AppEngine数据存储 - 以编程方式进行备份 [英] AppEngine datastore - backup programmatically

问题描述

我希望以编程方式定期备份应用的数据存储。

根据创建一个备份数据存储的cron似乎是可能的href =https://developers.google.com/appengine/articles/scheduled_backups =nofollow noreferrer> https://developers.google.com/appengine/articles/scheduled_backups

然而，我需要更加细致的解决方案：为动态更改的名称空间创建不同的备份文件。

是否可以简单地使用GET / POST调用/_ah/datastore_admin/backup.create url？

解决方案

是的;我正是这样做的，以实现一些无法用cron完成的逻辑。

使用taskqueue API添加URL请求，如下所示：

  from google.appengine.api import taskqueue 
 taskqueue.add（url ='/ _ ah / datastore_admin / backup.create '，
 method ='GET'，
 target ='ah-builtin-python-bundle'，
 params = {'kind'：（'MyKind1'，'MyKind2'）}） 
  

如果你想使用更多的参数，否则会进入cron url，比如'filesystem'，把那些参数字典放在'kind'旁边。

I would like to backup my app's datastore programmatically, on a regular basis.

It seems possible to create a cron that backs up the datastore, according to https://developers.google.com/appengine/articles/scheduled_backups

However, I require a more fine-grained solution: Create different backup files for dynamically changing namespaces.

Is it possible to simply call the /_ah/datastore_admin/backup.create url with GET/POST?

解决方案

Yes; I'm doing exactly that in order to implement some logic that couldn't be done with cron.

Use the taskqueue API to add the URL request, like this:

from google.appengine.api import taskqueue
taskqueue.add(url='/_ah/datastore_admin/backup.create',
              method='GET',
              target='ah-builtin-python-bundle',
              params={'kind': ('MyKind1', 'MyKind2')})

If you want to use more parameters that would otherwise go into the cron url, like 'filesystem', put those in the params dict alongside 'kind'.
