WHO AM I ?
My name is Aamir Syed and I run SQLEvo. I optimize the speed, efficiency, and stability of SQL Server. When not working I like to lift weights, play music, and travel with my wife.
Does SQL Server need more memory? Page Life Expectancy
Page Life Expectancy is the number of seconds the average page of data has been in the buffer pool.SQL server keeps data pages in memory for quicker access instead of having to read from disk every time. Now, keep in mind that Page Life Expectancy doesn’t prove or disprove anything on its own. It’s simply a symptom of potential memory pressure. If you think that your server is suffering from some sort of memory pressure, this is just one piece of a bigger puzzle that can help
No Backups, No Logs, No Dice...
It's becoming less surprising, but no less scary when I find shops not taking regular database backups. This happens quite often in situations where there is no dedicated DBA. Meaning someone else just kind of took over those responsibilities ("accidental DBA", if you will). Why can't I just include the .mdf and .ldf files in a system wide backup? Some of the common explanations I get is that "Well we run a file system backup, so the database files are backed up". Unfortunat
Backup Encryption
If you're storing any of your database backups off site or in the cloud, you might want to look into encrypting your backups. This feature was first introduced in SQL 2014. Since we're working with encryption on SQL server the first step is to create a Database Master key. Then we create a certificate. Then run your backups with the correct syntax and specify the algorithm you'd like to use (AES 256,128, 192 or Triple_DES_3Key). #sqlserver #backups #DBA #Encryption
