Interesting trick for recruiting from Groupon

So a few days ago the wife was reporting problems with her e-mail and one of those e-mails she was having problems with was groupon. So I decided to take a look at the e-mail headers to figure out when they were sent and I found this little gem.

Backing up and Restoring your MySQL RDS Instance (and other Cloud DBs)

As more and more things move to the “cloud” as a Sys Admin you might find your self tasked with managing a Database that you don’t have shell access too. That has been the case for me with my last two jobs, Laughing Squid and now as Senior Sys Admin at Oxygen Cloud. With Oxygen we needed to backup some AWS RDS Instances and wanted to do it using a server on EC2 so we don’t have the bottle next of our local internet. This same method works with Rackspace Cloud Sites which I used at Laughing Squid. Its use a little known (could not find it easily with a google search) trick with mysqldump

mysqldump -P <port#> -h <server ip>-u mysql_user -p database_name table_name > backup.sql

To restore your DB in the cloud you use a more well-known mysql technique

mysql -u mysql_user -p -h <server ip> cloud_db_name < backup.sql
