Outgoing synchronization and encryption of process files

Recently, the PLM project is coming to an end, and documents need to be sent out after completing the process within the data R & D department. This article mainly explains how to solve the timeliness and security problems of outgoing documents. I hope you can give me some advice:

Question:

1, data independence of data R & D department 2, data independence between suppliers 3. After the process, encrypted data needs to be downloaded by suppliers to meet procurement needs.

As shown in the figure:

Solution:

1. FTP build (ftp) 2, web file management service set up supplier user and sponsor user (seafile file) 3, automatic data synchronization software installation (windows group policy) 4, external network access (nat mapping intranet)

1:ftp build here not to say much about the evening tutorials, instructions: PLM project needs (preferences to configure outgoing file address, that is, ftp server address)

2: install seafile (https://manual-cn.seafile.com/deploy/https_with_nginx.html)

Client installation and administrator account login

A: configure initiator account b: configure vendor account c: configure data folder for each vendor

3:freefilesync+windows task settings

A:freefilesync can refer to https://blog.51cto.com/yangeinstein/2056993 to configure the synchronization path according to your actual business.

B:widnows task settings:

The trigger condition is automatic every 5 minutes (will not be turned off automatically, and a process will be generated every 5 minutes)

Trigger the shutdown (freefilesync) process to prevent the server from panicking

4:30 per hour using dos taskkill / im process name

4: firewall nat private network mapping, so that the external network can be accessed
