Tape storage has been around for a long time and despite many premature notices of its death, it looks set to be around for a decade or two yet. What is changing, however, is the role of tape. Where once it was the target of choice for backup, it now finds a new role in longer-term storage and archiving of data. So, despite disk's encroachment onto tape's former stronghold in backup, there is still good reason to buy and implement tape storage products.
In this Special Report, you'll find an exploration around tape's role in the archiving space, as well as articles on the key points you'll need to think about when procuring and managing tape storage hardware, such as how tape backup compares with disk backup, how to select a tape library, where tape fits into contemporary data protection, what you need to know about tape encryption, how to look after tape for maximum longevity and the main tape rotation schemes in use by storage professionals. Use this report as a resource for learning everything you need to know about tape storage.
With disk getting cheaper and more stringent compliance requirements, tape is increasingly being pushed toward a main role as archive medium. Learn why tape is well-suited for the role and what benefits the new LTO-5 format bring to tape archiving. Also, get advice for establishing tape archive policies at your organisation.
In this podcast interview, Ian Lock, service director for storage and backup with GlassHouse Technologies (UK), analyzes tape backup vs disk backup and explains how best to use tape in a modern backup strategy.
When choosing a tape library, the key considerations surround software features, the speed of throughput and capacity required, as well as compatibility with your backup setup. In this article Rick Cook walks you through the main points to have in mind when specifying tape libraries for your organisation.
With all the scares about lost data in recent years, encryption is high on the agenda for many storage professionals, and securing data on tape is a key location for such security measures. But tape encryption needs can't be approached in a casual way. You'll need to consider whether encryption will affect your throughput and media capacities, whether encrypt should be done on the tape hardware or using backup software and how you'll store encryption keys. We look at all these issues and more in this article.
Released earlier this year, LTO-5 is the latest generation of tape formats. It offers tape media with throughput of up to 280 MBps and capacity of 3 TB per tape (compressed). Find out all you need to know about LTO-5.
Tape is a relatively cheap and durable storage media, but it does need looking after. Dust and dirt and mechanical failure can result in lost data, and tape storage cartridges need to be looked after properly, and occasionally re-tensioned and rewritten. Find out all you need to know about looking after magnetic media in this article.
All effective tape backup setups need a tape rotation system. In this article we look at the common tape rotation systems, from Round Robin through Grandfather-Father-Son to the Tower of Hanoi.
