Michael, Here is another perspective: You'll know you need incremental backups when your backup administrator tells you. :-) Everything here depends on your specific situation: - How large is your database? - What is the update cycle? - i.e. is every day the same, or is it a weekly cycle, etc. - How many archive logs are produced? - What are the recovery requirements? What is an acceptable downtime? - What is the speed and capacity of your backup hardware? My feeling is that you need to get the answer to these questions (i.e. the requirements) before you can begin crafting a solution. I don't think you can just pick a database size and say past that point you need to switch to incremental backups. Dennis Williams
