i'll share some things based on my interpretation.....happy to be educated if i get any of this wrong. :)
1. to my knowledge in 6 years i've never lost data. there have been outages and slowdowns, but i can't recall a single bit of data loss. Remember that BigTable (well, i think it's been renamed to Cloud Datastore or something....) is replicated. I suppose if you have 0 traffic you might get down to 1 copy, but at some traffic level there are at least 2 copies of your data. 2. good question. i assumed multiple data centers in the same region, but i don't know that for a fact. 3. i don't have a sane regime to recommend. :( sorry. cfh On Saturday, December 12, 2015 at 10:29:03 AM UTC-8, Richard Cheesmar wrote: > > Hi, All > > I have a few of questions regarding data security and sensible backup > routines. > > 1.
