Providing DBA services for a mid-size mid-west company. Duties include installation, optimization, trouble-shooting, backups, restores, and occasionally a little report writing. I have worked with SQL Server since v6.0.
My current SQL Server farm holds ~7.5 TB of data, >2000 databases, on 35 production instances with 17 hot/warm failover instances, plus a large set of QA/dev instances. In addition, I look after a bunch of MySQL databases, ~2 TB, and a little RavenDB instance. In my farm, no two production instances are alike.
