Resolving common client performance problems

The table contains common client problems and actions that can help to improve client performance.

Scenario Solution More information
During incremental backups, the client gets out of memory errors that cause the operating system to use more virtual memory or use more RAM than the client system can handle. How can I reduce these memory errors and have my backups complete within the backup window? Update the client system hardware by increasing the system memory. If it is not possible to update the hardware, try running journal-based backups. If more memory is needed, try memory-efficient incremental backups. For more information, see the following topics:
Journal-based backups do not complete within the backup window. What alternatives can I use? Try one or more of the following actions:
  • Use image backups to back up an entire volume as a snapshot
  • Examine the design of the file system on AIX®, Linux, and Solaris operating systems
 For information about image backups, see Image backup.

For information about tuning client file spaces, see File space tuning.
How can I reduce the amount of client data that is sent across the network to the IBM Spectrum Protect server? Try one or more of the following methods:
  • Use compression during backup operations
  • Use include-exclude options to exclude files from the backup operation
  • Use client-side deduplication
  • Use LAN-free backups
 For more information, see the following topics:
Some backup-archive clients back up much of the same data daily. How can I prevent the data that is a duplicate of the data from the previous day from being resent to the server? Run incremental backups, use client-side data deduplication, or both. Checklist for data deduplication
We have limited network bandwidth. How can I improve the communication between the client and IBM Spectrum Protect server? Fine-tune the network and communication settings. Tuning network performance
What other methods can I use to reduce the time that it takes to back up a client? Try one of the following actions:
  • Use multiple client sessions for backup operations
  • Set the resourceutilization option to optimize the number of multiple sessions
