Note: Stopping, starting, pausing, or resuming mirroring contains a
comparison of how the file difference mirror settings work
together, as well as how they work with the global checksum
setting on the Source tab of the Server Properties.
l Remirror on Auto-Reconnect—In certain circumstances, for example if the
disk-based queues on the source are exhausted, Storage Mirroring Recover
will automatically disconnect connections (called auto-disconnect) and then
automatically reconnect them (called auto-reconnect). In order to ensure data
integrity on the target, Storage Mirroring Recover will perform an automatic
mirror (called an auto-remirror) after an auto-reconnect. If you enable this
option, specify the type of auto-remirror that will be performed.
l File Differences with Checksum—Any file that is different on the
source and target based on date, time, and/or size is flagged as
different. The mirror then performs a checksum comparison on the
flagged files and only sends those blocks that are different.
l File Differences with no Checksum—Any file that is different on the
source and target based on date, time, and/or size is sent to the target.
l Send data only if Source is newer than Target—Only those files that
are newer on the source are sent to the target.
Note: Auto-reconnect is a server-based setting, so all connections
from the same source will have the same auto-reconnect
configuration.
If you want to change the auto-reconnect setting after a
connection is established, you can do so from the Server
Properties Setup tab
Stopping, starting, pausing, or resuming mirroring contains a

l Full—All files are sent to the target.
