From
Mark at Compulogix ... getting IT to work! 
Dear All
This time I want to talk
a bit about backups. It never ceases
to amaze me how often people don’t make backups of any kind. Most of you will
have something on your computer that you would be upset about losing, be it family
photographs or videos, business accounts, that time consuming genealogy
project, letters, CVs, emails or whatever. Now just imagine how you would feel
if you didn’t have those anymore! Doing a backup simply means saving all those
things that you value, so that they are in more than one place. It’s not like
traditional photo’s, videos and documents, where it was usually impractical to
have copies. Things stored on a computer can be copied umpteen times, to
umpteen places easily, so why not do it if it’s easy? The answer is usually
that most people don’t know where to start. Here’s a quick introduction.
Backups.
Essentially, you want to
copy the stuff that matters to you, to a safe place. So once you know where
your stuff is, you just need to
decide where to put it, and how to get it there.
Get your stuff in order – if you never save files and documents to odd places then skip this.
Windows by default
encourages you to keep all your pictures together, your videos together,
letters and music, whatever. Windows XP more or less kept them all together in
one place by default, Windows Vista and 7 likes to separate them by type but
still keeps them largely together. I say that by default Windows keeps stuff together, which means that you,
being in control, can choose to
spread your stuff all over the place. So the first order of the day is to know
where you have put your own stuff. It makes sense really; you need to know
where stuff is in order to back it up. So find it, and if you don’t have a need
to spread it all over the shop, then move it back into My Documents, or My
Music, My Videos etc.
What do you backup to?
I want to be sure that
it is easy for me to regularly save the stuff that matters to a safe place. But
let’s just think for a moment about what we mean by a safe place.
If I copy a picture
called “Holiday001” to “Holiday001Safe” have I made a backup? Well, yes I have!
Is it any good to me? Not really! The only time it is of use to me is I
specifically delete or mess up “Holiday001” in which case I can copy it back
from my copy.
If however, a virus
wiped my computer’s hard disk, or my hard disk drive died, or my whole PC died,
or was stolen, or I left my laptop/tablet on a bus, then I have nothing.
My definition of a safe
backup then looks more like “a copy of all my stuff to somewhere outside of my
PC”
There are two main
options for this nowadays, there is a copy to an external storage drive of some
sort, or there is what’s known as online backup. The online backup is becoming
popular, as it ticks the box with regard to the backup being very much outside
of my PC. However there are a couple of niggles with this that don’t sit well
with me. The first is that I don’t actually have a clue where my backup
actually is? It’s just “on the internet” somewhere. Does this matter? Probably
not! However the simple fact that it is ‘out there somewhere’ in these days
where even the most major corporations are being hacked, makes me question if I
want whatever my stuff is being out of my control. Another niggle is that it
can take ages to put your backup up there. We think in terms of increasingly
fast broadband, but this is fast for bringing stuff to our PC’s, it is normally much, much slower to put stuff onto the internet. If you have videos
and lots of photo’s and music, then I think it becomes impractical, and it can
also become expensive, as you usually have to pay if you exceed a certain
limit, which means you either pay, or you try to make sure you keep your
valuable stuff within an arbitrary size limit.
So for me that leaves
only the option to back up to something attached to my PC. There are 4 main
options, Optical disks (e.g. DVD’s), USB Flash drives, and external hard disk
drives, and finally to another PC. Which one do you use? Well that sort of
depends on how much stuff you have.

Comments |
|
USB Flash Drive (also called a Memory Stick or Pen Drive) |
Small cheap and very convenient. Can carry it around and always have
your ‘stuff’ with you. |
Expensive if more than 16GB, though 32GB ones are coming down in price
fast. Easy to lose! |
Make sure they are big enough to hold all your ‘stuff’, with plenty of
extra space to allow for growth. |
|
DVD |
Cheap. |
Limited in terms of space and reliability. |
You need a software program to manage these, only really good if you
have less than 1 DVD’s worth of ‘stuff’. |
|
Another PC |
Allows you to work on ‘stuff’ on more than one PC |
Easy to get confused regarding which PC has the latest of any
particular document. |
You need to be fairly aware of Networking, or assuming you transfer by
means other than across your Network then you will have already made your
backup – so why bother? |
|
An external Hard disk drive. |
Excellent if you have more than 16GB of ‘stuff’ (or 32GB - see above).
