Backing up your data in the cloud

October 11, 2012 |

Nothing is more important and yet forgotten than backing up files to protect from data loss. Companies put off backups, and the importance isn’t realized until one day the data corrupts and the company loses transactions.

Rackspace offers a new backup system that allows users to back up individual files without the long, drawn-out process of complete system backups. The service, introduced in June, offers encryption, unlimited backups, and incremental backups for $0.15 to $0.10 per GB per month. Users can choose to save the backups for 30 days, 60 days or indefinitely.

The service was originally open to certain customers, but Rackspace has opened the service to all Cloud Server customers, and it is free for Managed Cloud users.

The most interesting advantage for this backup system is the API. Typically, companies need to perform backups on off-hours, so the backups do not cause too much downtime or performance … Read More

Setting Up ELMAH in the .NET Project

ELMAH’s settings are placed in the web.config for the .NET project. Every cloud application for a website has a web.config. The lines of code needed in the web.config are on the ELMAH Wiki. In the “connectionString” section, the database name, drivers and username and password are … Read More

Before the turn of the millennium, augmented reality was only seen in sci-fi movies. While still far from being a house-hold item, the technology continues to improve, and several companies are experimenting with new products with a computer-generated display. Augmented reality comes in the form of head-mounted displays or retinal displays. The most popular and anticipated is Google Glasses, which lets the user take images and videos and view a virtual world through retinal lasers.

The technological advancement is the future for individuals and small businesses looking for the next step in cloud computing.

Head-Mounted Displays versus Retinal Displays

Head-mounted displays are bulky, and they do not offer the extended peripheral vision that a retinal display can offer. Head-mounted displays are used in machinery such as cockpits of planes to train new pilots with the advanced equipment. Head-mounted displays … Read More
