SBS 2008 Backups fail with unknown error.
// May 20th, 2010 // Uncategorized
I can’t stand stupid issues and an unknown VSS error to me is stupid. So when my backups were failing constantly I needed to figure it out. I narrowed the issue down to the SQL VSS Writer but even registering all the DLLs again didn’t fix the problem. I finally figured it out. I had moved my SharePoint Services databases to a different directory and the Network Service didn’t have rights to the directory. I added full control for the Network Service and now backups are flying through with no problem. I really wish an unknown error would be defined!
