(Ubuntu 14.04.3 LTS) Youtrack data loss

Hello youtrack Team,

we are using the hosted .jar version of youtrack on ubuntu 14.04.3 LTS. so yesterday i´ve started to work with youtrack, configured the smtp server, created projects´n tickets but i accidentally closed the process by closing my terminal window.

today i´ve started the youtrack.jar again with:

java -Xmx1g -jar /usr/local/youtrack/youtrack-6.5.16713.jar 8080

Problem: 

he redirects me to the configuration page, /rootGo. So i killed the process and searched for the teamsysdata folder where youtrack stores the data. Find gives me two directories...

find -name "teamsysdata"

./home/youtrack/teamsysdata
./teamsysdata

How can i restore the data? Im only working as root, i can't say why there is a youtrack-home folder inside ./home. How can i change the youtrack home directory?

Thanks Stephan
