Best practices are patterns that have proven themselves over and over again as a way to achieve a high quality of your solutions, and it’s completely irrelevant who proposed them.
Tough to say isn’t it ?
Here’s the things to think about though .
- Backups … It helps backup scenarios…if they are separate. It’ll be cheaper and quicker to back-up the “C” drive with no logs on it. You don’t necessarily need to back up logs. Less data is quicker, easier to store.
- Speed impact.. What are you logging, everything, or just minimal. If everything and on a busy Farm, you probably need to keep it away from the OS drive. (less I/O)
- Security / Access . Do you want people to access your OS Drive to look at logs. What if they delete the wrong folder ? Do you want shares from C ?
I can’t see why you wouldn’t log to a separate drive if you have one. Best practice ? Don’t know. I will leave it you Admins!
