The Solution Rating System
|
|
| With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating. - The Grade of the Solution
- The Zone Rank of the Expert Providing the Solution
- The Number of Author and Expert Comments
- The Number of Experts Contributing
- The Feedback of the Community
Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site. If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support. Thank you! |

Asked by tomfogarty in Powershell, Microsoft Operating Systems, Windows Server 2008
I'm trying to run WBADMIN via a PS script. I'm generating the commandline with variables. The script is designed to perform a backup (obviously as a scheduled task every night) to a different location which is created depending on the date and time that the script is called. Code below.
When I run this as a script "powershell -command .\backup.ps1" I get the following error from WBADMIN:
"ERROR - The value for option: backuptarget is missing. See usage below."
The problem I'm having is that the parameters for WBADMIN require "-" which it seems to me is throwing the call to WBADMIN from powershell.
I've tried a lot of things to ascerrtain what exactly is causing the problem. I'm certain it's the hyphens (obviously because they form a vital part of PS syntax). Is there a built in way around this or can anybody recommeny anything or is it something really stupid I'm doing wrong.
Thanks.
Tom.
