# Agent Log Files

The Datadog Agent does a logs rollover every 10MB by default. When a rollover occurs, one backup (`agent.log.1`) is kept. If a previous backup exists, it is overwritten during the rollover. To set the maximum size of one log file and the maximum number of backup files to keep, use `log_file_max_size`(default: 10485760 bytes) and `log_file_max_rolls`(default: 1) in the [Agent configuration file](https://docs.datadoghq.com/agent/configuration/agent-configuration-files.md?tab=agentv6v7#agent-main-configuration-file).
