5 Backup Strategies for students
Ever since the student was invented centuries ago the worst thing that could happen to him was he could lose his notes and this is just as true if the student is using parchment and quills or solid state drives and the latest ultra portable laptop. He needs a way to keep track of the files he has and a good way to back them up. This used to be a massive undertaking in the days of hand writing notes (and I still look at my overflowing lever arch files and decide that I’m never going to copy them out again) which became only slightly easier when the photocopier was invented. The computer, however, revolutionised copying in a way which can (and has) give a music exec the cold shakes and it’s now so easy to keep multiple copies of every file you use that it’s no one’s fault but your own if you don’t use the same logic on your work as your music collection. The only problem for someone wanting to protect their files is picking which method you want to use*.
The best method
This is your humble author’s best bet for simple file protection while you’re at university:

There’s a lot of sense in using these small, inexpensive devices to store your data while you’re studying. They are extremely portable, not only between locations but also between computers. I could plug my USB stick into a university lab computer, hand it to a print shop or plug it into my own laptop and the files on it can be read off with no problems or issues whatsoever. I often copy files that I wanted printed copies of to my USB stick so that I can print them off on the much cheaper bulk laser printers in libraries than on my inkjet at home.
It depends on your requirements, obviously, what you need but generally I would go for a stick with a capacity of a few gigabytes. There’s really no reason not to do this now because costs have dropped so much. Fancier models are nice but speed and security are often overpriced in the eyes of users who just want a plug and play flash drive. I picked my 8GB stick off Amazon.co.uk for about ten pounds. An 8GB stick will be effectively limitless as far as your homework is concerned. I keep a great deal of information on my USB drive, case reports, journal articles, coursework, etc but try to ensure that there is no personal data on the stick, just in case I leave it lying in the library or have it stolen from me and 8GB goes a very long way when you are using it to store text.
I use a [Windows briefcase (remember those?) on my flash drive which will sync with my home computers with a single click. The Briefcase is an ancient feature in Windows since Windows 95 but one which proves very useful to me nearly every day.
For other people simply dragging the folder over will be more than enough to keep a copy of your work but it lacks the synchronization features that using a Briefcase (or another sync program) will give you.
The online method
Online storage is a relatively old phenomenon but one which has only recently taken off. While people have had the opportunity to store their files remotely for many years the tipping point has come when it became easy and fast to do so. While people who still have dial up connections will gladly tell you how slow it is to browse web sites this is nothing compared to the ~3kb/s effort of sending a substantial amount of data the other way.
The most common domestic Internet connection is the Asymmetric Digital Subscriber Line (ADSL) which divides a phone line up into various bands for upstream, downstream and voice. This allows the connection to do all three operations at once. That’s great for being able to answer the phone at the same time as use the internet but the way that the phone line divides up the data frequencies does not divide it equally – it’s asymmetric. Generally people will have hugely quick download speeds and considerably slower upload speeds, maybe as little as 10% of the download speed. This provides a massive barrier to anyone who wants to send a lot of data across their connection because it simply takes a lot of time. For smaller amounts of data, though, it’s very convenient.
There are many options for online storage:
The handiest application I’ve found for my online storage has to be the Gmail Drive. This shell extension for Windows allows you to mount your googlemail account as a drive in Windows and copy files to, save to it from programs and generally use it as you would any other drive. The only difference is that the files are saved in your Gmail account as attachments in emails which you can access from anywhere you have Internet access. The storage limit is about 8GB and no single file can be more than 10MB but if you only use it to back up your text file homework and notes this is more than enough. You may have to reduce the length and complexity of file names to get it working just right but that’s a rare issue for most users.
You could do this manually by emailing yourself files as attachments which will let you access them from wherever you have Internet access but the drag and drop of Gmail Drive is particularly convenient for me.
A slightly more involved method is simply to use an online storage provider; these can be free but often charge monthly fees for their services and provide gigabytes of easy to access storage which you control through an often very colourful and polished downloadable application. I find these to be too much for my requirements which are served by not much more than an email account but they are a good, easy to use option for people who don’t want to get too involved in the technical background.
The network method
If you have more than one computer in your house, for example I have my work laptop and I have a more powerful desktop computer that I use for games and other entertainment tasks, you can use them to store your data in more than one place and improve the redundancy. I personally use a simple Windows SMB based network to create network shares that I can mount and use as regular drives and that does everything that I need the network to do, backup wise.
Even if you don’t have another computer you can still use a network to back up your data. Most people on broadband connections use a router to connect their computer(s) to the Internet and the router is a device which is naturally good at connecting lots of devices to networks. The standalone option is a NAS device:

Network Attached Storage is a previously only business technology which suddenly became considerably cheaper and suddenly a lot more economical for the home user. These devices are roughly speaking specialized, low cost computers that have enough power to control a hard disc and a network connection and some have features like automatic Bittorrent downloads, which allows the device to run all day and night and not tie up a “real” computer. They come in two main varieties – prebuilt and barebones. Barebones units tend to be a cheaper purchase (but there can be a premium once you factor hard drives into that price too) than complete versions but you have to provide your own hard drives but that gives you flexibility as to your capacity. Prebuilt versions already have drives installed and generally arrive at the user ready to be plugged in the wall and used.
The sneakernet method
Sneakernet [sic] is a term that describes when instead of electronically connecting two computers you save the file you want to share to a disc and physically take it to the other computer. This is useful in situations where you want to save a copy of your work for future reference and want it to be safe from hard drive failure or being stolen from you while you’re out. It is not a bad plan to burn coursework and other essential pieces of your own work to a CD so you can store it at home if the worst should happen. Given the size of coursework files you could get a sizeable portion of your entire written handiwork stored on an old school floppy disc, I certainly remember family members finishing their entire university career with a small stack of floppy discs tucked into their notes. Those discs will still faithfully hold the files that were put on them in years past and that’s all that can possibly be asked of a backup.
No matter what method you use, remember to do it often!
Backups are of no use to you whatsoever if you haven’t got a recent copy of a file that’s suddenly disappeared. If you leave your backups for too long you risk running into a situation where the copy you have is not one which can really help you. I personally keep my USB drive nearly perfectly up to date because I keep the USB drive plugged in a lot of the time and it’s a moment’s work to click “Update All” in My Computer when I’m finished working.
Try to get yourself into a habit of backing your files up regularly when you’re working so you’re not left with outdated copies when disaster strikes.
Hopefully habits picked up in university with stay with you throughout your professional life and in an era where data losses seem to occur on a weekly basis you will be the professional who knows to keep a redundant copy of your client records locked up in a safe place and to use encryption (more on this later) on data that goes out of the office.
*If you’re particularly fervent in your quest for data protection you can bear in mind that the protection that backups give you is redundancy and the only thing that using more than one of these systems can do is improve your security. I personally have copies stored on both my computers as well as on flash drives.
