When incremental saved configuration files are enabled, the system saves each configuration commit to the configure configuration region in a separate incremental saved configuration file, instead of saving a complete saved configuration file each time. This mechanism makes commits over model-driven interfaces (the MD-CLI, NETCONF and gRPC/gNMI) much faster, because less configuration needs to be saved.
When the system boots or the rollback command is issued, the last complete saved configuration file is loaded first, and then any required incremental saved configuration files are loaded in the sequence they were committed to apply the previous saved configuration.
The commit history displays information about incremental and complete saved configuration files. The "Location" field displays the complete saved configuration file location, and the "Increment" field displays the incremental saved configuration file location. When the "Location" field is not displayed, the incremental saved configuration file in the "Increment" field is loaded as described above

A background process generates a complete saved configuration file periodically to reduce the number of incremental saved configuration files that are needed by system. The commit history is updated with a "Location" field like in the following example.

Incremental saved configuration files are enabled with the configure system management-interface configuration-save incremental-saves command, and must be configured together with the following constraints.
The following usage guidelines apply.
