Reinstalling server

Hi,

Due to some Windows issue, can't clean-up the WinSxS folder and the Disk Space process (cleanmgr.exe) makes the CPU going to 100% meaning that I am at 97% of disk usage, I am planning to reinstall the server where my SQL engine is running.

I know I have to backup the databases, fine with that. How do I backup the login and their rights ? I have got also some jobs I would like to backup. Anything else I should think of ? Should I backup and restore the master db or any other system databases ?

Consider I have got 72 databases and 85 logins so I wouldn't want to do that one x one.

My server is a Windows Server 2016 running a SQL Server 2016.

The reinstallation of the OS and SQL Server engine will be done for me by my provider.

can you set this all up on another server and move it to new server? Might be easiest. Also, there is a proc called sp_help_revlogin that's floating around that can help with the logins, especially the SQL Logins. I'll post it here

Nope, it will be on the same hardware.

For the logins I found this dbatools docs | Export-DbaLogin

For the jobs, scheduled tasks I found out how to export them

Also any possibility you can add beefier new disk and move your ldf, mdf there. your approach with so many databases seems tough and fraught with landmines.

detach, move, re-attach. could also be done via powershell etc
