So, I upgraded to Win7 Professional specifically to use the network backup feature. (Thank you student discount!) However I have having two errors, so far, no successful backups.
1: Unable to create shadow copy could not be created. Please check "VSS" and "SPP" application event logs for more information. Details: insufficient storage available to create either the shadow copy storage file or other shadow copy data. (0x81000019)
Hmm, I don't think it is a storage issue. I only have about 320GB of files on my entire drive, and an entire 1TB open on this backup drive. I've looked into the VSS and SPP services and they both appear to be running so I am not sure what would be up with them.
Well... I ended up going for custom settings and turned off the shadow copy in the back up options and then attempted the back up again. And I get a classic "Access is Denied" error.
