First, database services
After the long-term operation of the database, it is necessary to adjust the performance of the database and make it enter the optimal state. The data in the database is extremely important, and if these databases are lost, the loss is huge, so it is necessary to backup the database regularly, just in case.
2. Maintenance of the operating system
The operating system is the software foundation on which the server runs, and its importance is self-evident. Most Server operating systems use Windows 2012R2 or Windows 2016 Server as the operating system, which is relatively easy to maintain.
Open the event Viewer and look in the system logs, security logs, and application logs for any unusual records. Now there are more and more hackers on the Internet, so it is necessary to download the Service Pack(upgrade service pack) on the Microsoft website to install the security holes in time.
3. User data
After frequent use, the server may store a large amount of data. This data is a very valuable resource, so it needs to be organized and backed up so that even if the server fails, the data can be recovered.
4. Maintenance of network services
There are many network services, such as WWW service, DNS service, DHCP service, SMTP service, FTP service, etc., as the server provides more and more services, the system is also easy to chaos, at this time may need to reset the parameters of each service, so that it can operate normally.
