I have a database, about 7GB, that I am attempting to backu pacross the network to a Firewire drive connected to another server. The bakcup runs and seems to be complete, but ends with an error. When I check the SQL Server log the error is:
BackupDiskFile::RequestDurableMedia: failure on backup device '\\cherry\dumps\mole\molert_full.BAK'. Operating system error 87(The parameter is incorrect.).
I have googled the error and have not found anything that is of any help. Most of the hits are just MS error code listings. Does anyone know anything about this Operating System Error?
I am successfully using htis backup strategy at another location.
There are no errors in the Event Logs other than the failure due to OS Error 87. IT is interesting that in the other location where we are using this solution we are experiencing the same problem now after applying the latest Windows Updates. Since it happened at the end of our day we put a short-term fix in and will be working on it tomorrow. We will probably roll back the updates applied today one at a time and see which one may have caused the problem. I will post what we find out.
If anyone else has seen this problem please let me know what you did to correct it.
I've the same problem. Backing up around 20 DB's the same way. Only master or msdb fails with that error message all others with success. I verified the backup, everthing is all right.
