    Hi Alexis,

     

    Thanks for your feedback.

    1) It is reasonable that "Nx Witness" can't and shouldn't delete any files that were not generated by Nx.
    An ideal and proper option is that you are suggested prepare a dedicated place that is separated from other data.
    If you are using a NAS - A dedicated volume or limited size shared folder would be good.
    If you are using a local HDD - A dedicated partition or HDD for recording would be highly recommended,

    The reason is that Nx Witness grabs the capacity of your drives via the system call, meaning that the OS returns the capacity to Nx. Then Nx would try to use the whole capacity, however, if there are some files that were not generated by Nx, the software won't be able to recycle the files for recording ideally.

     2) If you set the fixed archive length, meaning you force the Nx Witness drops its default recycling policies. However, if there is no any free space for the new recording, your existing recording files (even with the tag of fixed length) would be removed due to the new recording still need to be written to the storage.

    3) The warning noise comes from an improper storage configuration, so it is likely not noise but a reminder. It is suggested you can consider isolating the recording drives and others. It would give you better performance and clear usage of your storage. It is also suggested that you should keep the Nx recycling policies by default unless you really have limited spaces of the storage or specific purposes that need to keep some footage. Using the fixed-length archive option to workaround the storage warning on a mixed-purposes HDD is not suggested.

    4) Thinking the recording is a super heavy load for HDD, if you have some data on the same drive, once the HDD is died due to the mechanical lifetime, then your data would be gone as well. So, it is still not suggested you mix the purpose of recording and daily data storing on the same HDD/storage. 

     

    Thanks.

    Hi

    NX was recording to its own dedicated shares. Nothing else in them.

    Because its a NAS, Unraid can worry about the data integrity should a drive die, that's why its on a NAS in the first place.

    Hi Alexis, 

    Thanks for your response. 
    When you are using NAS, you could create a volume for it. Then Nx could use that volume.

    A dedicated shared folder but no space limitation would still affect other data.
    As we mentioned, the capacity was returned by the standard OS system call, so it means the OS would return the number of the whole capacity of the volume. 

    However, sometimes even though you limit the size of the folder on a NAS, it just restricted the write operations, but the number of the capacity returned by OS would still be the whole volume.

    As a result, this warning tends to a reminder. it tells you that Nx can't recycle some files and might not be able to use the whole space and if you have some data on the same drive, once the HDD is died due to the mechanical lifetime, then your data would be gone as well.

    We appreciate your feedback and thanks for telling us your opinions.
    Thanks.
