How to springboot Logback Prevent deleting of older Log files

My spring-boot application keeps archive logs for only 7 days as defined in the defaults as defined in the logging defaults.

The issue is that I need these logs to always be there and never be deleted.

Is there a way to specify this?

sample Config

logging:
  file:
    name: logs/application.log
  file.max-size: 200MB
  level:
    org.apache.http: INFO
    org.springframework.cloud.sleuth: INFO
    org.springframework.web: INFO

According to the logback documentation, setting maxHistory to zero disables archive removal and setting totalSizeCap to zero disables archive removal by combined size threshold. However, it is mentioned that "The totalSizeCap property requires maxHistory property to be set as well". The maxHistory of default FileAppender in Spring Boot is 7 by default. So, setting

logging.logback.rollingpolicy.max-history=0

in your application properties might do the trick.

logging:
  logback:
    rollingpolicy:
      max-file-size: 0
  file:
    name: logs/application.log
    max-size: 200MB
  level:
    org:
      apache:
        http: INFO
      springframework:
        cloud:
          sleuth: INFO
        web: INFO
