Hi Mark, Thank for the explanation.
What about restoring (GBAK) both databases at a particular moment then they should be even "physically" identical at that moment? At this moment it's level 0. But then you have tell the source db where level 1 starts. Maybe by inserting something in RDB$BACKUP_HISTORY? My strategy is to never repeat level 0 and increment level every third day. Have done this for a while and it seems to work. Thx,
