Worried About Data Backup Capacity? LTO Has You Covered
Posted on Monday, August 26, 2019
December 2017 saw the release of LTO-8, offering native backup capacity of 12TB (30TB compressed) per tape cartridge. But as the format nears its second birthday, will tape remain a viable aspect of your backup and disaster recovery strategy?
Tape goes on and on
Given that magnetic tape has existed since the earliest days of computing, it is surprising to see the technology still in day-to-day use. But as demand for capacity grows exponentially, no other technology has come close in keeping pace.
Demand for capacity is of concern, however; a 30TB cartridge may not be sufficient or fast enough to complete a nightly backup job, even with an automated tape library. Does that mean it’s time to switch to a disk-based alternative?
Not necessarily. LTO Ultrium technology continues to evolve and develop– and theoretical capacity is doubling with each iteration. When LTO-9 is released to market (probably within the next 12 months), each cartridge will store 24TB natively (60TB compressed).
A bright future for tape
The LTO Consortium that oversees the technology isn’t stopping there, either. Development is already underway for v10, 11 and 12, too. When LTO-12 arrives, every tape will hold 192TB of uncompressed data. As businesses move more of their workload to the cloud, it is highly likely that these capacity gains will keep pace with demand.
The logic-defying longevity of LTO Ultrium has been discussed many times on the CDS blog – and looks as though we will continue to do so in future. It also looks as though the exponential capacity growth of tape means that it may even outlast magnetic spinning disk in the corporate computing environment.
