Should You Review Your Tape Archives?

If your only exposure to the world of data storage has been in the context of a small to medium-sized business or a startup, you’d be forgiven for thinking that magnetic tape is a relic from another era of enterprise computing. Once the de facto standard for long-term data retention, the format no longer gets much airtime in an age of cloud backups and tumbling HDD prices.

Nonetheless, rumours of the magnetic tape’s demise have been greatly exaggerated. According to an Information Age article from September 2014, all ten of the world’s biggest banks and telecoms firms, as well as eight of the world’s ten biggest pharmaceutical companies, are tape users. And as trends like big data pick up steam, there’s more interest than ever for organisations to invest in low-cost, high-volume storage for offline data.

For all their advantages, though, tape archives need to be looked after. It can be tempting to think that business records are out of sight, out of mind once they’re filed away in a format proven to last upwards of decades, but this is a mistake. The reasons for creating a tape archive aren’t trivial – regulatory compliance, mainly, and disaster recovery – and you don’t want to discover at the critical moment that your records are patchy.

Some tapes might be unlabelled

Obviously, you can’t run a successful tape archive if you can’t say for sure what resides on some of your tapes. Unlabelled media isn’t uncommon and can have a wide range of repercussions, among them legal risk – the data stored on a tape might be kept for longer than the mandated retention period, for example, or the organisation might be unable to respond in time to a regulator’s request.

The other issue is that if you’re attempting to restore a backup, poor labelling can add more than a few hours of downtime to the overall costs incurred by your business.

Damage might occur in storage

Stored correctly, magnetic tapes can last for decades – but the keyword really is ‘correctly’. All sorts of damage can occur to tapes in storage and transit, so it’s worth conducting regular reviews to check that your data is still recoverable. Dampness, extremes of temperature, fire and smoke damage are just a few of the things that can render tapes useless without expert intervention, and none of them are necessarily apparent until after the fact.

You might need to migrate to a new archive system

Some organisations run into trouble when they’re trying to restore data from tape archives because they no longer have the hardware or software required to do so. If you’re storing business records from two to three decades ago, it’s likely your IT infrastructure has gone through more than a few renewals in the interim.

Conducting a review of your tape archives should help you to determine whether or not the format of the data would be an issue or a bottleneck in a disaster recovery scenario, requiring a migration to a new system.

Some data might need to be destroyed

Finally, if you don’t have a formal data destruction policy in place, your tape archive may contain data that you’re required by law to delete or modify. This could include personal information on customers that you no longer have a reason to retain, as well as documents relating to former business partners.
