You can optimize the performance
of Tivoli® Storage
Manager clients.
Review the methods for backing up data and select the best methods
for your environment. Review the information about client options
and adjust configuration settings accordingly.
Selecting the optimal client backup method
You can use several techniques with the backup-archive
client to help you ensure the best performance during various types
of backup processing.
Common client performance problems
Typical client performance issues are often related to
backup operations that do not complete within the backup window or
that send too much data over the network.
Client restart options
The commrestartduration and commrestartinterval options
affect how aggressively the client attempts to reconnect with the
server if a network outage or other condition interrupts client and
server communications.
Tuning memory
You can tune the client to use less memory during incremental
backup operations.
Tuning client data throughput
Use client options to improve the throughput of client
data to the IBM® Tivoli Storage Manager.
Tuning journal-based backups
To help improve the performance of incremental backups,
you can run journal-based backups.
Optimizing restore operations for clients
Standard IBM Tivoli Storage Manager progressive
incremental backup operations are optimized to restore individual
files or small numbers of files.
File space tuning
Using Tivoli Storage
Manager virtual
mount points can enhance the performance of backup and restore operations
on file systems that contain millions of files.
Windows system state backups
The most recently released versions of the Tivoli Storage
Manager backup-archive
client and Tivoli Storage
Manager server
software include updates that improve the performance of Windows system state backup and restore operations.
Performance tuning for LAN-free environments
LAN-free backup can improve performance because the backup
traffic can be routed over the SAN instead of the LAN. LAN-free data
movement can make LAN bandwidth available for other uses and decrease
the load on the Tivoli Storage
Manager server,
allowing it to support a greater number of concurrent client connections.
