I was asked to look at a SQL Server by a business software solution company. Performance issues. I did a current system state assessment and found that there were no backups or maintenance occurring. This seems to be a common and consistent problem, especially with companies who do not have any DBA skills. But what I did find was that every 2 hours they were taking a snapshot of the whole VM using Datto. This did have a performance impact and chewed up a lot of disk space.

We implemented backups and maintenance using Ola Hallengren's scripts and the VM snapshots became 3 a day - one before business starts, one at lunch and the last at close of business. I still think this is overkill, but a big improvement. Plus doing index optimisation is such a no brainer.
