Re: Using RMAN

[Nikunj Gupta]

Hi, I am not sure... what your exactly plan to do... But, You can configure RMAN to backup on DISK and use some TAPE MANAGEMENT UTILITY or SYSTEM UTILITY (If it is there) to backup from your DISK. Also that utility can delete after successful backup from DISK to TAPE depending on configuration and requirement.   Now, in case of RESTORE... RMAN will try and restore from DISK, but if that is not there then you can restore back from TAPE to DISK and use RMAN to recover.   Sounds logical ??   With all this in place.. also plan for backup of RMAN Repository.   Can you please update me on the methodology you adopt.   Have fun..   Nikunj   PS: This is just to give an idea... you may have to workout some extra steps... and perform a test before implementing in REAL WORLD.           ------------------------------------ Make a FREE long distance call from your PC! http://www.eboom.com/free/ ----- Original Message ----- From: Sona To: Multiple recipients of list ORACLE-L Sent: Wednesday, January 16, 2002 03:20 PM Subject: Using RMAN Hi Currently we are using Unix scripts to do backups.We keep last 2 days of backups on the disk and also take the backups on tape daily. We are planning to use RMAN for backups and would like to maintain the the same policy of 2 days backup on disk and daily tape backups. Is it possible to implement this using RMAN? Which backup will RMAN remember (while restore) the disk backup or the tape backup? If we try to use the incremental strategy ,then how would RMAN remember the last incremental level 0 backup ? It will not be present on disk since we only keep the last 2 days backup on it. How do i use RMAN to do restore/recovery in this case? I heard that taking backups on tape is faster than on disk when using RMAN? Is it true?   Could RMAN users share their backup/recovery  strategies ,please.   TIA
