dpm - 如何临时禁用 DPM 2012 计划备份？

Question

我需要暂时禁用 Hyper-V 服务器映像的一些计划备份。我看到的唯一选项是“停止保护成员”，这似乎删除了备份作业。如何禁用备份作业而不删除它？

运行 System Center 2012 DPM SP1

Answer 1

This is an old question, but I thought I'd add my two cents. I do not recommend the above solution except as a one-time special case. I have 47 Exchange CCR clusters backed up by an equal number of DPM servers, and I have to "pause" backups every time I do a failover or I run the risk of a failed database dismount during the failover. Removing the protection groups every time I needed to perform maintenance on a client machine would be a nightmare.

I recommend that you simply disable the DPMRA service on the client machine, and then stop it. The DPM server can continue running in this state. Backups will fail obviously, but as soon as you re-enable the service you can resume backups with no issue. Disabling/enabling the service is easily scripted in powershell, which is also a plus:

Disable:

Set-Service dpmra -StartupType Disabled
net stop dpmra

Enable:

Set-Service dpmra -StartupType Manual

Sometimes uninstalling the protection group is your only option, but I would not recommend using that as your go-to method for planned maintenance.

您可以安全地停止保护成员，在向导上指定保留数据。这将有效地停止计划但保留现有数据。当您要重新安排备份时，您必须重新创建保护组，因此请务必在停止保护之前记下配置（频率、类型等）。DPM 将自动意识到数据源存在以前的备份数据，并以此为起点。
请注意，当保护组不存在时，备份将不可用，因为实际上您不是暂停备份，而是停止 + 启动。
如果您将 DPM 视为复制软件而不是备份系统，则更容易理解。
