FW: kinda OT: veritas netbackup
Hi, I am the other guy involved in this issue of Not backing up OPEN files on Unix with Netbackup. We are keeping 2 days of logs on disk up to 60gig of logs.. The tape backup people are not happy about us backing this up often to provide extra redundancy especially as we implement this for every oracle system we have. Yes, we have considered running other backups but we really wanted to see if Veritas could close this logic hole for us because we have a directive to keep our solution simple and secure. I know on windows its no problem and veritas squawks when the files are in use... Anyone know if the "only BACKUP close files" feature exists in Unix.

Yes, we have coded it to do thisand it works but for many reasons.. including simplicitywe want to avoid thissolution for theentire12B enterprise solution... when it confuses others, and is much more vulnerable for screwups with Mount point management and recovery.

Do not back it up. -Original Message-From: JOE TESTA [mailto:[EMAIL PROTECTED]]Sent: Thursday, December 19, 2002 9:50 AMTo: Multiple recipients of list ORACLE-LSubject: kinda OT: veritas netbackup RESEND: never saw it get posted: Can we force veritas netbackup (HPUX) to NOT backup open files?

Re: FW: kinda OT: veritas netbackup
Holiday Greetings, We use NetBackup Exec on a Novell network and the backup manual say's that it can backup open files and not hamper the operation of the system. Horse pucky. When a file is open by Oracle the tape backup backs up the file without a lock but if Oracle needs to use the file for read/write it finds the file in use by another and places the file in an offline mode and requires recovery to bring it back into the sanity mode. According to oracle no backup program other than their own should be used. There is no support guarantee from Oracle if the backup is taken when the database is open. St. Bernard software disagrees but I still only trust the Oracle solutions. Cold backups or hot backups or RMAN backups only.

From an external perspective this is easy to say but... a) You've coughed up a whole lot of cash for NetBackup. b) You're looking for a good enterprise wide solution Seems like its time to go RMAN hth connor --- Spears, Brian [EMAIL PROTECTED] wrote: Hi, I am the other guy involved in this issue of Not backing up OPEN files on Unix with Netbackup.
