Answer

  • Meaning of high entropy data write percentage
    • Displays the peak historical percentage of high entropy data within incoming write operations.
    • Represents the proportion of encrypted or highly random data observed in the total writes to the volume.
  • What the percentage represents
    • Percentage of incoming data determined to contain high entropy.
    • Calculated from the entire set of incoming writes to the volume, not from specific folders or subsets.
    • Reflects all data written to the volume, regardless of file type or extension.
  • Which files and operations are included
    • All files written in the volume are included in the high entropy data evaluation.
    • ARP does not limit calculation to only the files created or modified after ARP enablement.
    • High entropy data assessment applies to the full incoming write stream that reaches the volume.
