Bit MapIt is the directory containing the intent log.

Compression level

It represents the compression level for a specific copy set. The setting range is from 0 to 9.
‘0’ means no compression. The greater the value is, the smaller bandwidth is used to transmit greater data. But also, it uses more of the CPU resources.
Thus, by properly balancing the system CPU usage and the network bandwidth, select the proper compression level that can maximize the efficiency.

Empty async queue

Even if a driver receives a request for deleting a queue, this function can be used to prevent deletion of queues on a specific volume.
Bandwidth 

It is the max network bandwidth (kbps/sec) that can be used by a copy set.
‘0’ means that the given bandwidth will be used with maximum efficiency.

Mirror network address Copy the volume to the set IP address.

Pausing Copy

If you command the pausing copy,
the volume condition will be changed to pause and copying will be paused.

Forceful SyncIf you use the forceful sync command,
the status will be changed to RESYNCING and the full synchronization will be done forcefully.
Resuming CopyResume to copy the mirror volume that was paused.
Resynchronization takes place if data is changed during temporary pause.

Target 

Lock

Lock the volume to prevent access anymore.

Unlock

Unlock the target volume to see the content of the file.
Warning

Unlock the target volume to see the content of the file. It can cause a negative effect to the mirror.
Even if you unlock it, you cannot write to the file. If you want to "write" to the file, you must manually change the readOnly attributes in the registry.
