db backup issues

I've been trying to backup OpManager 8 so it could be set up on a new server, but when attempting to run the db backup script, I get a series of warnings and java errors. Here's a copy of the output:

C:\Program Files\AdventNet\ME\OpManager\bin\backup>backupdb.bat

It just hangs at the end of this, never going back to the command prompt or anything. I've tried running the DB Repair script, which completed successfully, but the backup script didn't perform differently.

Is there any other way to create a clean backup of all the servers and settings within OpManager? If not and this is the only way, I'd appreciate any advice that could help resolve this issue. Thanks.
