NetBackup是用mtime来确定增量备份的
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
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
When a file is moved from one location to another, the ctime of the file
changes, but the mtimeremains unchanged. If NetBackup is only using the
file modification time (mtime) to determine files due to be backed up
during an incremental backup, it will not detect these moved files. For
sites where this is an issue, the ctime should also be used (if
possible) to determine files due to be included in an incremental
backup, using the bp.conf attributes USE_CTIME_FOR_INCREMENTALS and
DO_NOT_RESET_FILE_ACCESS_TIME. |
