google app engine - Disable datastore writes programatically when running scheduled backups? -

-

i running daily scheduled backup of datastore.. is possible programtically disable datastore writes when this scheduled backup being executed? , enable once it's done?

no, can't (13 jun 2013) disable datastore writes programmatically. if app checking capabilities api wrap described in google app engine datastore writes: how enable/disable read-only mode remotely? approach unavoidably prone race condition (you might check capability before gets disabled).

although parts of documentation suggest should set application read-only mode during backups , restores, in practise should fine backup while app still running, long app making appropriate use of transactions ensure consistency. other parts of docs such the article on scheduled backups don't suggest necessary.
