `/where/to/save/now` | Where should the recovered file saved to (must not exist)? |
+
+Example:
+`duplicity -t 8D --file-to-restore apache2/sites-available/site.conf ssh://backup@hostname2.domain.tld//home/hostname1/etc /home/user/site.conf`
+
+If you execute this on the machine where you want to restore an eight days old `/etc/apache2/sites-available/site.conf` from the external machine `hostname2.domain.tld`, then the recovered file will be saved in `/home/user/site.conf`
