Timeouts properties in the NetBackup Administration Console

The Timeouts properties apply to selected master servers, media servers, and clients.

Figure: Timeouts dialog box

Timeouts dialog box

The Timeouts dialog box contains the following properties.

Table: Timeouts dialog box properties

Property

Description

Client connect timeout

Specifies the number of seconds the server waits before it times out when it connects to a client. The default is 300 seconds.

Backup start notify timeout

Specifies the number of seconds the server waits for the bpstart_notify script on a client to complete. The default is 300 seconds.

Note:

If using the bpstart_notify script: The Client read timeout (CLIENT_READ_TIMEOUT option) must be equal to or greater than the Backup start notify timeout (BPSTART_TIMEOUT option). If the Client read timeout is less than the Backup start notify timeout, the job can timeout while the bpstart_notify script is running.

File browse timeout

Specifies how long the client can wait for a response from the NetBackup master server while it lists files.

Note:

If it exists, the value in a UNIX client's $HOME/bp.conf file takes precedence to the property here.

If the limit is exceeded, the user receives a socket read failed error. The timeout can be exceeded even while the server processes the request.

Use OS dependent timeouts

Specifies that the client waits for the timeout period as determined by the operating system when it lists files, as follows:

  • Windows client: 300 seconds

  • UNIX client: 1800 seconds

Media mount timeout

Specifies how long NetBackup waits for the requested media to be mounted, positioned, and ready on backups, restores, and duplications.

This property applies to currently selected master servers.

Use this timeout to eliminate excessive waiting time during manual media mounts. (For example, when robotic media is out of the robot or is off-site.)

Client read timeout

Specifies the number of seconds to use for the client-read timeout. This timeout can apply to a NetBackup master, remote media server, or database-extension client (such as NetBackup for Oracle). The default is 300 seconds.

If the server does not get a response from a client within the Client read timeout period, the backup or restore operation, for example, fails.

The client-read timeout on a database-extension client is a special case. Clients can initially require more time to get ready than other clients. More time is required because database backup utilities frequently start several backup jobs at the same time, slowing the central processing unit.

Note:

For database-extension clients, Symantec suggests that the Client read timeout be set to a value greater than 5 minutes. 15 minutes are adequate for many installations. For other clients, change this property only if the client encounters problems.

The sequence on a database-extension client is as follows:

  • NetBackup on the database-extension client reads the client's client-read timeout to find the initial value. If the option is not set, the standard 5-minute default is used.

  • When the database-extension API receives the server's value, it uses it as the client-read timeout.

See Client Settings properties for UNIX clients in the NetBackup Administration Console

Note:

If using the bpstart_notify script: The Client read timeout (CLIENT_READ_TIMEOUT option) must be equal to or greater than the Backup start notify timeout (BPSTART_TIMEOUT option). If the Client read timeout is less than the Backup start notify timeout, the job can timeout while the bpstart_notify script is running.

Backup end notify timeout

Specifies the number of seconds that the server waits for the bpend_notify script on a client to complete. The default is 300 seconds.

Note:

If this timeout is changed, verify that Client read timeout is set to the same or higher value.

Media server connect timeout

Specifies the number of seconds that the master server waits before it times out when it connects to a remote media server. The default is 30 seconds.
