[google-appengine] Re: Are there any data recovery mechanisms for google app engine database?
If data is deleted mistakenly or even intentionally can be restored if you have prepared yourself with the backups of that data. If not having backup then with third party data recovery tools, data files can be recovered easily. Various file recovery softwares are available and you can try one named Kernel for Windows.. Bingo!! http://www.windowsrecoverysoftware.com/ Thanks On Jul 30, 9:22 am, DiveIntoGAE taogf1...@gmail.com wrote: If I delete some important datas by mistake, how can I recover them? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
