When it comes to backup solutions, performance is just as crucial as availability. The decisive factor is not so much the time required for backups during regular operations, but rather the speed at which entire systems can be restored. Over the past few years, the volume of data within organizations has increased dramatically, leading to higher demands on storage media. While tape backups were considered the gold standard for decades, their market share has shifted significantly in favor of disk backup solutions, especially since the early 2010s.

Disk Backup Is on the Rise

The era in which tape solutions were preferred over disk backup is definitively over. Storage disks have become increasingly powerful and cost-effective, making disk backup a practical and affordable alternative—even for smaller businesses. In the early 2000s, many companies used disk backup only as a supplementary solution due to cost considerations. Typically, a disk backup was first created over the network to take advantage of higher transfer speeds, and then later transferred to tape without burdening the network. Today, IT managers can eliminate this cumbersome two-step process and perform backups entirely on disk.

This shift highlights the new significance of disk backup compared to ten years ago. The advantages of disk-based backup are especially evident during recovery: restoring data from disk is much faster than from tape. This is due to physical differences—random read/write access on disks is considerably faster than the sequential access required by tape systems. Additionally, disk systems are easier to manage and more robust, as tape drives tend to wear out more quickly due to frequent rewinding.

Another key benefit: disk systems can back up data and perform restores simultaneously—something that is not possible with tape systems. Further arguments in favor of disk backup include higher usage cycles and reduced storage requirements.

Conclusion

The advantages of disk backup solutions are clear: shorter backup windows, significantly faster recovery, and simplified management are just a few of the compelling reasons to choose disk-based data backup. As storage prices continue to fall, the former cost advantage of tape-based methods has largely disappeared. Even in smaller organizations, the daily volume of data to be backed up often reaches the terabyte range, and disk backup solutions have proven their reliability and efficiency in these environments.
