Backup server data at the block level bypassing the file system and reading data directly from the disk or volume. Block-level backup provides advantages over traditional file backup technologies including the speed of completing a backup operation, a drastic reduction in disk and network I/O, the ability to perform backups as often as every 15 minutes and no performance penalty for servers having a large number of files.
With urban populations worldwide swelling, there’s an urgent need to calculate the sustainable performance of the buildings that we live and work in. But the variety and complexity of methods available can seem overwhelming. This is where ISO 21930:2017 comes into play.
The latest edition of ISO 21930:2017, Sustainability in buildings and civil engineering works – Core rules for environmental product declarations of construction products and services, will help assess the eco-friendliness of a building or infrastructure projects using a common method for expressing environmental product declarations (EPD).
An EPD for a construction product is a transparent declaration of its life-cycle impact (incorporating raw material production, construction, operation, maintenance and decommissioning). This in turn provides the information needed to assess the environmental impacts of an entire building or civil engineering works. What’s key about EPDs is that they provide a transparent, independent and reproducible analysis of the environmental impacts of construction products and give detailed information with sound data and figures. As a “sustainability passport”, EPDs form the basis for designing green buildings and other civil engineering works.
