Use Ghostscript to compress a PDF

I also learned that I can use the gs command to accomplish everything in one go:

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dBATCH -dColorImageResolution=150 -sOutputFile=output.pdf someBigFile.pdf

# Server in Backup aufnehmen

Jedes Backup hat ein eigenes LVM mit einem Mountpunkt unter
`/mnt/backup/{server}`

* Mit `vgdisplay` freien Speicherplatz prüfen (Punkt `Free  PE / Size`)
* Mountpunkt erstellen mit `mkdir /mnt/backup/{server}`
* Mit `lvcreate -L 100G -n {server} VG01_srsouthp08` ein neues logical
volume erstellen (die 100G sollten je nach System angepasst werden)
* Mit `mkfs.ext4 /dev/VG01_srsouthp08/{server}` neues Volume formatieren
* Mit `mount /dev/VG01_srsouthp08/{server} /mnt/backup/{server}` das
Volume mounten
* Einen entsprechenden Eintrag in der `fstab` vornehmen:
`/dev/mapper/VG01_srsouthp08-{server}   /mnt/backup/{server}    ext4
defaults,_netdev        0       0`
* Den Ordner `/mnt/backup/{server}/dirvish` erstellen und darin die
`default.conf` anlegen.
* In der Datei `/etc/dirvish/backup-dirvish.conf` ganz Unten den Server
in die Variable `VAULTS` eintragen
* In der Datei `/etc/cron.d/adfinis-dirvish-backup` einen Cronjob für
den Server erstellen
* Erstes Backup mit `dirvish --vault {server} --init` erstellen.
Achtung!: Dies kann mehrere Stunden dauern und sollte deswegen in einem
`screen` laufen.

On Client add key, exclude hughe archives and make sure the database is in a state where the backup can be used or it has a dump from it.
Test with dirvish --no-run --vault {server}
