+drive-mirror
+------------
+
+Start mirroring a block device's writes to a new destination. target
+specifies the target of the new image. If the file exists, or if it is
+a device, it will be used as the new destination for writes. If it does not
+exist, a new file will be created. format specifies the format of the
+mirror image, default is to probe if mode='existing', else the format
+of the source.
+
+Arguments:
+
+- "device": device name to operate on (json-string)
+- "target": name of new image file (json-string)
+- "format": format of new image (json-string, optional)
+- "mode": how an image file should be created into the target
+ file/device (NewImageMode, optional, default 'absolute-paths')
+- "speed": maximum speed of the streaming job, in bytes per second
+ (json-int)
+- "granularity": granularity of the dirty bitmap, in bytes (json-int, optional)
+- "buf_size": maximum amount of data in flight from source to target, in bytes
+ (json-int, default 10M)
+- "sync": what parts of the disk image should be copied to the destination;
+ possibilities include "full" for all the disk, "top" for only the sectors
+ allocated in the topmost image, or "none" to only replicate new I/O
+ (MirrorSyncMode).
+- "on-source-error": the action to take on an error on the source
+ (BlockdevOnError, default 'report')
+- "on-target-error": the action to take on an error on the target
+ (BlockdevOnError, default 'report')
+
+The default value of the granularity is the image cluster size clamped
+between 4096 and 65536, if the image format defines one. If the format
+does not define a cluster size, the default value of the granularity
+is 65536.
