NetBackup是用mtime来确定增量备份的\r\n如果mtime是 1月20日,而全备份的时间是2月1日,netbackup认为这些文件应该包\r\n括在2月1日的全备份中,它的增量备份只被mtime>2月1日的文件\r\nWhen a file is moved from one location to another, the ctime of the file\r\nchanges, but the mtimeremains unchanged. If NetBackup is only using the\r\nfile modification time (mtime) to determine files due to be backed up\r\nduring an incremental backup, it will not detect these moved files. For\r\nsites where this is an issue, the ctime should also be used (if\r\npossible) to determine files due to be included in an incremental\r\nbackup, using the bp.conf attributes USE_CTIME_FOR_INCREMENTALS and\r\nDO_NOT_RESET_FILE_ACCESS_TIME. |
