I am currently doing a survey of online database techniques in use by major database management systems. Can anyone tell me what facilities INFORMIX has for making a backup of a database while updates are still being applied to the database and what technique does it use to do this ? Does the online backup require transaction quiescence ? Does it require update quiescence ? What sort of degradation of the transaction throughput can be expected for the time during the backup when the transactions are not quiesced ? Any information on this topic would be greatly appreciated. Ted Heaven e-mail: heaven@bnr.ca Bell Norther Research phone: (613) 765-4650 Ottawa, Canada
