Mirroring—Select the type of Storage Mirroring mirroring process you want to perform. A Full
mirror will transmit all files from the source to the target. A Checksum mirror will transmit only
the blocks of data that are different between the source and target.
Estimate Replication Set size based on volume—If enabled, the replication set size is based
on the volume size, which is a faster calculation. If disabled, the replication set size is based on
the selected data, which can be a slower calculation.
Compression—Select the level of compression that you want to use. This reduces the amount of
bandwidth needed to transmit data from the source to the target. The data is compressed before
being transmitted and then is uncompressed before it is written on the target. If desired, you can
also disable Compression. Typically, compression is used in WAN environments, but not in LAN
environments.
After you have configured the settings on the various tabs, click OK to return to the main Full-Server
Failover Manager window.
NOTE:
The mirror will remain in an initializing state until the mirror calculation is complete.
