Backup and Disaster recovery same but different!

Data plays an integral role in the modern digital landscape, influencing businesses and their operations. While protecting this precious data is crucial, there often arises confusion regarding the terminologies used for its protection, primarily Backup and Disaster Recovery.

The Misconception

Misunderstandings exist regarding backup and disaster recovery, which are distinct functions. Backup involves replicating original files, while disaster recovery involves recovering the entire IT infrastructure by keeping its copy off-site. While they may be considered the same in some functions, they are distinct.

Backup Explained

It’s common for organizations to back up data, but what does this mean? At its essence, backup is simply creating a copy of the original files. This means that if a file gets deleted or corrupted, you can retrieve a version from before the mishap occurred.

Backup and Disaster Recovery

Backups are particularly handy when you need immediate access to a document that was previously saved or when a single file goes missing. They can be performed daily and generally focus on data retention at a singular location, keeping the process relatively straightforward.

Disaster Recovery Delved Into

Disaster recovery simplifies IT infrastructure maintenance by preserving off-site servers, software, and data configuration, ensuring continuity in network outages or security breaches. It enables businesses to switch to alternative environments, reducing data backup and configuration burden.

Disaster recovery is a broad strategy demanding meticulous planning. It involves tasks like setting up a recovery protocol, identifying mission-critical systems, establishing communication processes, and designing steps for effective recovery.

The recovery time objective (RTO) is a crucial aspect of planning, determining the time it takes to restore off-site IT systems. It involves replicating the entire IT infrastructure at a secondary location, requiring an external production environment for accurate data replication.

Ideastack emphasizes understanding these nuances to provide clients with tailored solutions.

Frequently Asked Questions

Q1. Isn't having a backup enough for my business?

While backups are essential, they’re limited in scope. They’re perfect for retrieving individual files but won’t help if your entire IT infrastructure faces a threat. For comprehensive protection, a Disaster recovery plan is imperative.

Q2. How do I know if my disaster recovery plan is effective?

Regular testing is the key. By simulating disaster scenarios and practicing the recovery process, you can gauge the effectiveness of your DR plan and make necessary adjustments.

Q3.What's the difference between RTO and RPO (Recovery Point Objective)?

RTO is the time it takes to restore operations after an outage, while RPO determines the acceptable amount of data loss measured in time. Both are crucial metrics in Disaster Recovery planning, helping businesses align their recovery strategies with operational needs.

Back up that is based on Host

In a digital era dominated by vast amounts of data, protecting that data has become paramount. Enter host-based backup, an innovative solution at the forefront of data recovery. But what exactly is it? Let’s dive in.

Deciphering Host-Based Backup

Deciphering Host-Based Backup

Fundamentally host-based backup, often termed Agentless Backup and Agent-based Backup, is a modern approach to ensuring data integrity and security. By definition, it revolves around a server, the host, that is paramount for backup processes.

The Agent Paradigm

Before delving deeper, it’s crucial to clarify the term “agent”. In the IT realm, agents are small applications stationed on the host server, which execute particular functions methodically.

Agentless vs. Agent-based Backup: What’s the Buzz About?

Some vendors might claim their backup solution is agentless. However, they might incorporate an agent initially and eliminate it after completing the backup process. Although this might seem agentless, it technically isn’t.

Agentless Backup

A backup process that does not involve agents. It’s straightforward, with no additional software or processes interfering during the backup.

Agent-based Backup

This approach utilizes one or multiple agents, or applications, to backup data. A significant step for this backup type requires the system to reboot post-installation because of the snapshot driver’s location in the operating system kernel.

Choosing Between The Two

When deciding between agentless and agent-based backups, it’s crucial to understand the pros and cons of each.

Agentless Backup

Provides enhanced host system control and visibility. Resides with the OS stack. Provides advantages like Change Block Tracking (CBT) at the kernel level, simplifying the process.

Agent-based Backup

No need for additional software installation, leading to potentially smoother operations. Requires file system traversal for determining changes for backups, which could be more time-intensive.

Deep Dive into the Backup Mechanism

Every scheduled backup employs Delta Encoding deltas, which are sent to a backup archive. This action efficiently creates a virtual Disk Image. With Continuous Data Protection, you can restore these disk images to another disk, replicating the original disk’s structure and contents seamlessly. Moreover, individual files within a disk image can be reinstated either to their original location or another system.

R1 Soft Server Backup Manager

The R1 Soft Server Backup Manager is a near-continuous backup software compatible with both Windows and Linux systems. This tool allows for user-scheduled near-continuous disk-based online backups for multiple servers, ensuring data remains protected and easily recoverable.

Agentless vs. Agent-based Host-Based Backup


Host-based backup is not just another tech buzzword – it’s a tangible solution driving the future of data recovery. In an age where data loss can spell disaster for businesses, adopting efficient and effective backup solutions is no longer optional. Whether you lean towards agent-based or agentless backup, the key is to understand your needs and choose accordingly. With industry leaders like Ideastack providing top-notch backup solutions, the data landscape looks more secure than ever.

Frequently Asked Questions

Q1. What is the primary difference between host-based backups and traditional backups?

Host-based backups focus specifically on data stored on host servers, often employing agents for the backup process. Traditional backups might involve copying data from various sources, not just host servers, and may not utilize agents.

Q2. Are host-based backups suitable for all types of businesses?

While host-based backups offer advanced features beneficial for many businesses, their suitability depends on the specific data recovery needs and IT infrastructure of a company.

Q3. How often should I schedule my host-based backups?

The frequency depends on the volume of data changes and the critical nature of the data. For vital systems, near-continuous backups might be preferred, while less critical systems might only require daily or weekly backups.

Backing Up Defenses against DDOS Attacks

Examples of legitimate tools used are helping, socket programming, and httping. There are also underground tools available for such attacks.

DDoS stands for Distributed Denial of Service. DDoS is a DOS attack where multiple compromised systems, often infected with a Trojan, target a single system causing a Denial of Service (DoS) attack. This kind of attack tries to make a computer resource unavailable to users.

DDOS attacks

Signs of a DDoS attack

• The US Computer Emergency Response Team defines symptoms of a DDoS attack as.

• Unusually slow network performance, either processes or opening files. Unavailability of a website.

• Inability to access a website. The dramatic increase in spam emails; this is an email bomb.

• DDoS attacks lead to issues with branches of a network being attacked. The attack overloads the network; other branches will try to compensate for the increase in traffic.

• This causes the whole network to slow down. A large enough attack can shut down entire regions of internet connectivity.

The DDoS attack may also use malware to cause further damage.

• Max out the processor’s usage so no work gets done

• Cause Microcode errors in the machine

• Lock up the computer by giving the processor erroneous sequencing

• Crashing the operating system itself.

Defending against DDoS attacks

• Recognize the signs of a DDoS attack. The first and best defence against a DDoS attack is recognising it early. Unfortunately, not all DDoS attacks are easy to distinguish from normal spikes in the network or web traffic or a sudden slowdown in network performance.

• DDoS attacks can take a website down quickly and emphatically. By knowing what you are facing, you can defend against them.

• DDoS Attacks range from brute force incursions to surgical strikes against key components of a network. The right tools to set up defences and a DDoS attack can be stopped cold.


Consider our advice to help prevent attackers from shutting down your network with unwanted traffic. Have an incident response plan in place and talk about DDoS countermeasures in advance with your ISP and a service provider specialising in mitigating these attacks.

Frequently Asked Questions

Q1. What is the most effective way to stop a DDoS attack?

The most effective protection against all DDoS attacks is a Web Application Firewall (WAF), which actively blocks malicious traffic that seeks to exploit vulnerabilities within the application.

Q2. What is the largest DDoS attack mitigated?

The largest reported HTTP DDoS attack reached a staggering rate of over 71 million requests per second (fps), making it the most significant attack.

Q3. What is the difference between DDoS and DoS?

A server is overwhelmed with traffic in a denial-of-service (DoS) attack, rendering a website or resource inaccessible. In a distributed denial-of-service (DDoS) attack, multiple computers or machines are utilized to flood the targeted resource with traffic.

Ideastack Offers host based backup

Host-based backup mostly comes in two types, known as Agentless Backup and Agent-based Backup is a new whir in the field of data recovery. People usually know the agents as small applications installed on the host server to run particular functions in a specific manner.

These applications (agents) are installed on the host server that the admin is required to backup. Agentless backup is the backup without the use of such agents. Whereas, Agent-based backup is backing up the information with the help of an agent or more.

Quite a few vendors claiming that they provide agentless backup, actually add an agent at the beginning of the process and delete it right before the entire backup is made. Surely the rest of the process does not involve any agents, but, in the end, you would not call it an agentless backup.

What is VMDK backup?

The need for Agent-based backup

When choosing an Agent-based backup as a service, you would have to reboot your system after the install because the snapshot driver resides at the operating system kernel level and hence requires the OS to be restarted.

A plus point of an agent-based backup is, since it is loaded with the OS stack, it offers increased control and visibility of the host system that would not be immediately available in the case of Agentless backup. For example, agent-less backups typically need to traverse the file system to determine changes for incremental/differential backups.

This traversal could take longer and be more complex than compared to Agent-based backup which has CBT (Change Block Tracking) and the kernel level.

Agent-based backups rely on local resources to compress and pre-process data before transmitting data across the network to the storage device (NAS/SAN, local USB drive, or remote host).

In comparison, Agentless backups rely more on network resources to transmit application commands across the network as well as data between the target and storage device. If your local network bandwidth is hardly enough to fulfill your needs, then additional network traffic from agent-less backups could impact local network performance.

R1 Soft

The Software we provide is R1 Soft Server Backup Manager. It is a near-continuous backup application for Windows and Linux computers. It provides user scheduled continuous disk-Based online backups for more than one Windows or Linux server.

Every time a user scheduled backup is acted out, Delta Encoding deltas are transmitted to a backup archive efficiently creating a virtual Disk Image.

Frequently Asked Questions

Q1. What is the difference between host level backup and guest level backup?

The DPM protection agent can be installed at both the host and guest level to ensure data protection. At the host level, the agent is installed on the Hyper-V host server or cluster and provides protection for all virtual machines and data files that are running on that host. On the other hand, at the guest level, the agent is installed on each virtual machine to protect the specific workload present on that particular machine.

Q2. What is VMDK backup?

When it comes to backing up a VMDK volume, it typically involves duplicating the virtual disk and transferring it to a different location. However, there are crucial points to consider. Many commercial backup solutions concentrate on creating VM clones or snapshots and may not enable the backup of virtual disks independently.

Q3. What are the different types of virtual machine backups?

There are 03 types of VM backup: full, differential, and incremental. A relatively new addition to the mix is the forever incremental backup.

Backup As A Service (BaaS); For your service from Ideastack

Backup as a service (BaaS) is a way to back up data that involves purchasing online backup and recovery services from a data backup provider rather than performing backup with a centralized, on-premises IT department. BaaS connects systems to a private, public or hybrid cloud managed by an outside provider.

Backup as a service is easier to manage than other offsite services. Instead of worrying about managing tapes or hard disks at an offsite location, data storage administrators can offload maintenance and management to the provider.

This service is mostly used when organizations run out of features to maintain their sites or need new upgrades or resources in their premises for effective backup. Outsourcing backup and recovery to a service provider also keep data accessible or restorable from a remote location in case of an outage or failure.


Points to keep in mind when choosing a service:


The first thing you want to be looking for is ease of use, ease of deployment, and speed of deployment. After all, when you look back at the root cause of why companies are looking at these solutions, a lot of it has to do with the management complexities of existing solutions.


You have to look for technologies that are part of the solution that minimizes the impact of the network.


Essentially after your initial full backup, are the technologies doing things like data deduplication or delta differencing or other block-based change mechanisms, so you’re not doing large volume copies of your backups over and over.


These technologies are out there, but the key thing to look for is whether the incremental or deduplicated backups going over the networks after the initial pull are being deduplicated at your end of the deal or the service provider’s end of the deal.


Another thing to look at is security. The bigger the organization, the more you are going to be concerned with things like access control lists, role-based authentication, and role-based access to systems.


For instance, let’s say you’re a company of 20 people and everyone is using this service, maybe you don’t want everyone to have the equivalent of root-level access to resources.


Be sure that you have some visibility into what’s happening, how much capacity you are using, and what the performance looks like on a daily or weekly basis.


Look for proof of infrastructure.


And lastly, look for evidence of a company in technology stability.



Backing up and recovering data is a necessary discipline in all organizations but is often considered costly, cumbersome, and difficult to manage. Most backup problems happen overnight when you don’t have people watching them, meaning the backup window impacts production time and puts the business at risk of data loss.

People and skills are the biggest cost and challenges in the backup. To buy backup service, contact Ideastack now!
