For resource security, to prevent the SVN configuration library resources from being lost and unrecoverable due to hardware or software failures of the configuration management server, you need to back up the configuration library resources regularly. The backup strategy adopted here is "regular large backups and hourly small backups" , that is, the overall backup of all configuration library resources under the root directory of the configuration library is regularly performed. For each configuration library, if the resources in the library are effectively modified ( That is, if the resource is modified and successfully submitted), only the modified information content is backed up.
