Home -> Community -> Mailing Lists -> Oracle-L -> RE: Backup Strategy - Informal Survey
Robert
I don't think a full export has a place since your largest tables are probably too large to reimport in a reasonable amount of time. I like Jay's suggestion though. But your original question wasn't about a full export, you just said export. My answer is a definite "yes". Following Pareto's rule (80/20), of the hundreds of tables, most will be relatively small, where import would be feasible. I find that developers often need to tinker with small codes tables, for example. Since they don't want to write a screen for an infrequent task, there is a higher-than-average chance they will bollix the table. Being able to quickly produce a week-old copy of the table can be a real butt-saver. And a heck of a lot easier to do from an export than a TSPITR. I also try to impress on the developers that before they monkey with a table to ask me to do a special export, and that gives me the chance to innocently ask what they are up to.
Previously I did exports of large tables because that checked each block,
but with RMAN, that is not necessary.

I'd like to pose a question to you all and get your response. If you are running a database that is larger than 250GB, what place in your backup strategy does a logical export have? Do you do logical exports at all, and if so with what frequency? Do you feel that logical exports are an important part of your backup/recovery strategy?
