OK, that sounds like your jobs are just overrunning, and the backup window
is closing before at least one job can get resources to run. The next
day, under NetBackup's rules for assessing which job to run, that job will
get started first because it has the longest "time since last run".
You also said:
<<aslo I found one drive down ,>>
That is likely enough to make the backups overrun, as all the backups are
trying to use the one drive. If you 'UP' the drive and it stays up well
and good, your problem may be solved.
As you said that you reinstalled the OS as Windows Server 2003, it is
possible that you have lost some important setting.
Check first of all that you have the SIZE_DATA_BUFFERS and
NUMBER_DATA_BUFFERS set as they were before. If the server is backing up
other clients, make sure NET_BUFFER_SZ is set.
Depending on your type of tape drive, there may have been configuration
settings on the old server that affected performance. These would tend to
be in the driver configuration, which for fibre-channel attached drives
depends on the HBA vendor. You may also need to look at the setting of
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\{something}
\Parameters\Device - where {something} is specific to your SCSI interface
type. Newer drivers I think don't have the limitations of the sglist. I
think this is less likely as if it was to low none of your backups would
work at all.
