  1. Even though NSS volumes support compression, they only report compression metrics at the volume level, not on a per-file basis.

  2. File size-on-disk calculations are currently performed using an assumed 4 KB block size, except when using AgentFS for Windows file systems, which attempts retrieval of the actual allocation size.

  3. Access and Modify time stamps for directories are not consistently defined across file system types. These time stamps should only be considered for file entries.

  4. Directory Quotas for Windows NTFS volumes are only available on Windows 2008 R2 and later servers, and only if the File Server Resource Manager (FSRM) Role has been installed.

  5. Scanning of NSS 64 volumes is supported only by:

    • Agent for OES Linux running on OES 2015 SP1 or later

    • Legacy Agent for Windows running on Windows Server 2008 R2 or later with OES Client 2 SP4 or later
