#Start Analysis

Refer to the following steps to start an analysis:

1. To start an analysis for the first time, on the Discovery page, click Start analysis. If you have started an analysis before, on the Discovery page, click Analyze again. Select Generate report data again and click Next to start a new analysis.

2. Select scope – Select the containers that contain the drives you want to include in the analysis.

3. Click Next.

4. Set reporting threshold – Predefined filters based on file size and modified time are displayed. You can customize these filters to meet your special requirements. These filters will be displayed on the inactive data report and ROT data report later, allowing you to effectively review the data.

5. Click Next.

6. Find inactive data – All files will be scanned based on the modified time to generate the inactive data report. Currently, you cannot create any rules to find inactive data.

   *Note: Google Drive saves every change made to a file automatically and you can manually name a version. Opus only scan files and their named versions; all unnamed, auto-saved versions generated by Google Drive are excluded from scanning.

7. Click Next.

8. Find ROT data – Create rules to find redundant, obsolete, and trivial data in the scope that you defined above:

   1. Turn on the toggle to analyze data size of ROT data.

   2. Switch among Redundant, Obsolete, and Trivial tabs to add the corresponding rules.

   3. There are built-in rules for you to reuse. Click the Expand () button next to a rule to view the detailed rule configurations.

      • To modify a rule, click the Edit () button next to the rule and modify the rule based on your needs.

      • If a rule is not usable, click the Delete () button next to the rule to delete it.

   4. To add a rule, click Add rule under an ROT category. Enter the rule name and description, configure rule criteria, and then click Save to save the changes. Refer to the table below for detailed rule criteria.

   5. Select the rules that you want to use to find ROT data.

9. Click Finish, and then click OK in the confirmation message. A discovery process will start, followed by an analysis process. You can find the progress below.

When the analysis is completed, the last analyzed time will be displayed. The last analyzed time is clickable, which will download a report, displaying the analysis scope and the status. You can navigate to Inactive data and ROT data to view the report details.

If you want to start a new analysis, you can click Analyze again to start a new analysis. There are two options to start a new analysis:
