A server backup is a proactive process of creating duplicate copies of critical data stored on a server or networked computer system. These duplicate copies, known as backups, are stored separately from the original data source, ensuring their availability even if the primary data becomes compromised, corrupted, or lost due to various factors such as hardware failures, human error, cyberattacks, or natural disasters.
Server backups can encompass various types of data, ranging from entire server images to specific files and folders. The choice of what to back up and how often depends on the specific needs and priorities of the organization or individual.
Server backup solutions come in various forms, including local backups and cloud backups, each with its advantages and considerations. Moreover, the frequency of backups can vary, with options such as daily, hourly, or even real-time continuous backups to ensure that data is as up-to-date as possible.
In this article, we will unravel the concept of server backup, understand what it entails, and realize the invaluable benefits it brings in safeguarding your data against such alarming scenarios.
Why are server backups important?
Despite the integral role that backup solutions play in modern data protection, recent statistics paint a concerning picture: 14% of all data is not backed up at all, and a staggering 58% of recovery attempts fail.
These figures highlight a critical gap in data security, leaving businesses’ most valuable assets exposed and at risk of being lost forever in the event of an outage or cyberattack.
Here are the primary reasons highlighting the paramount importance of server backups:
1. Data preservation

Types of data backups
Data backup strategies encompass various methods to cater to diverse needs and scenarios. These different types of data backups provide flexibility and options for preserving data efficiently. Some of the most common types include full backups, incremental backups, differential backups, and mirror backups.
1. Full backup
A full backup, also known as a level 0 backup, involves copying all the data in a system or specific storage location to a backup destination. It creates an exact replica of the entire dataset, making it the most comprehensive and time-consuming backup method. Full backups serve as a foundation for other backup strategies.
2. Incremental backup
Incremental backups focus on capturing changes made to data since the last backup. Initially, a full backup is performed, and subsequent backups only record new or modified files.
This approach conserves storage space and reduces backup time. However, the restoration process requires the full backup and all incremental backups since that point, which can be time-consuming.
3. Differential backup
Differential backups, like incremental backups, start with a full backup. However, they capture all changes made since the last full backup, regardless of how many differential backups have occurred in the interim. This simplifies the restoration process compared to incremental backups but requires more storage space over time.
4. Mirror backup
A mirror backup, also known as a 1:1 backup or a real-time backup, duplicates data in real time to a separate storage device or location. This method provides immediate redundancy and can be crucial for minimizing data loss in high-availability environments. However, it can be resource-intensive and costly due to the constant data synchronization.
5. Snapshot backup
Snapshot backups capture a point-in-time image of data, creating a read-only copy of the entire dataset. These snapshots are lightweight and don’t consume as much storage space as full backups. They are particularly useful for creating consistent copies of data for development, testing, or data analysis purposes — but they’re not so helpful for full data recovery in case of a major loss event.
6. Continuous data protection (CDP)
Continuous data protection (CDP) is an advanced backup method that captures every change made to data in real time or at short intervals, allowing for granular recovery. It offers near-zero recovery point objectives (RPOs), ensuring minimal data loss during restoration. CDP solutions are often used in mission-critical applications where data integrity and availability are paramount.
Local backup vs. cloud backup

The importance of offline backups
Offline backups, also known as cold backups or offline data archives, involve storing copies of your data in a location that is disconnected from the network and not constantly accessible. This practice serves as a critical safeguard against various data loss scenarios. Here’s why it’s so important:
Protection against cyberattacks
Cyberattacks, such as ransomware, are becoming increasingly sophisticated and can easily target and encrypt data stored on connected devices or NAS. Offline backups, being physically disconnected from the network, are immune to such attacks.
In the event of a ransomware attack, having offline backups ensures that you have clean, uninfected copies of your data to restore from.
Preventing accidental deletion and corruption
Human errors, software bugs, or system glitches can result in the accidental deletion or corruption of data. If your backups are constantly connected to the network or live on the same system, these errors can propagate to your backup copies.
Offline backups, on the other hand, provide a static and protected snapshot of your data, reducing the risk of such errors affecting your backup.
Natural disasters and physical damage
Physical threats like fires, floods, or hardware failures can lead to the destruction of your primary data and any online backups stored in the same location.
Offline backups, stored in a physically separate and secure location, act as a disaster recovery mechanism. They remain unaffected by local catastrophes, ensuring data availability even in the face of such events.
Long-term data retention
Some data needs to be retained for extended periods, often for compliance or historical reasons. Offline backups offer a cost-effective solution for archiving data for the long term. These backups can be stored on offline media like tape drives, which are well-suited for preserving data over extended periods.
Reduced dependency on internet connectivity
Online backups often require a robust and continuous internet connection for data synchronization and accessibility. In situations where the internet is slow, unreliable, or unavailable, offline backups provide a reliable fallback for data retrieval and restoration.
Enhanced data privacy and compliance
In industries with strict data privacy and compliance regulations, offline backups can help maintain data sovereignty and security. By keeping sensitive data offline, organizations can better control access and protect it from unauthorized breaches.
