Glyphstock and optical media: security for your data

23/02/2017

Since they appeared in the market back in the 80s, optical devices have not only lasted, but have become essential for those who want to provide a security bonus to their data.

We could dedicate hundreds of words to defend the qualities of optical discs and the technology they use, but we believe that a few will suffice to tell you why we trust them to store your data and how that can give you peace of mind...

Why do we use optical media at Glifstock?

In short, because they lack mechanical and electronic parts and the data is sculpted by laser on the sheet of thin reflective metal layer (24 carat gold or a silver alloy). In addition, the reflective layer is covered by an acrylic finish with protection against ultraviolet radiation, creating in this way a surface that favors the protection of the data.

A very important difference for us in relation to magnetic media is that in optics, and being the data 'sculpted' (usually by laser), these can not be erased or modified. Manipulated, in short.

Another advantage that we consider when deciding on them for the service we offer is that it allows us to create a cold, offline data warehouse... and therefore inaccessible to a cyber attack. The sum of all the exposed, together with the technological advance that allows to create standardized media with 100GB capacities -even more-, make it the ideal way to store a large volume of data, safely and in the long term.

When is Glifstock using the service?

All customer information that creates and uses our glyphs is stored in optical media and in a redundant way, in delocalized warehouses. In addition, the copies that we send to you are also recorded on that support, so that the user can have a local copy of their data at their fingertips.

However, zero risk does not exist. What does Glifstock do to protect its optical devices?

As a first security measure, and although this requires time, a check of the integrity of the recording is always made. It is done systematically for each medium.

It is true that the deterioration of optical media could be damaging the metallic layer. To avoid this, the discs are manipulated by a robotic mechanical system. Even so, a second geodeslocalidated, sealed copy is created outside the robotic circuit and stored in a controlled atmosphere to prevent oxidation. It is like a capsule where time does not seem to pass and wear is kept away.
