QueryChangedDiskAreasRequestType
The parameters of QueryChangedDiskAreas.
{
"snapshot": {
"_typeName": "string",
"type": "string",
"value": "string"
},
"deviceKey": 0,
"startOffset": 0,
"changeId": "string"
}
Reference to an instance of the VirtualMachineSnapshot managed object.
Identifies the virtual disk for which to compute changes.
Start Offset in bytes at which to start computing changes. Typically, callers will make multiple calls to this function, starting with startOffset 0 and then examine the "length" property in the returned DiskChangeInfo structure, repeatedly calling queryChangedDiskAreas until a map forthe entire virtual disk has been obtained.
Identifyer referring to a point in the past that should be used as the point in time at which to begin including changes to the disk in the result. A typical use case would be a backup application obtaining a changeId from a virtual disk's backing info when performing a backup. When a subsequent incremental backup is to be performed, this change Id can be used to obtain a list of changed areas on disk.
