We are seeing some strange behavior with NetBackup 3.42 (NDMP) ONTAP 6.2R1 ( and 6.1R1) and StorakeTek 9840 ( A and B) drive We run a benchmark backup on the 150GB volume and it took about 4 hours ( during which there was a continuos flow of data to the tape) Now that we scheduled a daily backup of the nightly.0 snap shot we are seeing some strange behavior. After backing up 30-60% of the data, NDMP session becomes Halted, no data is written to tape, and nothing is going on. It remains in this state for hours and then the backup is resumed. And the whole backup job can take 14-18 hours ( where it used to take 4hr) CPU utilization on Filer is at average of 4-8% ( OS is 6.2R1 and 6.1R1 on the other) Please help in explaining this behavior. We are seeing this on more then one files TIA Ilya --------------------------------------------------------------------------- This message (including any attachments) is confidential and may be privileged.
