Tape Storage for backup and archiving data
Are you tired of traditional storage methods that are slow, unreliable, and expensive? Look no further than tape storage! While it may seem like an outdated technology, tape storage has come a long way in recent years and is now one of the most efficient and cost-effective ways to backup and archive data. In this blog post, we'll explore the benefits of tape storage, how it works, the different types available, and when to use them. So sit back, relax, grab some popcorn (or your favourite snack), and let's dive into the world of tape storage!
The Problem with Traditional Storage Methods
Traditional storage methods, such as hard disk drives and solid-state drives, have been the go-to options for many years. While they may be convenient, these types of storage devices come with their own set of problems.
Firstly, traditional storage methods can be quite expensive. The cost per gigabyte is higher compared to tape storage. This becomes especially problematic when you need to store a large amount of data over time.
Secondly, there's always the risk of hardware failure when using traditional storage methods. If your hard drive fails or becomes corrupted, you could lose all your valuable data unless you've made backups elsewhere.
Thirdly, storing large amounts of data on traditional devices can take up a lot of physical space in your office or server room. This means that if you need more space down the line, you'll have to keep buying new drives and constantly expanding your infrastructure.
While traditional storage methods may seem like a good option initially due to their convenience and accessibility, they are not always practical for long-term backup and archiving needs.
The Benefits of Tape Storage
Tape storage has been around for decades and is still considered a reliable, cost-effective solution for backup and archiving data. While other storage methods such as hard drives or cloud services may seem more modern, tape storage offers its own set of benefits.
One major advantage of tape storage is its durability. Unlike hard drives that can be damaged by physical shocks or exposure to magnetic fields, tapes are less susceptible to damage from external factors. This makes them an ideal option for long-term backups and archives.
Another benefit of tape storage is its scalability. As your business grows and generates more data, you can easily expand your tape library without the need for additional hardware or software upgrades. This makes it a flexible and practical solution that can adapt to changing needs over time.
In addition to being durable and scalable, tape storage also offers high-capacity options at a lower cost compared to other forms of storage media. With the ability to store multiple terabytes on a single cartridge, tape storage provides significant savings in terms of both space and budget.
While newer technologies continue to emerge in the world of data backup and archiving, there's no denying the unique benefits that tape storage brings to the table when it comes to reliability, scalability, affordability, and longevity.
How Tape Storage Works
Tape storage is a reliable and cost-effective method for backing up and archiving data. But how does it actually work?
At its core, tape storage uses magnetic tape to store data in long, thin strips. These tapes are typically enclosed in protective cartridges to prevent damage from dust or debris.
When data needs to be stored on the tape, it is first converted into binary code - a series of 0's and 1's that can be read by the computer. This code is then written onto the magnetic surface of the tape using a device called a write head.
To retrieve the stored data, the process works in reverse. The read head detects fluctuations in magnetism on the tape and translates them back into binary code that can be understood by computers.
One advantage of this process is that tapes have no moving parts aside from spinning reels used during reading or writing processes which reduces mechanical failures compared to other forms of storage devices such as hard drives.
While it may seem like an antiquated technology compared to modern cloud-based solutions, many companies still rely on tape storage for its reliability and low cost per gigabyte.
The Different Types of Tape Storage
When it comes to tape storage, there are a few different types of tapes that you can choose from depending on your needs. Linear Tape-Open (LTO) is one popular type of tape storage that offers high capacity and fast access times. It uses an open format, meaning that multiple manufacturers produce LTO drives and cartridges.
Another type of tape storage is Digital Data Storage (DDS), which is commonly used for small-scale backup solutions. DDS tapes have a lower capacity compared to other types of tapes but they are more affordable and offer reliable data protection.
Advanced Intelligent Tape (AIT) is another option for those looking for high-capacity storage options. AIT has been designed specifically for the enterprise market with features like error correction and automatic self-cleaning heads.
There's the 3592 tape format which offers very high capacities up to several terabytes per cartridge in some cases. This makes it ideal for use in large scale data centers or archival systems where long term retention of critical information is essential.
Choosing the right type of tape will depend on how much data you need to store, how often you need to access it and what kind of budget you're working with.
When to Use Tape Storage
Tape storage is a reliable and cost-effective solution for long-term data backup and archiving. It offers excellent durability, portability, and compatibility with legacy systems that make it an ideal choice for certain use cases.
One of the primary scenarios where tape storage shines is in industries that deal with large amounts of sensitive data on a regular basis. For example, healthcare organisations, financial institutions, and government agencies may use tape storage to keep decades' worth of patient records or financial transactions securely stored away from prying eyes.
Another area where tape storage can be invaluable is in disaster recovery planning. In case of a catastrophic event like a fire or flood, having physical backups on tapes that are stored offsite ensures that critical data remains available even if the primary infrastructure is destroyed.
Businesses may also choose to use tape storage as part of their compliance strategy. Certain regulations require companies to keep specific types of data archived for extended periods; using tapes can help ensure these requirements are met without overspending on more expensive solutions.
While not suitable for every situation or organisation's needs, there are many instances where tape storage can provide significant benefits over other forms of backup and archiving methods.
Tape storage is a reliable and cost-effective solution for backing up and archiving data. While traditional storage methods like hard drives may seem more convenient, they are not always the best option when it comes to long-term data retention.
Tape storage offers numerous benefits such as high capacity, durability, and longevity. It also reduces the risk of data loss due to hardware failure or cyber attacks.
There are different types of tape storage available in the market today that cater to various needs and budgets. It's important to choose the right type based on your requirements to get optimal results.
