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.

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
tab
