This files describes API changes in /backup/*, information provided here is intended especially for developers. === 3.1 === * New close() method added to loggers so they can close any open resource. Previously any backup and restore operation using the file logger may be leaving unclosed files. * New destroy() method added to loggers, normally called from backup and restore controllers own destroy() method to ensure that all references in the chained loggers are deleted and any open resource within them is closed properly. === 3.0 === * The backup_auto_keep setting, in automated backups configuration, is now renamed to backup_auto_max_kept as part of a rationalise of naming (see MDL-50602) === 2.6 === * The backup_controller_dbops::create_temptable_from_real_table() method is not available anymore. Temp tables must be created inline always. * Using the info field from backup_ids_temp or backup_files_temp must now go via backup_controller_dbops::decode_backup_temp_info() and backup_controller_dbops::encode_backup_temp_info(). The implementation of the encoding has changed. These new functions encapsulate any future changes to the encoding. === 2.5 === * New optional param $sortby in backup set_source_table() allows to specify the ORDER BY clause to be used. Previously it was required to use the set_source_sql() more complex alternative in places requiring ordering. * The old 1.9 files backuplib.php, lib.php and restorelib.php and the bb directory, (all under /backup) have been deleted and no code should rely on them anymore. === 2.4 === * Since 2.3.1+ the backup file name schema has changed. The ID of the course will always be part of the filename regardless of the setting 'backup_shortname'. See MDL-33812. === 2.3 === * Since 2.3.1+ the backup file name schema has changed. The ID of the course will always be part of the filename regardless of the setting 'backup_shortname'. See MDL-33812. === 2.2 === * Since 2.2.4+ the backup file name schema has changed. The ID of the course will always be part of the filename regardless of the setting 'backup_shortname'. See MDL-33812.
