Every enterprise should engage in end-of-life planning for data storage media. That extends to tape cartridges; while tape is often considered more reliable than other forms of data storage, all formats can become less reliable with regular use.

LTO (Linear Tape Open) Ultrium is a high-capacity format designed for longevity — but like every other data storage medium, it has a limited operating lifespan. 

How many times can I use an LTO tape before it becomes less reliable?

Maxell, one of the major manufacturers of LTOs, recommends replacing LTO tapes after “approximately 250 [uses].” For general applications, this is an excellent rule of thumb. 

But the true durability of LTO Ultrium may be much higher. In a white paper detailing LTO Ultrium testing processes (PDF), Hewlett Packard Enterprise (HPE) notes that typical logo compliance tests include locate/rewind/append testing, during which a “locate-rewind” cycle is repeated 250 times. HPE testing passes tape through the drive 2,500 times — applying 1000% more stress than typical logo tests. 

“The benefit to the user is that the data cartridge performs under the most extreme daily conditions,” the white paper notes, “reducing the number of failed backups and restores and minimizing the risk of disruption to the network.”

For general purposes, LTO tapes should be cycled out after 250 uses.

While HPE’s testing indicates that some LTO tapes are capable of handling extreme stress, the goal of backup/archive is to minimize factors that could compromise reliability. Even if you’re dealing with fully redundant data, a damaged cartridge can lead to lost time — and if you’re not dealing with full redundancy, damaged media may be catastrophic. 

To reiterate: Your backup/archive strategy should establish the end-of-lifespan (EOL) for LTO cartridges at around 250 uses. Few organizations will reach that milestone. 

For long-term storage, the lifespan of the actual tape becomes more important than the lifespan of mechanical components. Most manufacturers estimate that LTO tapes will provide dependable data storage for 15-30 years in appropriate storage conditions.