So if you're looking for a secure and efficient way to store your critical data, consider implementing tape storage into your backup strategy. With its proven track record over decades, it's definitely worth considering as an essential component of any organisation’s backup infrastructure.

Object Storage Safe Scalable Storage
Object storage is a method of storing and managing data as discrete, self-contained objects rather than using a traditional file hierarchy. In this storage architecture, each object contains the data itself, associated metadata, and a unique identifier. This approach is different from file-based storage, where data is organised in a hierarchical file system.
Here are some key characteristics and features of object storage:
- Scalability: Object storage is designed to scale horizontally, allowing for the storage of massive amounts of data. It can easily handle petabytes or even exabytes of information, making it suitable for organizations with large data requirements.
- Metadata: Every object in an object storage system is associated with metadata, which provides descriptive information about the object. This metadata can include details like the object's name, creation date, size, and other customizable attributes. Metadata plays a crucial role in object identification, searchability, and data management.
- Unique Identifier: Each object in object storage is assigned a unique identifier, typically referred to as an Object ID or Object Key. This identifier distinguishes objects from one another and enables efficient retrieval and management of specific objects.
- Flat Address Space: Object storage systems use a flat address space, which means that objects are stored and accessed directly through their unique identifiers rather than navigating through a hierarchical directory structure. This provides faster access times and simplified data management.
- Redundancy and Durability: Object storage systems often include built-in redundancy and data protection mechanisms. Object storage platforms typically use data replication or erasure coding techniques to ensure data durability and integrity even in the event of hardware failures.
- Accessibility and Distributed Access: Object storage is designed to be accessible over a network. It provides a uniform interface, such as Representational State Transfer (RESTful) APIs, allowing applications and users to easily retrieve and manipulate objects. Object storage can be accessed locally within a data centre or over a wide area network (WAN) for distributed access.
- Versatility and Use Cases: Object storage is versatile and can be used for various purposes, such as backup and restore, content distribution, archiving, data lakes, and as a foundation for cloud storage services. It is well-suited for handling unstructured data like documents, images, videos, log files, and other types of large-scale data.
Overall, object storage offers a scalable, durable, and flexible approach to storing and managing large amounts of data. Its design focuses on simplicity, efficiency, and accessibility, making it an increasingly popular choice for businesses dealing with vast and growing data volumes.

SAN vs NAS
The differences between a SAN & NAS
A storage area network and network attached storage both provide data storage across a network to deliver either file or block storage. SAN vs NAS are two completely different types of storage.
SAN storage is a block-level storage protocol. Blocks are presented to the application or operating system as LUNs (logical unit numbers, these are provided by the SAN storage and connect to the server via a HBA (host bus adapter). The data blocks appear as locally attached storage (DAS), when in reality the storage resides on the SAN. SAN storage uses either fibre channel or iSCSI to create the SAN and this is normally a separate dedicated network.
NAS storage provides a centralised file sharing area for storing files. The NAS has an operating system that uses variants of Linux or Windows Storage Server and this integrates directly with LDAP or Active Directory to allow designated users to store and access files across the network.
A SAN normally has multiple storage arrays, servers and network switches connected to the same network.
SAN vs NAS Performance
The debate regarding SAN vs NAS continues to be discussed. In most data centres today running 32Gb/s Fibre Channel the SAN would win. If a business starts to deploy 100Gb/s Ethernet then you could argue the NAS would win, but remember you can also have an iSCSI SAN which would in effect be faster than the NAS over the same network.
SAN storage is faster than NAS due to the lower processing overhead the fibre channel and iSCSI protocols use, this enables almost wire speed to transmit data across the SAN. Both systems can have HDD’s, NVMe & SSD drives internally, but performance will be greater across a SAN.
SAN storage connectivity
Connecting SAN storage to your storage area network will utilise one or more of the following:
8/16/32/64Gb/s Fibre channel = FC SAN
1/10/25/100Gb/s Ethernet = iSCSI SAN
A SAN normally has multiple redundant switches connected to redundant storage arrays, from these arrays the storage is carved up and served out as data volumes. These volumes could provide storage for virtualisation, local disk storage to servers attached to the SAN or provides disk storage to backup appliances where block storage is a key requirement.
NAS storage connectivity
Connecting NAS storage to the network normally uses Ethernet and these are the normal network connections.
- 1/10/25/100Gb/s Ethernet
- 10/25/100Gb/s FCoE
A NAS normally connects to one or two network switches. The NAS storage is then carved up into volumes, these volumes are then used to provide files and folders to be accessed across the network as CIFS/SMB/NFS shares to which users map to their desktops.
How do SAN vs NAS storage differ?
SAN – Storage Area Network
NAS – Network Attached Storage
A NAS has an operating system, CPU, memory, data storage, network connections; SAN storage on the other hand has a CPU, memory, data storage, network connections and an embedded operating system for storage management. SAN storage will not allow you to add extra functionality i.e. photo sharing app. SAN storage is more secure than NAS storage as the embedded operating system cannot be changed or modified.
Normally fibre channel is a point-2-point protocol, this means the LUN can only be seen by the server connected host, although there is software available to share LUNs with multiple hosts and this is normally used in post-production to share large files across the network, but lock files when they are being accessed.
A NAS on the other hand by default shares all the available volumes across the network to any user who has file/folder permissions.
Which should I choose?
In the SAN vs NAS debate, ultimately it boils down to your budget and requirements.
A SAN requires a totally separate dedicated network, although iSCSI will operate over an existing Ethernet network, it is recommended that it also resides on a dedicated network.
Whereas a NAS will happily sit on your network and provide local shared files and folders for users.
If you want performance and the most secure infrastructure, then choose a SAN. In the end it is horses for course NAS for file and SAN for block.
