Backup over the network

Feb 17 at 9:16 AM
I creating a backup software in c# for my organizations.
I have a problem with time to do a backup of my workstation to a shared folder on a server.
If i direct compress the files to the shared folder with temp file created direct to the shared folder, the time to compress is 3 minutes, but if i set the temp dir on the workstation, the compress time is 2minutes.

I test this job with another backup program and the backup process with temp file created direct to the shared folder is 2 minutes.

What is wrong with dotnetzip ?
