RE: Backup Strategy

Users can't afford to be without the database to work, that is for sure.

I know that there are a lot of recovery scenarios, and plans for them... But I was talking about backups... how many, what type of backups, etc.

So far I've been doing ok with daily exports and weekly full backups, just wanted to hear if there is anything else I should be doing,

Veronica,

Before you can decide on what your backup strategy will be, you really need to talk to the users of your database.

One of the most important pieces of information to get from your users is the "Mean Time to Recovery". Simply put, you ask the user how long they can afford to be without a database.

If they tell you "no more than 10 minutes", then you had better devise and implement an automatic fail-over (either hot-standby, or if you can share the disks, automatic fail-over).

If they tell you "no longer than 1 hour", then you had better make sure that your backup and recovery plan can restore the data files and recover the database within the time frame.

There are probably a dozen different scenarious that you need to consider. Each one will lead to to different types of recovery scenarious. Each one will have a different cost (both in dollars and your time).

hope this helps.

Hi listers,
I was wondering how do you decide your backup strategy.....

I do daily full exports and weekly full backups with database in archivelog mode.
Plus weekly Operating System Backup.

Is this all I can do to ensure fast recovery of the database or server when it is needed?

Any input on this topic will be appreciated!
