I did set up SQL Server managed backup for our databases. I did define retention days to 4, but i just checked the azure storage account where the managed backups are and found that there is still all the files from the day i did set up managed backup (2015/12/1).
SQL i used on every user database:
We are using SQL Server 2014 Enterprise with Azure VM.
Set up tutorials and information about the managed backups: MSDN
Is SQL server managed backup to Azure supposed to automatically delete backups after given retention days have passed or do i need to implement custom job for that?
