How can I improve off-site copy performance via FTP?
Is there any "undocumented" tuning feature or is any RFE required to achive that?
SSR 2013 Desktop Edition is running on Windows 7 and off-site copy is sent to a remote server via FTP.
The hosts are connected through 10Gb ethernet.
Transfer rate of FTP protocol between the host is 300MB/s or more.
It is an actual rate when I tested to send SSR backup images to the remote server using a bundle ftp command of Windows 7.
However, off-site copy performance is up to around 100MB/s under the same environment. The both hosts are not so busy.
Almost 10% of network workload and 30% of disk I/O workload during the off-site copy. Much CPU/Memory resources are free.
The admin guide never describes any feature or tunables to improve the FTP performance.
I opened a Symantec case and asked about that. But the answer was "no such feature is available".
I wonder if any "undocumented" feature or tunables are implemented on SSR 2013.
Or performance improvement on FTP off-site copy will be provided by a patch or in the next release.
Any advice or information?
No useful data is obtained in the meanwhile probably because of off-site copy operations with small sized data due to incremental backup. One of full backup tasks is scheduled in this weekend with large sized data transfer. Please give me a few days for next feedback.
