Server rental is needed for hosting websites, databases, corporate services, CRM systems, and other online projects. VPS/VDS and dedicated servers allow for flexible infrastructure configuration and handling high loads, but stable server operation requires regular monitoring of system status.
One of the most important aspects of administration remains monitoring load and data backup. These help to timely identify problems, control resource usage, and reduce the risk of data loss.
In this article, we will discuss the basic principles of server monitoring, data backup, and recommendations that will help enhance the stability and security of server infrastructure.
Why it is important to know the regulations for working with the server and adhere to them
Recently, one of the clients faced a serious problem: two disks failed simultaneously on the rented server. Since backups were also stored on the same server, all data was lost as a result. In many years of operation, this was a rare case, but it clearly demonstrated how important it is to properly organize backups and monitor the state of server infrastructure.
During server rental, the client gains full control over the system, including root access. Along with this, they bear the responsibility for data security, software status, and timely response to potential issues.
In this case, the cause of the incident was the physical wear of the drives, which could not be detected in time. Regular checking of SMART indicators, monitoring of the RAID array, and timely replacement of components could have helped avoid data loss.
It is important to consider that the provider's technical support does not have access to VPS/VDS or the client's dedicated server without an additional order for administration services. Therefore, the server owner must independently monitor the system's operation or use administration and monitoring services.

Why it is important to create multiple backups of data
Regular backups are not enough if they are stored on the same server where the main data is located. In the event of hardware failure, RAID array damage, or simultaneous failure of multiple drives, both working files and the backups themselves can be lost.
That is why backup should involve storing copies of data on different media or servers. One of the basic recommendations is the 3-2-1 rule:
- store at least three copies of data;
- use at least two different media;
- keep one copy separate from the main server — for example, in another data center or cloud storage.
Many providers additionally offer separate space for storing backups. This enhances data security and reduces the risk of loss in case of problems with the main server.
At the same time, the responsibility for creating, configuring, and checking backups usually falls on the server user. Therefore, it is important to regularly check the functionality of backup systems and the ability to restore data in case of emergencies.
It is also worth clarifying with the provider whether additional backup services, storage of backups on separate servers, or automated infrastructure monitoring are available.
Do not skimp on data security
To enhance the fault tolerance of server infrastructure, it is often recommended to rent a server with two drives configured in RAID 1 (mirrored RAID array). In such a configuration, data is written simultaneously to both disks, allowing the system to continue operating even if one drive fails.
However, some users forego RAID for the sake of greater disk space. This approach allows for the full capacity of the drives to be utilized, but increases the risk of data loss during hardware failures or physical wear of the disk.
It is important to consider that RAID does not replace backups but only enhances the server's resilience to failures of individual components. Therefore, when configuring the server, it is essential to consider not only the available storage capacity but also the level of data protection.
If necessary, it is also advisable to consult with the provider's technical support regarding the optimal configuration of the server, backups, and additional data protection tools.
Server administration services
Administration services may vary in the level of support and the range of available tasks. The choice of a specific option depends on the user's experience, project complexity, and the need for constant monitoring of server infrastructure.
If the user does not have sufficient administration experience, time for regular system monitoring, or the ability to respond to technical issues independently, it is worth considering additional administration and monitoring services.
Hourly administration
This format is suitable for users who primarily manage the server themselves but occasionally need assistance from specialists. Hourly administration may include password resets, website migrations, PHP configuration, SSL certificate installation, software updates, backup configuration, and other technical tasks.
Full administration
With full administration, the server is under constant monitoring by specialists. Such services may include software installation and configuration, load monitoring, backups, security updates, and prompt response to failures or incidents.
Load monitoring
Separately, providers may offer server load monitoring services. In this case, the system monitors the status of the main server components — CPU, RAM, disk subsystem, and network — and notifies the client of any exceeded thresholds or potential issues.
When choosing administration services, it is important to consider the level of responsibility that the client is willing to take on. For business-critical services or complex infrastructures, professional support helps reduce the risk of downtime, data loss, and security issues.
