Today, all eyes on the tech world were focused on Apple, who as expected, wowed onlookers with its yearly sneak-peek of what’s to come from Cupertino. And among those announcements came a bombshell for those of us in digital imaging. A major product announcement came in the form of high-resolution, near-print quality image displays that are available beginning right now, on a high-end line of Apple MacBook Pro computers. These Retina displays are boasting 2880 x 1800 pixel densities, at a resolution of 220 pixels per inch, equivalent to some 5.2 megapixels.

By comparison, if you’re reading this on a desktop or laptop, you’re likely seeing it at a resolution of between 72 and 150 pixels per inch, weighing in at a mere 1.2 to 1.8 megapixels.

At the moment, this is only available (at least for desktops and laptops) on a very top level, premium line of systems whose price tags start at $2,200. However, we can expect over the next 12-18 months for these types of displays to become more common on less expensive computers, on all operating systems. And of course, displays of this resolution (and higher) are already available on tablets and mobile devices, such as iPads, iPhones and some high-end Android equivalents.

The immediate impact is that most web-formatted images that are meant to be displayed at the customary 72 ppi, will appear much smaller, and less defined, on these newer screens. This will mean that in order to deliver quality image content to users in the long term, images will have to be larger and more detailed. It’ll be possible for a greater amount of detail from high-resolution digital images to be seen online, instead of having to print these images to get the full effect. Most digital text will be clearer to read. Our computer screens will better approximate print. And hopefully, using a computer to read a document should be a lot easier on users’ eyes.

Fortunately for us at RUcore (and many other digital preservation projects), we’re still well ahead of the curve, with imaging preservation standards that set a baseline of 400 to 600 dpi scanned images. This was originally meant to help us re-create the full print quality of a lot of the documents we scan and preserve, should someone, someday decide to re-print them. But now, it’s clear that computer displays of all types are evolving to catch up with print, and give users an image experience that was never before possible on an electronic screen.

The Media Preservation Site at Indiana University – Bloomington (IUB) makes its message loud and clear the moment you first set your eyes on it: “Our History is At Risk.”

Home to at least 3 million media objects, including sound and moving image recordings, photos, documents, and artifacts, IUB has come to grips with the issue at hand: a great deal of their heritage is locked within obsolete electronic and analog playback formats for sound and moving images.  As an old format becomes obsolete, it gets harder by the day to find working equipment to play back these objects.  And that assumes that the objects can be played back, not having succumbed to age, wear and physical decay. Lacquer from old aluminum audio discs can delaminate, making them unplayable. Video tapes from the 1960s, 70s and 80s can suffer from a condition where the binding agent that holds the recording material to the plastic base sheds, allowing audio and video recordings to literally flake into nothingness. Film, too, has its own serious decay problems.

With its vast collection, faculty and staff at IUB knew the situation could become serious if nothing was done.  Their first step was to take stock of the situation, and consult outside experts (myself included) to get input how how best to address the problem.

Their efforts began nearly 18 months ago when a group of IUB faculty and staff, concerned about the potential fate of important special collections on campus, approached their Office of the Vice Provost for Research about the critical issues of media, and to impress upon them that time was of the essence to address these issues.

“Even though [IU Bloomington’s] needs are now documented, and it is far better equipped than most universities in the country to meet them, there is no guarantee that IU can adequately preserve its collections in the near future.”

The culmination of their efforts to date have been documented on the IUB Media Preservation Website, where they document their comprehensive effort to preserve IUB’s vast audio, video, and film holdings.  Some important documents from their study and efforts including IUB’s Director of Media Preservation Services Mike Casey‘s  Media Preservation Survey (PDF), outlining the collection holders, preservation stakeholders, the risks involved, and potential preservation strategies.  A follow-on public report (12MB PDF) also lays out the situation and what steps are being taken to save their special collections and historic content.  Continued engagement, updates, and discussion on decisions made and procedures undertaken are regularly made available on their Media Preservation Blog.

IUB has many years of work ahead of it, not only to transfer older content into more modern digital formats, but also to continue to maintain those archives, preserve new content, and keep pace with new technologies and formats to ensure that their collections are accessible.  It’s encouraging to see them in action, and their efforts stand as a potential framework for other organizations in a similar bind to model their initiatives after.

Previously in this series, I focused on local storage; primarily, hard drives and similar media were discussed.  But a lot has changed since that last article was posted!  In particular, flooding in Thailand threatened to severely restrict the supply of hard drives, and retail prices had doubled and nearly tripled for the most common capacities and models.  Pricing for hard drives has begun to stabilize, but supplies are still constrained, and the situation is not expected to go back to anything resembling normal until March 2012 at the earliest.  For you and I, this means that the price of a hard drive, or even a new computer, might bit higher for the next few months and harder to come by, until the region can recover and production of hard drive components can resume.

And so, it makes sense to look at other solutions for backup strategies, with cloud storage being a lead contender.  Cloud (or online) backup services have become quite popular over the last few years.  They offer an attractive option for keeping your stuff safe: for a fee, you get the ability to send your files to a remote datacenter, where maintaining the storage and hardware required for backing up all of your data becomes the responsibility of the backup service you subscribe to.  They upgrade the hardware when it needs to be upgraded.  They fix and replace hard drives that go bad. The idea is to further simplify the backup process so that even buying hard drives and hooking them up to your computer aren’t part of the equation.

An External Hard Drive: the easiest method for making a quick copy of your important stuff. Photo taken by flickr user Miss Karen

All, right, so you’ve heard it over and over and again, and you know it’s true: you need to make regular backups of your stuff. But how?  What options do typical computer users have?

In the past few years, the options for preservation and backups have expanded quite a bit, giving users an enormous array of solutions to choose from.  Of course, the diverse options can be confusing: what’s the best choice for you?

The backup options out there can be grouped into two major categories: local storage and cloud storage.  Each has their strengths and weaknesses, and will appeal to different users based on where and how they use their computers.  Some of the best and most secure backup strategies make use of both solutions… a backup-of-the-backup, so to speak.  I’ll discuss that further in a later write-up.

In this article, I’ll talk about local storage.  In the next article, we’ll go into cloud-based solutions.

A hard disk drive with damaged platters, caused by a head crash. The data on this drive is not recoverable.

Whether we like it or not, those of us who rely on electronics to get our work done are guaranteed one thing: a data loss event.  This means that at least once in our  lifetimes (and sometimes more than that), every one of us who uses a computer, laptop, tablet, smartphone or similar device is going to one day stare at our screens and realize that the piece of information we expected to be there, just isn’t.

It can happen any number of ways.  Sometimes, we users make a mistake and accidentally erase something we shouldn’t have… or someone else might’ve accidentally deleted something of ours that they shouldn’t have. Other times, it’s the computer’s fault: buggy software might’ve claimed to save something but didn’t, or a 10-year-old hard drive finally decided to give up the ghost.  And sometimes, acts of nature (power outage, natural disaster, or other events beyond our control) will intervene and cause vital work to be lost.

Of course, we’ve all heard it time and time again: to protect your documents, photos, drawings, artwork, and other important data, you need to have backups.  Unfortunately, while we all have heard this before and know it to be true, we don’t always follow through.  In the past it’s been tedious to do regular backups; a chore we all dread.  And so, it always falls but he wayside, and often, we get back into a backup regimen only after something bad has happened, and it’s already too late.

But take heart.  A lot has changed recently.  There ARE personal backup solutions out there that are surprisingly easy… and even automatic!  keeping your stuff safe doesn’t have to be a tedious chore anymore… as long as you’re willing to invest a little time and effort at the beginning, and in some cases a small amount of cash on an ongoing basis.
