Continuous is intelligent overlapping incremental crawls. You'll still see "(I)" in the crawl log. This is expected.
Continuos crawl and incremental both running

Hi, I have a SP 2019 client. They have continuous crawl selected and still have the incremental crawl scheduled. In the crawl log, I found both incremental and continuous and Full are running. I thought when continuos runs then no incremental and full happen. ![66842-image.png][1] Am I correct? [1]: /api/attachments/66842-image.png?platform=QnA

2021-02-11T05:29:17.41+00:00 Should we do continuous, incremental and Full all these 3?
Is it recommended? -

2021-02-11T06:58:47.003+00:00 Recommendation is only Continuous. Full crawl is only required for the first time you crawl, when you update Managed Properties at the SSA level, or attempting to resolve a corrupt index. I do not recommend scheduling a full crawl.

Agree with trevor. In addition, About the selection of crawl type, It depends on the needs in your environment as different crawl types have different functions.
- As to
full crawl, it crawls entire content under a content source. Please take a reference to this article: Reasons to do a full crawl. - As to
incremental crawl, it crawls content that was added, changed, or deleted since the last crawl. - As to
continuous crawl, it crawls SharePoint Server sites frequently to help keep search results fresh. Like incremental crawls, a continuous crawl crawls content that was added, changed, or deleted since the last crawl. Unlike an incremental crawl, which starts at a particular time and repeats regularly at specified times after that, a continuous crawl automatically starts at predefined time intervals. The default interval for continuous crawls is every 15 minutes. Continuous crawls help ensure freshness of search results because the search index is kept up to date as the SharePoint Server content is crawled so frequently. Thus, continuous crawls are especially useful for crawling SharePoint Server content that is quickly changing. Please take a reference to this article: Manage continuous crawls in SharePoint Server
