# Error restoring collect database

Asked by pmagdon on 2015-11-18

Dear all,
we have difficulties in creating a copy of a collect database on a local machine. Our partner used the function backup to create a backup of the original running collect survey. When I try to import the backup file on my machine using the restore function, it reads the data. However, when the progress bar switches to processing I get the following error: "error restoring data: null". I can see the project then in the survey designer but there seem to be no data entries in the data manager. Any idea what to do or were to start looking for a more detailed error description in the log files?
Can it be related to different versions of openforis? I use 3.8.19 while our counterpart uses 3.6.6??

Greetings
Paul

Dear Paul,  
sorry to hear that you have problems with this feature. Can you provide more details on that? Can you send me the log files in a private email? I need to see the files collect.log and catalina.out that are located in c:\opt\openforis\collect\tomcat\logs.  
Thanks,  
Stefano

Dear Stefano,
thank you for providing another update **(3.8.21)** which finally solved the problem that was related to the plot images included in the backup file.
