Re: Backup exec 2014-Tape backup is too slow, spend too much time before the IO running.Hi VJware, Thank you for your advise. After disable the function, performance enhanced a little, but still slow. 2 job (5G each) used 15min; 10 job (5G each) used 1 hour. It now spend too much time on "Queued" stage. (no other jobs and no alert) Do you have other method to enhance the performance?Re: Backup exec 2014-Tape backup is too slow, spend too much time before the IO running. Hi CraigV, Thank you for your quickly repley. The following is picked in tech doc. There is no need to install tapeinste.exe in windows 2012R2. "Note: You do not need to install Symantec tape device drivers if Backup Exec runs on Windows Server 2012 and later. Symantec kernel-mode drivers and tapeinste.exe are no longer installed if Backup Exec runs on Windows Server 2012 and later."
