问题解答

在涉及量分库的三向备份配置中、大型文件还原可能会失败。

备份供应商向文件管理器发送ndmpd中止。较小规模的恢复不会出现此问题。

在涉及量分库的三向备份配置中、大型文件还原可能会失败。在文件管理器构建目录和文件结构的还原阶段、文件管理器和磁带驱动器之间没有太多通信、因此TCP窗口大小会缩减为零。量子NDMP代码无法很好地处理这种情况、会重置连接并通知备份应用程序还原失败。然后、备份供应商向文件管理器发送ndmpd中止。较小规模的恢复不会出现此问题。

QUUM已在固件、网络数据管理协议(NDMP) v2.19中修复此错误。此版本不是通用版本、但您可以从"QUA腾"请求修复。部件号为6311408-10。
