With the recent advancement of HD content, storage requirements are becoming aggressive and require higher networking bandwidth than ever before. Disks are getting larger and cheaper but most modern consumer computer devices don't have enough internal storage to handle all of our requirements when it comes to photos, music, video, documents, etc.; and, to make matters worse, on a daily basis I use three to four different computers, all of which require backing up in case anything should go wrong.
Right now reliable, safe, long-term data storage means having multiple, redundant disks on the network - which can be a considerable cost. Our home requires somewhere in the vicinity of 2-4TB of storage to handle everything comfortably, with some room for growth. Whilst this is not a lot of storage in today's terms, any future-proof device would still be quite large, noisy, hot and have a low spouse acceptance factor.
So, what's the answer?
Cloud computing and storage has always appealed to me and have reached the point where they're just as good, if not better, than local alternatives.
The home network will always require some local storage. Home broadband hasn't yet reached the level where everything can be streamed from the Internet as an on-demand service - not in the UK at any rate (and certainly not in the US or Australia). So, a local 1-2TB, low-power NAS for
transient video data is still required and, because of the nature of the content, backups aren't required.
Music is roughly in the same camp. Since most of the music is synchronised with a portable music player, in the event of an disaster, a simple re-sync should be sufficient.
Photos are a tricky call and one that I've had to take quite a firm stance on. Typically, when taking a bunch of photo only a few are ever really any good and worth showing to people. What do we do with the rest of them? They usually languish in a folder somewhere getting pushed from computer to computer, medium to medium without ever being accessed again. So, I say, get rid of 'em. The rest should be put into the cloud for sharing with the rest of humanity. Flickr, PhotoBucket, Picasa... take your pick. Let them worry about the storage and bandwidth.
Documents are fairly easy. There are plenty of services out there that will do simple, cloud-based file storage sitting on top of Amazon's S3 or Rackspace. Again, take your pick and get them off your local disk.
If you take this approach it becomes fairly obvious that your local PC, laptop or tablet (hello,
iPad!) becomes a commodity device as it simply consists of an OS and a bunch of applications that allow you to access the cloud and your content. Nothing of consequence is ever stored locally. It also means that you become free and untethered to a particular machine or environment.
So, what happens if the cloud disappears?
First of all,
all of The Cloud would have to disappear at once, which is unlikely. Secondly, you can always backup your data. There are services that offer backups of your cloud-based content.
Backupify are an example of such an organisation. Their restore and export procedures are not yet complete but their experts will help you out should the worst happen.
As a geek I also tend to have a slightly above-average set of requirements when it comes to the Internet; all of the above as well as running a blog, a micro-blog, having several domains, source code repositories, etc. all of which have to be hosted somewhere. Previously the sensible option was to host these myself. However, recently I've come to the conclusion that out-of-the-box software (such as
Wordpress & Google Mail) do a pretty good job as they come and no longer require me to install, configure, upgrade and maintain software -- leaving me with more time to do other things.
Not only have I save myself some effort but I've also saved quite a bit of money, as a majority of the cost before was running a server. The cloud now provides a plethora of services for free (usually subsidised by advertising) that have relatively low-cost upgrade paths also providing scalability, should you need it.
The following table is a simple side-by-side cost comparison for the content that I was hosting myself previously versus the cost, today, of utilising cloud technologies:
Not bad, eh?
I still, however, have some concerns about turning all my data over to the cloud. Will these companies disappear one day, without a trace - taking my data with them? Possibly. Will the data be backed up somewhere? Maybe. Will I be able to access it? Probably not.
These questions are unanswerable right now and only time will tell - but I really can't think of a better way of doing it, today, without having a vast, "expensive" storage array at home. Hopefully, someday soon, there will be a breakthrough in storage technology and I can store my ever-growing digital life safely and locally, somewhere that I trust. But, if that does happen, you can be sure that content generators will find a way to use it -- resulting in an arms race again, pushing the limits of storage technology ever forward.
I do, however, feel lighter for having made the move.
