Thanks for your help!

But i find a solution that works... 
At the server runs a cronjob every minute. The cronjob looks in a directory if there is an file "vaultname". This file is the default.conf for the given vault with the current ip-address inside. So the cronjob runs dirvish (as root) with this config. The directory is writeable for each laptop user. If now someone will start a backup he can local run a script which build and transfers the vaultfile to the server and within a minute the dirvish runs.
