Copying a USB stick with 30 GB data to the NAS doubles the data volume from 1,5 TB up to 4 TB

i copied data from a us stick of 30 gb onto the nas. the data volume doubled from the former 1.5 TB to almost 4 TB.

The USB stick was encrypted with mcafee.

Does anyone have any idea what the cause may be and how I could delete the incremental data ?

    Never seen this before.  The encryption of the drive shouldn't matter.

     

    Maybe delete some of the oldest snapshots and then run a balance from the volume settings wheel.

        Just startet the rebalancing process and the occopied volume reduces step by step.

        I am wondering what caused the doubling of the used data capacity. At the end the issue has been solved.

        Thank you for your help and guidance.

        Best
