database problem ?

Hello,

I have some questions  about dataprotector database

The first is that the DB  seems to have an important size ( 22GO) , it's normal ?

Then , the DB is located in 2 differents places:

C:\users\All users\OmniBack\server\db80\dcbf

C:\ProgramData\OmniBack\server\db80\dbcf

It's normal ??

I'm on dataprotector 8 and on windws 2012 server

Tanks
