If backup resides on the snapshotted file system a persistent snapshot will be created. This snapshot is active until backup is unlinked. This snapshot mode is only supported for ffs files systems.
Otherwise data written through the path will be saved in backup. If backup is a regular file, it will be created with length size. Default size is the size of path. Data is saved to backup in units of cluster bytes.
