Hi Aral,

This tool is so awesome! Thanks so much for creating it. Do you know of any way to auto backup your GAE datastore to Amazon S3? That would be the holy grail :-)

Thanks,
David

I just installed the gaebar in my application.

After a few tries I was able to make a backup of my data (I got some Timeout errors, but today datastore was in anomaly with high latency times).

My first comment: Awesome!

When I input data in the local server,
model.key().id() returns its numerical ID properly
but when I upload it to google server by gaebar,
model.key().id() returns null

Any one experienced in this issue?

Hi … I had a lot of trouble making gaebar work with aep 1 … but I finally got it up & running.

Some hints in case you had the same problems I did:

1) AEP uses by default a Django Style naming (app_model vs Model) and this has conflicts with gaebar (0.3) … so I had to use the patch provided by Alexander Vasiljev (http://groups.google.com/group/app-engine-patch/browse_thread/thread/441ad1a7a47cf59b/f0007e42a53924a9#f0007e42a53924a9)

2) After applying the patch, GAEBAR worked perfectly on my localhost, but it did not work at the deployment server (appspot.com). I got 500 errors and MANY shard files .

The problem this time was with the index.yaml. For some reason my index.yaml file was not updated with new indexes, and this produced an error at the deployment server.

I manually added the following index definition and it finally worked smoothly:

- kind: gaebar_gaebarcodeshard
properties:
– name: backup
– name: created_at

P.S.: After erasing my index.yaml file, the development server started updating the index.yaml file again (automatically)

Hope this helps …

Hi Ernesto,

yes, I applied the patch but it didn’t have any effect with App Engine 1.1.9 and 1.2.0.

Hi Stefan …

Did you remember to “*IMPORTANT* Patch your dev_appserver.py as per the instructions here: http://aralbalkan.com/1440”

When I updated … my dev_appserver.py was also updated and the patch was lost.

Hi, I tested gaebar with App Engine 1.1.8 and it works perfectly but it doesn’t work with App Engine 1.1.9 and 1.2.0. Any ideas how I can it make work?

1. remote_api
2. retry for datastore timeout
3. mutli-thread like bulkloader.py
