Slow Windows file server cluster backup performance
Dear community, We are using NetBackup version 9.1.0.1 and were previously backing up two physical HP servers running Windows Server 2008 R2 shared data volumes without any issue. We have then migrated to two virtual nodes running Windows Server 2019 under VMware and backup performance is total chaos. Backing up 2GB of data takes 2 hours! We're using VSS and the NetBackup agent is installed on both virtual nodes, since backing them up using VMware native capabilities is not possible because we're using bus sharing (RDM disks). We have already opened a case with Veritas but the support agent is totally lost in the troubleshooting process. Do you have any ideas as to why this is happening and if we're doing things in the right way? I can share additional configuration data or logs if that helps! Thanks a lot and have a lovely week!
Anyone had luck using the CPF1_POLICY parameter with RMAN?
Here is the scenario that I am attempting. I have an Oracle RAC 11g cluster running on Linux and using NB 7.0 client NB 6.5 Server. I have the same environment duplicated at a remote site. I am backing up my database to Oracle's FRA ("Fast Recovery Area" Disk location in ASM). I then run a backup to tape using RMAN and NB. I would like to use RMAN's duplex capability to write to two different media servers simultaneously. An Oracle document suggested using the CPF{N}_POLICY and CPF{N}_SCHED parameters in the RMAN script. I have tried this. RMAN is making two copies of the backup and I get I can write to both media servers but in most cases the backup copies are being written to the same server rather than the alternate. Here is my RMAN script: run { ALLOCATE CHANNEL s1 DEVICE TYPE SBT PARMS 'ENV=(NB_ORA_SERV=bka-01, NB_ORA_CLIENT=oracle-server, CPF1_POLICY=OraDBDefaultApp, CPF1_SCHED=OracleLevel0)'; ALLOCATE CHANNEL s2 DEVICE TYPE SBT PARMS 'ENV=(NB_ORA_SERV=bka-01, NB_ORA_CLIENT=oracle-server, CPF1_POLICY=OraDBDefaultApp, CPF1_SCHED=OracleLevel0)'; ALLOCATE CHANNEL s3 DEVICE TYPE SBT PARMS 'ENV=(NB_ORA_SERV=bka-01.site2, NB_ORA_CLIENT=oracle-server, CPF2_POLICY=OraDBDefaultApp, CPF2_SCHED=OracleLevel0)'; ALLOCATE CHANNEL s4 DEVICE TYPE SBT PARMS 'ENV=(NB_ORA_SERV=bka-01.site2, NB_ORA_CLIENT=oracle-server, CPF2_POLICY=OraDBDefaultApp, CPF2_SCHED=OracleLevel0)'; BACKUP COPIES 2 BACKUPSET ALL; } Thanks Brian
