l
Source IP Address—Select an IP address on the source to handle the
restoration data. In a cluster environment running Exchange, select the name
of Exchange virtual server dependent IP address.
l
Restore target data prior to failback—Select this option to restore data
from the target back to the source. If you are certain that there is no data that
you want to restore or you are willing to lose any data changes on the target,
you can disable this option.
l
Enable Compression—Compression allows you to reduce the amount of
bandwidth needed to transmit restoration data from the target back to the
source. The data is compressed before being transmitted and then is
uncompressed before it is written on the source. Typically, compression is
used in WAN environments, but not in LAN environments. If desired, enable
compression and select the level of compression that you want to use.
l
Prompt prior to failback—When this option is enabled, the failback process
will not start until you manually initiate it after the restoration is complete. You
will be prompted when the restoration process is complete. If you disable the
failback prompt, failback will automatically start when the restoration is
complete.
l
Mirror—Select the type of mirror to use for the restoration process. A Full
mirror will transmit all files from the target back to the target. A Checksum
mirror will transmit only the blocks of data that are different between the target
and source.
