Re: Database disaster risk and backups
You might want to take a look at using RDS. The backup options there are much better, and you can access the database through your favorite SQL client. They use a transaction log, which means you can recover to a specific point in time. Also, they've got these nifty Read Replicas which can be a big help if you need a reporting database or something similar. It's important to remember that you might want to access a backup due to bugs in your code that destroy data, or some kind of blunder by your DBA. It's not enough to know that Heroku can recover from their own train wrecks. On Nov 17, 10:03 am, Paul Dowman p...@pauldowman.com wrote: Thanks for the reply. So it's not actually possible to guarantee that there will be no data loss, the best we can do is an hourly backup (assuming the data set is small enough that a full dump each hour is feasible). So why does the marketing page (http://heroku.com/how/architecture) say that there's replication?

On Tue, Nov 16, 2010 at 1:34 PM, Paul Dowman p...@pauldowman.com wrote: Hey Heroku guys, just bumping this thread. To summarize: do we need to do automated regular backups to protect against Postgres or some other part of Heroku infrastructure going down, or is the database guaranteed to be reliable? We take automated backups as disaster insurance, but make no promises about their intervals. In the event of an outage, we handle recovery. If there is the potential for data loss, we reach out to any affected users. I'm guessing we do, and if so how do we do that since an hourly dump of postgres via cron isn't reliable enough or scalable? (i.e. you can lose up to an hour of data, and more as the dump starts to take longer with a large dataset.) Hourly dumps is probably your best solution at the moment, but we're aware that there are better solutions out there and would love to schedule those into our release schedule some time soon. Having said that, in the three years we've been running PostgreSQL, I believe the number of data-loss failures (and by that I mean restore-from-backup failures) could be counted on one hand. -pvh -- You received this message because you are subscribed to the Google Groups Heroku group.

Re: Heroku down time today, about 30 minutes total
So, 3 nine's is what to expect from Heroku? On Oct 28, 3:50 am, Peter Marklund peter_markl...@fastmail.fm wrote: Regardless with hosting option you choose you will have downtime. I have found more often than not the reason is to do with infrastructure like power, networking, hardware, routing etc. that will most likely be out of your control.

Heroku, SSL, iPhone, Safari, SAN: Can it be done?
Hi, if you have a site that meets the following criteria, will you please send me your site's URL, let me know where you bought your certificate, and how you got it to work? 1) Your site is hosted on Heroku (we're using IP-based SSL) 2) On iPhone/Safari, you can go to https://www.yourdomain.com (note the https). Also on Ubuntu/Firefox and desktop versions of Safari. 3) On those same browsers, you can go to https://yourdomain.com (note the https again, no www). 4) www.yourdomain.com is the common name, and yourdomain.com is a SAN on the cert. 5) No warnings pop up. I've already seen all of these links, and they are not enough to solve the problem: http://docs.heroku.com/ssl#custom-domain-ssl-wwwyourdomaincom http://www.thusa.co.za/blog/warwick-chapman/howto-generate-rsa-private-key-generate-csr-request-certificate-and-use-certifi http://matthodan.blogspot.com/2010/06/how-to-setup-heroku-godaddy-standa.html -- You received this message because you are subscribed to the Google Groups Heroku group.

Re: If you reserve full instance for custom SSL - why don't I get more dynos?
Hi, In general I am very happy with Heroku and their rates but I think Wojciech has a reasonable point. Yours, Husain On Tue, Dec 8, 2009 at 10:48 AM, Wojciech Kruszewski wojci...@oxos.plwrote: Hi, I've read your explanation about why you charge $100/mo for custom SSL (http://docs.heroku.com/ssl#faq). You need exclusive IP, Amazon assigns only one IP for an instance, so you need to reserve full instance just to use one SSL cert - seems fair. Ok, but if you reserve full EC2 instance just for me... then why do I have to pay for extra dynos? Aren't you double-billing for this instance?
