Source
The Source tab contains settings specific to the source module of Storage Mirroring.

Replication Packets to 1 Mirror Packet—You can specify the ratio of replication packets to
mirror packets that are placed in the source queue. Specify a larger number if you have a busy
network that has heavy replication. Also, if you anticipate increased network activity during a
mirror, increase this number so that the replication queue does not get too large.

Replicate NT Security by Name—This is a Windows option only.

Ignore Delete Operations—This option allows you to keep files on the target machine after they
are deleted on the source. When a file is deleted on the source, that delete operation is not sent
to the target. (All edits to files on the source are still replicated to the target; only deletions of
whole files are ignored.) This option may be useful to give you an opportunity to make a backup
of these files in the event they are needed in the future.

Maximum Pending Mirror Operations—This option is the maximum number of mirror
operations that are queued on the source. The default setting is 1000 . If, during mirroring, the
mirror queued statistic regularly shows low numbers, for example, less than 50 , this value can
be increased to allow Storage Mirroring to queue more data for transfer.

Size of Mirror Packets—This option determines the size of the mirror packets that Storage
Mirroring transmits. The default setting is 32768 bytes.
NOTE: If delete operations are ignored long enough, the potential exists for the target to run
out of space. In that case, you can manually delete files from the target to free space.
