Multiple protection solutions for school data

    Foreword

    The ease of use of the Synology DSM operating system reduces the technical barriers to NAS usage and maintenance. For a diverse application experience, the network monitoring and setup of video surveillance is surprisingly simple.


    Organization Background

    A school tram team is a college student electric formula racing team. The team independently designs and manufactures a college student electric formula car and participates in the college students' electric equation series. Since the team was officially established in March 2013, the pursuit of speed and efficiency and the attention to the environment have brought together more than 150 DIAN Racer with international vision and innovative thinking. The team members are united and enthusiastic. The team has grown from scratch, and now it has begun to take shape, laying a solid foundation for becoming a high-level, international fleet.


    The 2016 season was the third time that a school tram team participated in the China competition. It won the first place in the best overall power score, the second in efficiency test, the third in racing design, the third in durability, and the second prize in speed racing engineers. The total score of the country's third and national first prizes.

     


    Challenges facing

    As the self-managed racing team of the students, the team will be the core member of each subsystem, and the ordinary team members will assist them in the design. From the management structure, they will be divided into the team leader, the team leader and the team members. The two identities are in parallel with the team core. Many aspects of technology create difficulties in rights management. This is the core management problem of a school's electric car team. In general, the racing team that the students manage themselves mainly faces the following management and operation and maintenance problems:

    In the design stage of the car, the overall assembly digital model of the car will maintain a high frequency update, and the various components on the car will be iterated several times. The design documents are very important in the record design process and as the training of new team members. How to be systematic and convenient The backup design files have always been a big problem for the team.

    In order to strengthen fleet management and coordinate the design of the car, the team often needs to count the whole car parts, statistical processing and progress. There are always documents and forms that need to be collected from multiple players, and then aggregated into a master list, the time of collection and summary. Waste is a profound pain point.

    When designing work in the team studio, the uploading time for large files by e-mail between computers is very long. There is no way to store them on the server through storage media such as U disk. It is inconvenient to not operate the mobile phone next to the computer. Retrieving.

    Team members often carry out composite material processing and circuit board soldering and wiring in the studio. The recording and retrieval of work processes, as well as the training and troubleshooting of new members, have been difficult to solve.

    Due to the large-scale rework caused by disk damage, we have been sensitive to the issue of ensuring data security. Key files that do not want to affect the progress of the project are lost.


    Solutions

    According to the current management pain points of the team, the Synology DS916+ was selected and 8GB of memory was used. At the same time, it was equipped with Seagate IronWolf Cool Wolf hard disk. In addition, two surveillance cameras were set up to monitor the team studio in real time and understand the progress of the work. In addition, it can also ensure the environmental safety of the team and the unified storage of tools.

    Multiple protection of data: backup, monitoring and redundancy


    The backup tools provided by Synology's own DSM operating system can greatly reduce the risk of viruses and quickly respond to ransomware and protect all data of the fleet. By using Cloud Station Backup, the fleet automatically backs up all the data on the computer, and the multi-version backup of Cloud Station Backup can also restore the files to the specified historical version, which greatly saves the collection of historical versions and the team's unified update assembly model. time consumed.


    Of course, the mechanical loss of the hard disk and the resulting data loss are the most worrying issues for the team. For this reason, the team chose Seagate IronWolf Cool Wolf hard drive, and the Synology DSM 6.1 can use the hard disk health management tool - IHM to help the team more timely. Found a hard drive problem. Data redundancy is also protected by setting the RAID array.


    Permission settings and multi-sector online collaboration in the team

    Before adopting the storage solution of Synology, a school electric train team often confused the management of the rights between the team management personnel, the subsystem heads, and the team members. It also affected the efficiency of the work because of the data aggregation of the various departments. For these two questions:


    Permission settings: User group resolves the duality of identity

    By using the user group function of the DSM system, the duality problem of the player's identity is solved. For the players who are both the core player (group A) and the team leader (group B), cross-administration can be implemented through the group, for example, viewing each group. Task documentation, work progress, or view confidential documents that only core personnel can read and write.


    Teamwork: A set of online Office suites that link all user data

    A very simple task - to calculate the quality of all the parts on the car, in the past may require all relevant players to complete one by one, and then arrange a special person to summarize. The Office suite in the Synology DSM suite makes tasks simpler—all team members complete the data directly in shared documents and tables. When the last team member fills in the data, the quality statistics table is complete. And the files of the Synology Office suite remain local and do not pass through a third-party server, which can effectively protect the privacy of many sensitive data.



    

     


    Convenient shared file management and transfer

    There are two main aspects of the team's large files: video and digital model files. For video, it is mainly watched online using Video Station and does not need to be downloaded to a personal computer. For larger digital-to-analog files, File Staion and network drive mapping can directly use the shared folder as a computer hard disk, so that you can retrieve the data on the NAS at any time.


    In the absence of a studio, the need to access the NAS in the bedroom or library is limited by the limitations of the campus network topology. The team can easily access the NAS in the external network environment by using the Quickconnect service. A case where a storage medium such as a USB flash drive is required.


    


    Simple, friendly video surveillance

    The rapid response and playback function of Surveillance Station also impressed the team. It is not only capable of file access and video recording for video surveillance, but also more convenient for online viewing and downloading according to time period. It solves the pain points of finding a few hours to find the required materials, and reduces the pressure on the hard disk of the video production team. It only needs to download the required clips, and the interaction design is very user-friendly.


    Results

    Compared with the network disk used by a certain school electric car team, especially in the local network, the upload speed and download speed are significantly improved, and basically can reach the limit speed of the player's notebook network card. Moreover, for the sensitive information of the new design and fund usage of the season, there is no need to worry about the risk of privacy leakage stored on the third-party server, and the security is greatly improved. IHM is also a good way to reduce the risk of storage media problems with disk array RAID and hard disk health management.


    Other functions such as support for automatic shutdown, support for fan sound adjustment, support for scheduled tasks, and convenient settings in the control panel allow a school tram team to feel the people-oriented software of the Synology NAS products at the software level, just taking into account the users. Demand.


    Compared with other NAS products, the ease of use of Synology's DSM system has become the main reason why a school electric team chose it. The DSM system makes the use and management of the NAS as intuitive and simple as possible through reasonable and concise planning and design. This interactive experience that is very close to the mobile phone is very smooth in use, and for the team members who are not network management, It is also very friendly to use. These are popular with ordinary users on NAS-sounding "very professional" products.
