Hi, I've successfully built ubik_cp, copied together with libafshcrypto and librokenafs to the box I intend to do the backups and it has successfully backed up both prdb and vldb databases. One question remains, what is the role of prdb.DBSYS1 and vldb.DBSYS1 files in the same directory as prdb.DB0 and vldb.DB0? Thank you! Cheers Geza Gemes
