I have recently started working with AlwaysOn availability groups. The suggested method to deal with users in AlwaysOn groups is with partially contained databases, then the user is in the DB only, which is replicated to all nodes. However, there are some situations where you cant make a DB a contained DB. One of the […]
I recently had the task to do a DR restore several SQL databases using RedGate backup software. The software is incredible and does things very well, but I had to restore 3 servers each with dozens of databases – not something to be done by hand. Here are a few tricks I learned during the […]

This is compounded by the fact that the new server is 64bit OS and SQL, where the original was 32bit. For posterity, […]
I got alerted over the weekend to a SQL server running out of disk space on one of its drives. Upon further inspection, several of the LOG files had grown and were filling the log drive. I went to shrink the files, but realized there must be a better way. A little googling and I […]
