LTO (Linear Tape Open) is an open-format tape storage technology that is compatible with various storage media products.These are the five main tape formats that you should know about: They vary in capacity, data transfer speed, load time, etc. There are multiple tape formats on the market. To compete with disk-based or cloud-based storage, manufacturers of magnetic tape backup systems have to constantly develop and enrich tape functionality. Also, tape cartridges and cassettes can deteriorate over time if kept in unfavorable conditions, resulting in unwanted data loss. Note that tape drives are sequential-access devices, meaning that in order to access a specific data block, you first need to read all the preceding data blocks. For example, for the purpose of reading or writing digital data onto a tape, you should use a tape drive. However, magnetic tape has its disadvantages. Nevertheless, tape drive backup still remains one of the main options for storing data due to its large storage capacity, cost-effectiveness, and reliability. These characteristics made hard drives an effective alternative to tape backups. By that time, hard disks offered a lower price, higher capacity, and better usability than magnetic tapes. Tape was the primary way of storing digital data from the 1960s through the mid-1980s – up to the point when hard disks became more widespread. They are especially useful for archival and data compliance purposes. Tape backups are currently used as secondary backups for long-term offsite storage of critical data that doesn’t need to be accessed on a regular basis. Tape backup is a data protection approach that involves storing digital data copies of primary data on tape cartridges or cassettes.
