To automatically create a sparsbundle file used for Time-Machine Backups on Network Attached Storages you can use the following script.

#!/bin/bash

NAME=“$(system_profiler | sed -ne \
’s/.*Computer Name: //p‘)_$(ifconfig en0 | awk \
‚$1==“ether“{gsub(„:“,““);print$NF}‘).sparsebundle“

echo „Creating $NAME…“

hdiutil create -size 100g -fs HFS+J -volname „Time-Machine Backup“ „$NAME“

echo „Done.“

THis is based on the hints provided in c’t magazine 12/2010 (p. 174)
