Types of files
Data Classification scans all files for category and metadata insights and displays all file types in the file types section of the dashboard. When Data Classification detects Personal Identifiable Information (PII) or when it performs a DSAR search, only the following file formats are supported:
.CSV, .DCM, .DOC, .DOCX, .JSON, .PDF, .PPTX, .RTF, .TXT, .XLS, .XLSX, Docs, Sheets, and Slides
Accuracy of information found
NetApp can't guarantee 100% accuracy of the personal data and sensitive personal data that Data Classification identifies. You should always validate the information by reviewing the data.
Based on our testing, the table below shows the accuracy of the information that Data Classification finds. We break it down by precision and recall:
- Precision
-
The probability that what Data Classification finds has been identified correctly. For example, a precision rate of 90% for personal data means that 9 out of 10 files identified as containing personal information, actually contain personal information. 1 out of 10 files would be a false positive.
- Recall
-
The probability for Data Classification to find what it should. For example, a recall rate of 70% for personal data means that Data Classification can identify 7 out of 10 files that actually contain personal information in your organization. Data Classification would miss 30% of the data and it won't appear in the dashboard.
We are constantly improving the accuracy of our results. Those improvements will be automatically available in future Data Classification releases.
