We recently had a problem where the system (C:) drive of a Windows Server 2012 VM got hosed by an update.
Unfortunately we did not know about the problem until a reboot which happened long enough after the update that it transpired that all backups had the same problem.
This was not catastrophic as the data drives were fine and so we just attached them to a different server.
The big problem that we did have was that this was a file server and in losing the system, we also lost:-
1. The configuration of all the file shares on this server (there were a lot)
2. Detail of all the scheduled tasks on this server
So even though the shared data and associated file permissions remained, we had to rebuild all the file shares and this has taken a long time (and we are still discovering things that we missed).
So - I am wondering if there is an easy way to backup this configuration data in some other way so that it could be easily restored in the future if this happened again?
I am looking for something in addition to a standard backup, so even if the C: drive was corrupt on every backup instance, we could still restore this information using some other method.
The suggestion of keeping backups for longer is a valid one, however this is a server on an IaaS platform and it is not cost effective to keep backups for any longer than 2 weeks.
How do other people do this? Anyone got any ideas?
