Thank you very much for your answer Dmitry. However my first question remains: why after a cycle backup/restore the Next Transaction was 304 and not 3?
My understanding so far is that after a cycle backup/restore the ID of all transactions in the backup is put in 1. So, the Next Transaction would be 3 or a number very close to 3. Why it was 304?
