public void setVolumeUsedInBytes(Long volumeUsedInBytes) {

<p>
The size of the data stored on the volume in bytes. This value is calculated based on the number of blocks that
are touched, instead of the actual amount of data written. This value can be useful for sequential write patterns
but less accurate for random write patterns. <code>VolumeUsedInBytes</code> is different from the compressed size
of the volume, which is the value that is used to calculate your bill.
</p>
<note>
<p>
This value is not available for volumes created prior to May 13, 2015, until you store data on the volume.
</p>
<p>
If you use a delete tool that overwrites the data on your volume with random data, your usage will not be
reduced. This is because the random data is not compressible. If you want to reduce the amount of billed storage
on your volume, we recommend overwriting your files with zeros to compress the data to a negligible amount of
actual storage.
