Whether it’s a secondary copy of valuable data that’s already stored on another medium or providing another level of offline assurance to a disk-to-disk system, LTO tape delivers a cost-effective means for restoring your data quickly.
CAPTURE AND OFFLOAD
Storage media rarely is a one-size-fits-all solution. For applications where more expensive media – such as solid-state disk – is used to capture initial content or data, LTO tape is a perfection solution for offload and retention, such as video production or oil/exploration data aggregation.
HIGH CAPACITY TRANSFER
Even with some of the fastest connections, transferring Terabytes of data to the cloud or a remote data center can take days and tax your network resources. A shipment of an LTO tape can not only get the data there faster in some cases, but it also provides a backup to the original.
LONG-TERM ARCHIVE & OFFLINE STORAGE
Sometimes you don’t need data readily available, but it might need to be accessed at a later time. LTO Ultrium tape storage can provide for years of protection at a cost much lower than other storage solutions.
Sometimes files need to be in an intermediate state between online storage (very rapid access to data) and offline storage (infrequent access to data) called nearline storage. With high data transfer speeds, low cost and high capacity, LTO tape is perfect for managing nearline data and bringing it online very rapidly when required.
Backup or Archive: There’s a Difference
Archive and backup are words that can be commonly interchanged, but in storage they’re actually very distinct processes with different objectives.
An archive is a primary copy of files that aren’t needed immediately. They’re typically stored on a less-expensive, highly-reliable and durable medium so that the original storage device can be reused. Typical applications include retaining permanent records – such as compliance – and data management. Content, such as music and video, is also typically archived for later use. Archives are rarely overwritten.
A backup is a secondary copy of original data. It’s primarily used to restore data in the event of an emergency, such as a disk failure or disaster recovery. Backups are typically overwritten with new data at a later time, allowing for reuse.
|Method||Original removed from production||Copy of production data|
|Purpose||To retain data for future use, for regulatory compliance, e-Discovery support, Helps shorten backup and recovery windows, Reduce total costs of storage||To recover data in the event of data loss destruction, corruption etc.|
|Data policies||Retention periods, Access controls||Recovery Time Objectives (RTO), Recovery Point Objectives (RPO)|
|Data handling||Data cannot be altered or deleted before retention expires||Duplicate copies are periodically overwritten|
|Retention Period||Long term||Short term|
