The following items are performance and troubleshooting best practices:

• Use the performance-tuning documents available on the NetBackup support Web page.

• Use only a dedicated server for the NetBackup primary server. Do not use a server that hosts other applications or one that stores data. Plan periodic maintenance for all of the backup servers.

• Consult the Troubleshooter in the NetBackup Administration Console or the NetBackup Status Codes Reference Guide for all error conditions:

• Always install the latest NetBackup release updates that are available from Veritas.

• Verify all SCSI-related operating system configuration files (such as the Solaris st.conf file), when you install system release updates.

• For problems with devices, consult the vendor for firmware upgrades and consult the NetBackup hardware compatibility list for supported firmware levels.

• Do not use the NetBackup DISABLE_RESOURCES_BUSY touch file.

• Do not disable the operating system TCP_NODELAY functionality.
