I found this archived thread that says you can do disaster recovery snapshot even with SQL Server Express.
I was told in another thread that you cannot create disaster recovery snapshots with SQL Express. We have ePO Sever 5.3.2 .
The ePO 5.3 product guide says using SQL Express with disaster recovery snapshot is "not recommend" due to database size limitations. It doesn't say it is impossible or unsupported.
However, I could not get the option to enable.
What is correct? I don't want to needlessly upgrade the database since it is well within the size limits of Express and the upgrade to full SQL Server is very expensive and will add unnecessary complexity.
