+drive-backup
+------------
+
+Start a point-in-time copy of a block device to a new destination. The
+status of ongoing drive-backup operations can be checked with
+query-block-jobs where the BlockJobInfo.type field has the value 'backup'.
+The operation can be stopped before it has completed using the
+block-job-cancel command.
+
+Arguments:
+
+- "device": the name of the device which should be copied.
+ (json-string)
+- "target": the target of the new image. If the file exists, or if it is a
+ device, the existing file/device will be used as the new
+ destination. If it does not exist, a new file will be created.
+ (json-string)
+- "format": the format of the new destination, default is to probe if 'mode' is
+ 'existing', else the format of the source
+ (json-string, optional)
+- "mode": whether and how QEMU should create a new image
+ (NewImageMode, optional, default 'absolute-paths')
+- "speed": the maximum speed, in bytes per second (json-int, optional)
+- "on-source-error": the action to take on an error on the source, default
+ 'report'. 'stop' and 'enospc' can only be used
+ if the block device supports io-status.
+ (BlockdevOnError, optional)
+- "on-target-error": the action to take on an error on the target, default
+ 'report' (no limitations, since this applies to
+ a different block device than device).
+ (BlockdevOnError, optional)
