Hi, All:
We have a new system installed Oracle 8.1.6. Now we are considering the method of Backup/Recovery.
In our system 2 disks and 1 tape device can be used for backup. And I think there are 2 ways to use them:
1). 1 disk : archive log;
1 disk : backup using by RMAN;
1 tape : backup's backup
2). 1 disk : archive log;
1 disk : the copy of the archive log;
1 tape : backup using by RMAN;
I don't know which is better? which is common?(The data size is about 20GB)
Can some one give me some advices?
Thanks.
