Well here we are again, after another disastrous Friday I found myself in that difficult situation where 2 failed disks in one array caused one of my servers to crash. The disks that failed were the ones that had the OS (operating system) on them.
2 failed disks in a 4 disk array that had the operating system on it.
Replaced the failed disks and re-create the array and logical drive and restore the OS back onto the disks.
I discovered that only the data disks were being backed up and not the system disk.
**45 second PANIC**
Replace the failed disks, re-install the same operating system (Windows Server 2003) and get the shares back (if you have some record of the shares on the server in question)
It all sounds good in theory but it wasn’t plain sailing. The server rebuild took the whole day (including backup software install, AV software and security updates. The process was long and laborious but it did highlight some areas that we all could learn from – check your backups…. do an inventory of all your systems, check that each drive is part of a backup plan and confirm that theses backups are running. I can’t stress this enough.
Check your backup plan, schedule and systems.
- Get a full list of all your servers.
- Log into each server and get a list of all the drives on each server.
- Check that each of the drives is part of a backup schedule
- Confirm that these backup schedules run regularly and successfully
- Document the process
- Set a reminder for every 3 months to check the list and confirm that everything is being backed up.
That was a very long Friday…
