从任务队列运行appengine备份 [英] Run appengine backup from task queue
问题描述
在Google App Engine的 1.8.4版本中，它指出： / p>
In the 1.8.4 release of Google App Engine it states:
此版本中的Datastore管理修复程序通过确保计划备份现在只能由cron或任务队列任务启动来提高安全性。管理员仍然可以通过管理控制台中的数据存储管理员启动备份。
A Datastore Admin fix in this release improves security by ensuring that scheduled backups can now only be started by a cron or task queue task. Administrators can still start a backup by going to the Datastore Admin in the Admin Console.
使用cron运行计划备份的方法，但是如何从任务队列任务启动备份？
The way to run scheduled backups with cron is documented, but how can we initiate backups from a task queue task?
有没有其他方法以编程方式运行备份任务？
Are there any other ways to programmatically run backup tasks?
推荐答案
您可以使用方法GET和URL/_ah/datastore_admin/backup.create创建具有指定为URL参数的参数的任务队列任务，并将目标任务运行在ah-builtin-python-bundle版本上。示例：
You can create a task queue task with method GET and URL "/_ah/datastore_admin/backup.create" with your parameters specified as arguments to the URL and target the task to run on the 'ah-builtin-python-bundle' version. Example:
url = '/_ah/datastore_admin/backup.create?filesystem=blobstore&name=MyBackup&kind=Kind1&kind=Kind2'
taskqueue.add(
url=url,
target='ah-builtin-python-bundle',
method='GET',
)
我有cron作业触发我自己的处理程序，然后查找配置并创建任务队列基于该配置进行备份。这允许我更改备份设置，而不必更新cron作业，并让我有更多的控制。
I have cron jobs that trigger my own handlers that then look up a config and create a task queue backup based on that config. This lets me change backup settings without having to update cron jobs and lets me have a lot more control.
您可以在URL中指定的选项与文档相同描述 CRON作业备份，以便您可以将namespace和gs-bucket-name指定为
The options you can specify in the URL are the same as the documentation describes for CRON job backups so you can specify namespace and gs-bucket-name as well.
我相信在Java中这样做，你必须在队列定义中创建一个带有目标的队列，并将你的任务添加到队列中。
I believe to do this in Java you have to create a queue with a target in the queue definition and add your tasks to that queue.
