Nauhatallennus, often referred to as tape backup or magnetic tape storage, is a technology used for long-term data archiving and backup. It involves recording digital information onto a magnetic tape medium. This method has been utilized for decades due to its cost-effectiveness and durability for storing large volumes of data over extended periods.

The process of nauhatallennus typically involves specialized tape drives that read and write data to sequential access tapes. Unlike random access storage devices like hard drives, data on a tape must be read sequentially, meaning the drive has to spool through the tape to reach a specific point. This sequential nature makes it slower for immediate data retrieval compared to other storage solutions but ideal for archival purposes where access speed is less critical than storage capacity and cost.

Key advantages of nauhatallennus include its high data density, relatively low cost per gigabyte, and long shelf life when stored properly. Magnetic tapes are also immune to electromagnetic interference and are less susceptible to degradation from power surges. Furthermore, tapes can be easily disconnected from systems, offering a form of air-gapped backup that protects against ransomware and cyberattacks.

Despite the rise of cloud storage and other digital archiving methods, nauhatallennus continues to be a relevant technology, particularly for enterprises and organizations requiring robust, cost-effective, and secure long-term data retention. Modern tape formats offer significant capacity and reliability, making them a viable option for disaster recovery and compliance needs.
