Not sure what EXT3 is, but I understand how the archive bit works - that was
not the actual issue - issue I wanted to clarify is whether NBU would treat
2 policies differently for the same client.  :-)
 
Thanks

The archive bit which the full and differential backups clear is a facility
of the file system.  Whether you are running NTFS or EXT3 the archive bit is
kept per file at the file system level.  It doesn't matter WHAT backup
software you use to clear the archive bit, incremental backups will only
backup files with the archive bit set and fulls will backup EVERYTHING.  The
only difference is that full and differential backup RESET the archive bit
if it is set.  Essentially, anytime you change a file (open it, save it) the
archive bit gets set to "1" or "please back me up."  When a full or
differential backup comes along it backs up the file and clears the archive
bit.  This really has nothing to do with Netbackup or policies.  You can run
simple backups via windows backup and it still uses the same archive bit.
At one point I was using WinZip to clear archive bits and rub remote backups
while a tape library was down.

Subject: [Veritas-bu] Clarification - Policies


All
I just wanted clarification on this, to be 100% sure I understand what is
happening.
 
NBU 5.1 MP2 Win2k3 + 2 SAN Media Servers + thousands of clients
 
Scenario: Have a Policy that does Incr & Full for CLIENT1 - Policy is called
"Backup_Client1"
I have have a 2nd Policy, that is deactivated called "Manual_Backup_Client1"
 
now, lets assume the full backup for Client1 failed. If I turn on the
Manual_Backup_Client1 policy, it performs and completes the backup without
any problems.
 
But am I right in thinking the archive bit would be set correctly, so that
when the Policy "Backup_Client1" runs, it is "aware" a full backup was
completed successfully?
 
My thinking is, the policy WONT have a clue, as the Policy that performed
the backup is different, and therefore may not share this info!
 
Clarification?
 
Thanks
