    immutable = not changeable?

    Set "Readonly" property on file system level, as for any other file.

    • Cloud Storage Options
    • Hardware Solutions
    • Backup Software with Immutable Features
    • File System-Level Immutability

    You could refer to this article to get more information, hope this can help you well!
