I have billing system on GAE. It is thing to have backup of my datastore. Now I have small record count and can read all of it for backup every day. But in future - I need any incremental method of backup my data. I have 3 things: - log operations in logging system and replicate on my server. - log operations in log kind and replicatite on my server (but it add pay for write, read and delete operations for each logical change in datastore). - save timestamp field in my entities and log of deleted object.
save data small in log - cheap and faster then write it in datastore. 2011/9/29 Jan Zawadzki / Hapara <[email protected]> > This only works if you don't have a lot of traffic. > > As Ikai mentioned, these are limited-size FIFO logs, so if you start > hitting any significant traffic, you will find that your INFO logs > hold a minute's worth of data - longer than a transfer would take you. > > Write to a DB, OR, use RPC and URL fetch to "ping" an external server > that will store the Apache log files for you. > > J > > On Sep 28, 10:06 am, rekby <[email protected]> wrote: > > Do log record gurantee for each request - I want write into log > instructions > > for incremental change data and make incremental backup on my computer by > > download and parse log messages instead of analise datastore. > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/google-appengine?hl=en. > > -- С уважением, Кулин Тимофей.
