Timeouts properties
The Timeouts properties apply to selected master servers, media servers, and clients.
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. 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. 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: |
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 that NetBackup waits for a response from a client before the operation attempt fails. 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 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.
It is recommended to increase the timeout value in the following situations: 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. A setting of 15 minutes is adequate for many installations. Backing up directly to a Cloud Catalyst storage server. If the value is not increased for both the master server and the media server, you may see jobs failing with the following message in the job details: Error bpbrm (pid=119850) socket read failed: errno = 62 - Timer expired Note that increasing the timeout is not needed it you use a storage lifecycle policy to first back up to an MSDP storage server and then duplicate the data to an MSDP cloud storage server
using an optimized duplication operation. (This is the recommended method
of operation.)
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. 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. |
