Data transmission
Storage Mirroring Recover data is continuously transmitted to the target machine.
Although the data may be queued if the network or target machine is slow, the default
transmission setting is to transmit the data as soon as possible. You can modify the
transmission to suit your environment.
● Stopping, starting, pausing, and resuming transmission—You can maintain the
source/target connection, but still control the transmission of data across the
network by using the manual transmission controls. If transmission is paused, the
data is queued on the source until you manually restart the transmission.
● Scheduling data transmission—You can set event driven or scheduling criteria to
determine when data is transmitted. Data is queued on the source until the event or
schedule is met. Also, transmission can be stopped by using these criteria.
Scheduled transmission options can be toggled on and off, allowing you to enable
them only when you need to use them.
● Limiting transmission bandwidth—You can specify bandwidth limitations to restrict
the amount of network bandwidth used for Storage Mirroring Recover data
transmissions. Data is queued on the source until bandwidth is available.
Bandwidth limitations can be full-time or scheduled.
● Compressing data for transmission—You can compress data to reduce the amount
of bandwidth needed to transmit Storage Mirroring Recover data.
