does "Waiting for completion" state of writers effect the backups ?

Except reboot, what can be done to fix it.

Waiting for completion means there is still a backup running VSS wise.

Some of the writers can be reset by restarting the relevant services

There is a list of some of them here:

http://www.planetcobalt.net/sdb/vss_writers.shtml

In this case the issue seems to be with the IIS, an unfinished config of IIS can cause this the problem seen here.

The standard questions: Have you checked: 1) What has changed. 2) The manual 3) If there are any tech notes or VOX posts regarding the issue
