What are backup devices?
Storage devices dedicated to data protection are specialist systems designed for storing, versioning, and quickly restoring information in the event of data loss. Their primary purpose is to protect against hardware failures, user errors, ransomware attacks, and natural disasters.
The difference between standard storage and backup devices:
- Standard storage systems prioritise performance and low latency for production applications.
- Backup devices focus on data durability, offline operation, deduplication, and compliance with regulations such as GDPR.
Key features of professional backup solutions include:
- automatic incremental and differential backups,
- AES-256 encryption,
- WORM (Write Once Read Many) functionality protecting against modification of stored data,
- scalability allowing for expansion without downtime.
Basic principles of backup systems operation
The backup mechanism is based on three strategies: full, incremental, and differential. A full backup includes all data, an incremental backup records only changed files since the last backup, and a differential backup captures all changes since the last full backup. This combination optimises both storage space and recovery time.
Automatic backups
Eliminates the risk of human error. Backup allows for scheduling, media rotation, and integrity verification through checksums. Regular backups following best practices minimise the risk of data loss.
Integration with existing IT infrastructure
Includes virtual environments (VMware, Hyper-V), file servers, NAS/SAN systems, and cloud object storage.
Security protocols and data encryption
Protect backups from unauthorised access. Encryption at rest and during transfer, access control, and detailed audit logs are standard in professional solutions.
Benefits of using professional backup solutions
Protection against the loss of critical business data is the primary benefit.
- In the event of a disk failure, malware attack, or user error, there is the possibility to create a backup of the data and quickly restore it.
- Compliance with GDPR and industry regulations often requires data to be stored for 10-30 years. LTO tapes with WORM functionality meet these requirements, ensuring the immutability of stored information.
- The reduction in costs associated with data recovery is significant. The cost of a professional backup system is a fraction of the potential losses resulting from downtime or legal penalties.
Features of backup storage devices
Understanding key technical parameters will help in selecting the optimal storage device for specific backup requirements.
Capacity and scalability
Raw capacity differs from usable capacity when considering RAID, deduplication, and compression. LTO-10 offers a native capacity of 30-40 TB, and with data compression that reduces the size of stored files, the effective capacity can reach up to 100 TB. Compression allows for secure storage of more information on the same medium, which is particularly important when archiving large datasets. When planning the capacity of a device, it is worth considering the expected data growth over the next 3-5 years.
Data transfer performance
Write and read speeds determine the time taken for backups and restorations. NVMe SSDs achieve several GB/s sequentially and hundreds of thousands of IOPS, while HDDs typically offer below 500 MB/s.
Reliability
MTBF (Mean Time Between Failures) indicates the expected durability of devices. For SSDs, the TBW (Total Bytes Written) parameter is important, indicating the number of write cycles. LTO tapes have a lifespan of 20-30 years under proper storage conditions.
RAID 5/6/10/50/60 mechanisms, redundant power supplies and fans, hot-swap capabilities, minimise the risk of downtime. Geographical replication is the process of creating and storing backup copies of data in different geographical locations. This ensures that in the event of a local disaster, such as a fire, flood, or infrastructure failure, data remains safe and accessible from another location.
Geographical replication increases the resilience of the backup system, minimising the risk of data loss and downtime for the business. This is particularly important for enterprises that must meet high requirements for continuity and information security.
Security features
AES-256 encryption of data at rest and during transfer is standard. The WORM function prevents modification or deletion of stored copies.
Access control, detailed audit logs, and compliance with certifications (ISO, SOC, CSA) ensure data security and compliance requirements are met.

Frequently Asked Questions
What backup device should I choose for a company with 100 employees?
For an organisation of this size, an optimal choice is a 4-8 bay NAS system with RAID 6 or a dedicated backup server with a disk array. For large data volumes, consider an entry-level LTO-8 tape library. A hybrid solution with replication to the cloud will provide additional protection in a secure offsite location.
Are external SSDs sufficient for professional backup?
External SSDs are best for fast, frequent backups of personal files. They work well in small businesses or as an additional layer of protection. Limitations include scalability and the need for manual management. For professional use, NAS systems with RAID or tape libraries that provide automation and redundancy are recommended.
Is an SSD or HDD better for backups?
External HDDs are best for long-term storage of large amounts of data, offering greater capacity at a lower price than SSDs.
How often should backup storage systems be updated?
The typical lifecycle of backup devices is 5-7 years for disk and NAS systems. Tape libraries can operate longer, but replacing drives every 2-3 generations of LTO is necessary to maintain compatibility. Planning for upgrades should consider data volume growth, new threats, and compliance requirements.
What are the maintenance costs of professional backup systems?
Total cost of ownership (TCO) includes: the purchase price of devices, backup software licenses (often annual), energy and cooling, manufacturer service and support, training, and potential data migration. LTO tapes offer the lowest cost per TB over the long term but require higher initial investments. Cloud solutions have a low entry threshold, but costs increase with data volume.
What does the 3-2-1 strategy mean?
The 3-2-1 backup strategy involves maintaining three copies of data on two different media, with one copy stored in a separate location, such as in the cloud. External hard drives are a classic backup medium, offering enough space for all important data, and restoring them is simple by connecting to a computer.
Cloud backups are stored on remote servers accessible via the Internet, providing an additional layer of security against physical threats such as fire or flooding.
