错误:副本不一致Error: Replica is inconsistent

副本可能出于以下原因而不一致:A replica can be inconsistent for the following reasons:

  • 副本创建作业失败。The replica creation job fails.
  • 更改日记存在问题。There are issues with the change journal.
  • 卷级筛选器位图包含错误。The volume level filter bitmap contains errors.
  • 源计算机意外关闭。The source machine shuts down unexpectedly.
  • 同步日志溢出。The synchronization log overflows.
  • 副本确实不一致。The replica is truly inconsistent.

若要解决此问题,请执行以下操作:To resolve this issue, perform the following actions:

  • 若要消除不一致状态,请手动运行一致性检查,或计划每日一致性检查。To remove the inconsistent status, run the consistency check manually, or schedule a daily consistency check.
  • 确保使用最新版本的 Azure 备份服务器和 Data Protection Manager。Ensure that you're using the latest version of Azure Backup Server and Data Protection Manager.
  • 确保启用“自动一致性”设置。Ensure that the Automatic Consistency setting is enabled.
  • 尝试从命令提示符重启服务。Try to restart the services from the command prompt. 使用 net stop dpmra 命令,后接 net start dpmraUse the net stop dpmra command followed by net start dpmra.
  • 确保符合网络连接和带宽要求。Ensure that you're meeting the network connectivity and bandwidth requirements.
  • 检查源计算机是否意外关闭。Check if the source machine was shut down unexpectedly.
  • 确保磁盘正常,并且有足够的空间用于副本。Ensure that the disk is healthy and that there's enough space for the replica.
  • 确保没有重复的备份作业在同时运行。Ensure that there are no duplicate backup jobs that are running concurrently.

错误:在线恢复点创建失败Error: Online recovery point creation failed

若要解决此问题,请执行以下操作:To resolve this issue, perform the following actions:

  • 确保使用最新版本的 Azure 备份代理。Ensure that you're using the latest version of the Azure Backup agent.
  • 尝试在保护任务区域中手动创建恢复点。Try to manually create a recovery point in the protection task area.
  • 确保对数据源运行一致性检查。Ensure that you run a consistency check on the data source.
  • 确保符合网络连接和带宽要求。Ensure that you're meeting the network connectivity and bandwidth requirements.
  • 当副本数据处于不一致状态时,请创建此数据源的磁盘恢复点。When the replica data is in an inconsistent state, create a disk recovery point of this data source.
  • 确保副本存在而未缺失。Ensure that the replica is present and not missing.
  • 确保副本有足够的空间用于创建更新序列号 (USN) 日记。Ensure that the replica has sufficient space to create the update sequence number (USN) journal.

错误:无法配置保护Error: Unable to configure protection

如果 Data Protection Manager 服务器无法访问受保护的服务器,则会出现此错误。This error occurs when the Data Protection Manager server can't contact the protected server.

若要解决此问题,请执行以下操作:To resolve this issue, perform the following actions:

  • 确保使用最新版本的 Azure 备份代理。Ensure that you're using the latest version of the Azure Backup agent.
  • 确保在 Data Protection Manager 服务器与受保护服务器之间建立连接(网络/防火墙/代理)。Ensure that there's connectivity (network/firewall/proxy) between your Data Protection Manager server and the protected server.
  • 若要保护 SQL 服务器,请确保“登录属性” > “NT AUTHORITY\SYSTEM”属性显示已启用“sysadmin”设置。If you're protecting a SQL server, ensure that the Login Properties > NT AUTHORITY\SYSTEM property shows the sysadmin setting enabled.

错误:未根据保管库凭据文件中的指定注册服务器Error: Server not registered as specified in vault credential file

此错误是在恢复 Data Protection Manager/Azure 备份服务器数据的过程中发生的。This error occurs during the recovery process for Data Protection Manager/Azure Backup server data. 在恢复过程中使用的保管库凭据文件不属于 Data Protection Manager/Azure 备份服务器的恢复服务保管库。The vault credential file that's used in the recovery process doesn't belong to the Recovery Services vault for the Data Protection Manager/Azure Backup server.

若要解决此问题,请执行以下步骤:To resolve this issue, perform these steps:

  1. 从 Data Protection Manager/Azure 备份服务器所注册到的恢复服务保管库中下载保管库凭据文件。Download the vault credential file from the Recovery Services vault to which the Data Protection Manager/Azure Backup server is registered.
  2. 尝试使用下载的最新保管库凭据文件将服务器注册到保管库。Try to register the server with the vault by using the most recently downloaded vault credential file.

错误:没有可恢复的数据,或选定的服务器不是 Data Protection Manager 服务器Error: No recoverable data or selected server not a Data Protection Manager server

此错误的原因如下:This error occurs for the following reasons:

  • 未将其他 Data Protection Manager/Azure 备份服务器注册到恢复服务保管库。No other Data Protection Manager/Azure Backup servers are registered to the Recovery Services vault.
  • 服务器尚未上传元数据。The servers haven't yet uploaded the metadata.
  • 选定的服务器不是 Data Protection Manager/Azure 备份服务器。The selected server isn't a Data Protection Manager/Azure Backup server.

如果已将其他 Data Protection Manager/Azure 备份服务器注册到恢复服务保管库,请执行以下步骤来解决此问题:When other Data Protection Manager/Azure Backup servers are registered to the Recovery Services vault, perform these steps to resolve the issue:

  1. 确保安装最新的 Azure 备份代理。Ensure that the latest Azure Backup agent is installed.
  2. 确保安装最新的代理后,先等待一天,然后启动恢复过程。After you ensure that the latest agent is installed, wait one day before you start the recovery process. 夜间备份作业会将所有受保护的备份的元数据上传到云。The nightly backup job uploads the metadata for all of the protected backups to the cloud. 然后,可以使用备份数据进行恢复。The backup data is then available for recovery.

错误:提供的加密通行短语与服务器的通行短语不匹配Error: Provided encryption passphrase doesn't match passphrase for server

此错误是在加密 Data Protection Manager/Azure 备份服务器数据的过程中发生的。This error occurs during the encryption process when recovering Data Protection Manager/Azure Backup server data. 恢复过程中使用的加密通行短语与服务器的加密通行短语不匹配。The encryption passphrase that's used in the recovery process doesn't match the server's encryption passphrase. 因此,代理无法解密数据,恢复失败。As a result, the agent can't decrypt the data and the recovery fails.

Important

如果忘记或遗失了加密通行短语,则没有其他任何方法可恢复数据。If you forget or lose the encryption passphrase, there are no other methods for recovering the data. 唯一的办法就是重新生成通行短语。The only option is to regenerate the passphrase. 使用新的通行短语来加密今后的备份数据。Use the new passphrase to encrypt future backup data.

恢复数据时,请始终提供与 Data Protection Manager/Azure 备份服务器关联的相同加密通行短语。When you're recovering data, always provide the same encryption passphrase that's associated with the Data Protection Manager/Azure Backup server.
