Communication parameters (Windows)
 
Parameter
Description
CommunicationMethodDSS
Low-level communication method between DS-Client and DS-System.
2 = Network packets encrypted on top of existing data encryption. Slowest method. (Default)
1 = Same as method 0 with a different implementation for troubleshooting purposes only.
0 = Network packets not encrypted. Fastest method.
CommunicationMethodMLR
Low-level communication method between DS-Client and DS-MLR / DS-Recovery Tools.
2 = Network packets encrypted on top of existing data encryption. Slowest method. (Default)
1 = Same as method 0 with a different implementation for troubleshooting purposes only.
0 = Network packets not encrypted. Fastest method.
DSSystemAlternatePort
Alternate port to connect to DS-System if the DS-Client fails to connect on the default port (4401).
Default: 0
Note: A value of 0 means there is no alternate port.
HessianAPIListenIP
IP address the DS-Client uses to listen for Hessian API connections. Use 0.0.0.0 to listen on all interfaces.
Note: This parameter requires the DS-Client to restart before taking effect.
HessianAPIListenPort
Port on which DS-Client listens for Hessian API connections.
Default: 4411
Note: This parameter requires the DS-Client to restart before taking effect.
HessianAPILogFile
File where the Hessian API server writes log messages and events. You can use any valid file name.
Note: This parameter requires the DS-Client to restart before taking effect.
HessianApiLogLevel
Level of logging to write to the Hessian API server log file.
warning (Default)
debug
info
error
fatal
Note: This parameter requires the DS-Client to restart before taking effect.
HessianApiSSLFile
SSL certificate/key file to use for the Hessian API server. This should be in PEM format.
Default: C:\Program Files\CloudBackup\DS-Client\api.pem
Note: This parameter requires the DS-Client to restart before taking effect.
HessianApiSSLPassword
Password for the SSL certificate/key file.specified in the HessianApiSSLFile parameter.
Note: This parameter requires the DS-Client to restart before taking effect.
LaptopCheckInterval
Interval at which DS-Client checks the network connection for schedules configured with the DS-Client on portable computer (verify network connection) option.
MaxQueuedMessages
Maximum number of queued messages during communication with DS-System.
Default: 128
Range: 1-2048
MaxSendSize
Maximum TCP/IP socket block size to send at one time. Larger values can be used when communication over a fast connection is not performing as expected.
Default: 1500
Range: 0-104,857,600
Note: Do not specify a value smaller than the default of 1500 unless for specific investigations as this can significantly affect performance.
MinApiMsgTimeout
Minimum (in minutes) timeout period for API messages. Increase this parameter if you encounter a large amount of “Timeout on receive message” errors.
Default: 10
Range: 10-14400
RetryPrimary
Number of hours that must pass before retrying the primary DS-System connection after switching to a secondary connection. A value of -1 means “never retry”, and a value of 0 means “retry immediately”.
Default: 24
Range: -1 to 240
TcpSocketBuffer
Internal socket buffer size (in bytes). This value is used if it is larger than the default.
Default: 34752
Note: Parameter can be applied globally or to individual nodes for Grid DS-Clients.
VSSKeepAliveTimeout
Timeout period (in seconds) for DS-Client to receive a response for a VSS (Volume Shadow Copy) operation. The VSS operation fails after the timeout period.
Default: 300
Range: 60 to 3600
