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.

 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.

Hello Joe  

Just schedule another backup of the archive logs 1 hour (or 5 minutes) after
the regular backup. NetBackup will take a second (complete) backup of the
archive file and when you want to restore , restore the last copy of the
files.

RESEND: never saw it get posted:  

Can we force veritas netbackup (HPUX) to NOT backup open files?  

Here is the problem: while arch process is writing out archive logs, the
netbackup script that backs up the arch directory will write a partially
written log to tape, we're trying to avoid that.  

is our only alternative determine(out of data dictionary) how many log groups we have and assuming 3, that if we take the max log seq# minus the
numebr of groups we have, gives us the oldest log that we can be sure is
complete?  

ie: current log is 543, we have 3 log groups, 543-3 = 540, since oracle
wouldnt start overwriting # 540 until it was successfully archived, that we
can back up, up thru log seq# 540 and can be sure # 540 is complete?  

thanks, joe
