I have used both. Internal SQL express, external SQL server, SQL server in an Always ON cluster replicated to our DR site.
All 3 worked great, I have never noticed a difference in performance, and never hit the limits.
Here are my questions about SQL and Veeam.
- Has anyone here ever hit the SQL Express limits?
- Has anyone here ever installed a full blown SQL instance on their Veeam server? Did this make much difference than an external SQL server?
We have a DB admin, so using external is pretty easy for me, but I really have no clue when I'll outgrow SQL Express. I suppose I can change it up in V12 as well with the new option.
