The SharePoint services writer is waiting for completion.  Did you install any SharePoint updates lately?  (It could be due to the Sharepoint SP 1). If this is installed, then you need to fix SharePoint before your backup will work.

1. Open an Administrative command prompt.
2. Change directory to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN
3. Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures

Try to run a backup after running this command. Exceptionally the server might be needed a restart otherwise we are good to after running this command.

    Also check the state of the writers by running the following command in command prompt from system32 prompt.
    Start > Run > cmd
    cd windows\system32
    vssadmin list writers

    Check the state of the writers. If any of them is in a failed state then do the following.
    Start > Run > regedit
    Goto HKLM/Software/Microsoft/EventSystem/{26c…./Subscriptions.
    Backup and delete the above registry key.
    Reboot the server.

    Also make sure that the c:\windows\system32\volsnap.sys driver is updated.
    This is the updated one :

    Good Luck !!
