Hi All.
I am doing a file system backup of the EMC BCV disks mounted in the
Netbackup Master/Media server.
It is a direct backup.   That is, the Fiber Channel disks from the EMC
are connected to the Netbackup Master/Media server and there is a SCSI
connection to the Robot.
I do a full Oracle backup everyday of about 68GB's.  Usually the backups
take about 2 - 21/2 hours.
Occasionally about once or twice a week, they run longer and take about
6 to 7 hours. =20
But now in the last two days, the same backup is taking 7 to 8 Hours.
I have seen the bptm and other logs and looked for any errors or
SIZE_DATA_BUFFERS full type of messages and did not find any. =20
There is no LAN/Network involvement in here ...so it is pretty straight
forward.
The Netbackup Master/Media Server is running on Solaris 7 with GigE.
The Robot is a STK L180.
Netbackup Version running is 3.4.1.
I searched through the mailing list archives...but no luck for this
scenario.
Any suggestions on this?
I really appreciate the response.
Thanks.
