When we apply a CU or service pack to our instances of SQL Server, (2012, 2016 and 2017), we then stop the Sql Server and agent services, zip up the system databases and the mssqlsystemresource database and place them in a folder on the C drive. The normal database backups, which includes system databases, occurs around 8pm. After this, these files are copied over by a network backup process to another location. The C drive is also backed up a this point.
The zipping up and storing the system and resource database in a C drive folder is that that we have a quick bare metal restore option.
This process is something that I have inherited and it seems an unnecessary process, or am I missing something?
Any thoughts on this would be appreciated.
