vSphere Is Not the Performance Problem, Your Storage Is « Pivot Point
Despite the explosion of VMware into the data center we remain the new kid on the block. As soon as performance suffers the first reaction is to blame the new kid. But next time you see a performance problem in your production environment, I urge you to look at the issue as a consolidation challenge, and not a virtualization problem. Follow the best practices you have been using for years and you can correct this problem without needing to call me and my colleagues to town.

Tibor Karaszi's SQL Server pages
There's no support at the TSQL level to keep generations of backups. For instance, you want to keep backups for 3 days. The functionality is available in Maintenance Plans (MP), but sometimes you want a higher degree of customization.
