Backup Fails with Error C is invalid drive
It looks that one of my server is facing problem with backup. It was working fine. The backup is configured to store all data in the C drive. Later on I went in the log and find that the backup files. It showed that C drive is not a valid drive. It looks like someone has played with the file permission. To fix the problem I tried to do the same using a hotfix provided in KB817688. But still it is not working. I got a new error related to unpdate.ini file.

Yes it a permission issue. You will need to reconfigure the backup again. It looks some recent updates or software installation has cause the bug. It is recommended that you must try to run a system restore to get some old settings back. I am sure it will work. But if still it is not working then go in error log and find out more information on it. Can you find any service which is associated with the problem.

It is better if you can provide more detail on the same. The backup if failed you will need to check the space also. Sometime if you have low space then you face this kind of bugs. Check that what type of backup you had select. A number of old backup files are overwritten and new backup file takes its place. But if you had not selected the options the backup will be created again and again causing complete packup of disk size.

Where is the backup media. Means where are you saving the backup. Is it a internal partition, a removable driver or network location. There are some updates that can help you. You can try hotfix 817688. This hot fix allow you to manage error related to data write on media. Run the updates once again and check back. If still you get the problem then you can try to download the updates manually and install it. Reconfiguring updates from scratch is another way to fix the problem.
