We are building a Veeam solution primarily designated for customers (Backup as a Service Solution). We currently use Veeam to backup our production environment which consists of around 80 VMs and about 20TB of data. This second instance of Veeam will be independent of our production instance.
I have been unable to find in-depth information regarding the usage of SQL Server Standard over Express except for a small blurb on page 145 of the veeam_backup_7_userguide_vmware.pdf that states the following:
Due to its limitations, Microsoft SQL Server Express Edition should only be used for evaluation purposes or in case of a small-scale production environment. For environments with a lot of VMs, it is necessary to install a fully functional commercial version of Microsoft SQL Server.
The current database size in our production environment is around 270MB and its uses SQL Express 2005. SQL Express 2008R2 is now included in Veeam 7. This version of express supports up to 10GB databases but with the same limitations in terms of CPU cores and memory usage.
I am trying to find the justification to purchase a SQL Server standard license instead of using the express edition for this environment.
Any information would be greatly appreciated.
