ontape -s level 1 fails

Hi, I have made backups of level 0 with ontape -s and then select the 0 option. Now i want to make level 1 backups. But it fails because it says: "no level 0 backup made", but i did this already... Does anyone know how ontape "remembers" so that i can make level 1 backups again? This problem started after a informix update... (not by me!) Thanks, Marc Groeneveld.

Versions prior to 7.30 maintained a single record in the reserved pages that recorded the last level 0 date and time, and the same for level 1 & level 2 if they are later than the higher level. IDS 7.3x+ maintains a more extensive history. You can access the older versions archive history in onmonitor and the newer ones using onstat -g arc. > This problem started after a informix update... (not by me!) An update AFTER the last level zero? When you upgrade the history records are wiped as the engine assumes that the archives you have from before are useless except to restore the the prior version in an emergency. You MUST take a level 0 ASAP after an upgrade. Art S. Kagel
