Target
The Target tab contains settings specific to the target module of Storage Mirroring.
Target Mirror Capacity High Percentage—You can specify the maximum percentage of Windows system memory that
can contain mirror data before the target signals the source to pause the sending of mirror operations. The default setting
is
20.
Target Mirror Capacity Low Percentage—You can specify the minimum percentage of Windows system memory that
can contain mirror data before the target signals the source to resume the sending of mirror operations. The default
setting is
15.
Retry Delay for Incomplete Operations (seconds)—This option specifies the amount of time, in seconds, before retrying
a failed operation on the target. The default setting is
3.
Block Target Path(s) on Connection—You can block writing to the data located in the target paths. This keeps the data
from being changed outside of Storage Mirroring processing.
Move deleted files to the following location—This option allows you to save files that have been deleted, by moving them
to a different location on the target. When a file deletion is replicated to the target, instead of the file being deleted from
the target, the file is moved to the specified location. This allows for easy recovery of those files, if needed. If you enable
this option, specify where you want to store the deleted files.
NOTE: If you are going to use failover, any target paths that are blocked will automatically be unblocked during
the failover process so that users can modify data on the target after failover. During a restoration, the
paths are automatically blocked again. If you failover and failback without performing a restoration, the
target paths will remain unblocked. You can manually block or unblock the target paths by right-clicking
on a connection.
Do not block your target paths if you are using Full-Server Failover because system state data will not be
able to be written to the target.
