Tape_copy_command

Hi,
We are using Netbackup for taking the backup.In the init<sid>.sap we are using tape_copy_command=cpio. Our os is Solaris. Please confirm whether we can take the backup using Netbackup with tape_copy_command=dd.

In theory yes. Nothing indicates that it might not work. If I was you I would do a test run on a sandbox system.
Read the info available in help.sap.com and remember to keep an eye in the recommended parameters.

Backup fails with a CPIO error even though starting with DD

Hi All,
I have started a db backup of a sap system directly onto a tape.
I am using DD since size of each datafile is more than 2 GB.
In a total of 112 data files, 109 got copied but suddenly, the following error came and brbackup got terminated.
This has happened for the second time and that too after using a separate set of tapes.
Can you please provide me your views on it. I am unable to understand why should the error contain "CPIO" if i am using DD.
The parameter settings have been made correctly in the init<SID>.sap file.
Regards,
Hari Kishan

Hello,
in addition to all the backup files, brbackup will always write one more file to the tape, right at the beginning. This file is called .tape.hdr0. It contains, in essence, the name of the tape and date of the current backup. As far as I know this file will always be written by cpio, no matter what your tape_copy_command is. At the end brbackup will check this file again, and that step failed here.
So it seems there is a problem with either your tape or your tape drive.
But don't worry about cpio!
hope this helps

Redirecting autobackup to disk even though data/log-backup went to tape?

I understand. I've run into a netbackup error described in Metalink Note 416150.1 where using a CONTROLFILE AUTOBACKUP to tape with the wrong client settings enabled (DISALLOW_CLIENT_RESTORE and DISALLOW_CLIENT_LIST_RESTORE) would give me an RMAN error.
We're trying to fix this, but as a work-around, I wanted to redirect the autobackup to disk no matter where it goes, tape or disk. Is there a way to configure RMAN as such?
