Cloud Archival

Secure and durable storage for archival

As magnetic tape has been at the forefront of data storage

Tape has been the medium of choice for backup and archive in enterprise organisations for more than half a century. This isn’t surprising, as magnetic tape has been at the forefront of data storage since IBM released the first tape drive 60 years ago in 1953.

But, now the cloud has begun to offer more compelling solutions and the opportunity to use cloud archiving services and to dispense with traditional in-house technology.

Are we near the tipping point where tape could be supplanted by cloud archiving in the enterprise?

Many organisations make the mistake of retaining data backups and calling this an archive. But, backup and archive are very distinct and have separate requirements.

Backup provides recovery from unexpected data loss (user error, data corruption, hardware failure) whereas an archive is a long-term store of inactive or low-activity data retained for future use, whether for compliance purposes or historical data mining.

Traditionally Tape media is used for long term archival, however tapes media have few challenges

Technology refresh cost

LTO technology gets refreshed every 18 months, it is not simply the cost of media that must be considered, but also that of tape drives, tape libraries and archive software. Where technical decisions change the hardware platform, data may have to be re-indexed or hardware may have to be maintained beyond end-of-life supplier support, which can significantly add to costs and the overall total cost of ownership (TCO) of an archive solution;

Application dependency

Tape might be integrated with proprietary solutions such as direct writing of archive data from an application that don’t scale or create future dependencies for data access. Data written from one backup software cannot be read by other software.

Cloud Archival

Cloud archiving offerings provide an additional layer above the pure technology of the storage medium. They abstract the underlying storage platform by delivering archive as a service, with the implementation of that service the responsibility of a service provider.

Customers should expect cloud archiving to be competitive on cost compared to using tape and in-house processes and to provide value-add functionality, such as:

01. Geographical redundancy

Cloud archive services should provide for multiple copies of data in diverse locations, mitigating the risk of data loss from technology failures, (it should be remembered that an archive copy may be the only retained copy of a piece of data);

02. Advanced
search

Data is typically indexed at ingestion into cloud archive services, providing rich search capabilities. Data should be re-indexable if required;

03. Content management

Cloud storage also provides content management solution to manage the large amount of content stored on cloud.

Amazon Glacier is a secure!

Amazon Glacier Archival Storage

Amazon Glacier is a secure, durable, and extremely low-cost cloud storage service for data archiving and long-term backup. Customers can reliably store large or small amounts of data for as little as $0.004 per gigabyte per month, a significant savings compared to on-premises solutions. To keep costs low yet suitable for varying retrieval needs, Amazon Glacier provides three options for access to archives, from a few minutes to several hours.