Fast |
People tend to leave them next to their PC. Should there be a fire
then you could lose both your ‘stuff’ AND your backup. |
There are two main forms of these. The cheaper big ones need to be
plugged into the mains as well as the PC. The smaller ones are much more
convenient as they only need plugging into the PC, and are dropping in price
fast. |
|
Online Backup |
Very convenient |
Initially very slow. Can be expensive if more than a few GB. |
Where is your ‘stuff’? You are told it is secure, but is it? |
If it helps 1TB or
Terabyte=1000GB or Gigabytes and 1GB=1000MB or Megabytes – a Song is usually
around 4MB and a photo maybe around a half to 2MB)
If you are using Flash
drives I would recommend buying more than just the one, that is simply because
two allows you to leave one at home and put the other somewhere safe out of the
house or office in case of burglary or fire or some other catastrophe where you
could lose both your PC and all backups. Sorry to be a pessimist, but these
things happen.
Look out for USB3
devices. These are pretty new and are dropping in price quite quickly and are
reckoned to be 10 times faster than USB2 which all recent PC’s will have. It
might prove worth paying a little extra for a USB3 device if you think you are
likely to buy a new PC (or add USB3 to your current one) You need a slightly
different cable for USB3 but you can plug them into a PC with USB2 or using a
USB2 cable and they will work just fine, just slower than USB3!
Making your backup.
OK So you know what you
want to backup – your stuff – and you
now have a suitable device to back it up to. How do you do it? If you are still
reading this then you must be keen, good for you.
There are a number of
ways of doing a backup. This can be the very confusing bit.
Full system backup, incremental backup and just backing up what
you want.
You could back up your
entire system, not caring about individual files. If you like your system the
way it is, and it seems to be working just fine, just back the whole thing up.
This is often called an image backup and is a very sensible thing to do. There
are some great products out there if you want to take this route (I use
Acronis), but it requires a fair bit of time, a lot of disk space, and requires
a bit of understanding to set up properly. Obviously to back up an entire
system, you need sufficient space to hold that backup, and plenty of additional
space to do it again, and plenty of additional space to actually use the computer
day to day. What if you do a full backup and then load in some more pictures to
My Pictures? Do you need to redo the full backup again? Well actually no, you
probably don’t. Most good backup systems allow you to do incremental additional
backups, which just contain the changes since the full backup, or even since
the last incremental backup! This can get confusing to manage, (never mind
explain!) but if you are technically minded and understand the concepts
involved then it is a very good way to go. One other thing about image backups
is that they can be a little confusing to recover from.
Personally I don’t do
this incremental bit. I do make a full system backup after I do anything
significant with my PC, like Hardware or major software updates, but I actually
backup my data (or stuff as I called
it earlier) separately and very regularly.
The full system backup
is great though, as should something nasty happen to the PC it can be restored
quickly to the state it was on the day the backup was made, and then the stuff can be recovered.
You could just use Copy
and Paste or Send To in Windows Explorer to do you backups manually, but this
can be very slow if all you really want to do is to copy new or changed files
to (and optionally remove deleted files from) your backup.
There are any number of
software products out there that make backups simpler, Windows even has its own
– if you are on Windows 7 then look in Control Panel for ‘Backup and Restore’,
or access the Help and Support system and search for Backup.
To go into any of these
is way beyond the scope of this document, but if like me you like good
versatile, free software then you could do worse than to use what I use -
SyncBack Freeware (available from www.2brightsparks.com – nothing to do with
me) It is a little tricky to set up with lots of options, (there is a help file
to get you there) but once it’s done, and your initial back up is made, it
beautifully updates only files that have been created or amended since the last
backup onto your backup device, which means it takes very little time to do
your backup, and making it quick and easy is the secret to doing it regularly,
and safely. It can even do it automatically for you so all you have to remember
to do is connect your backup device.
Whatever you decide to
use, just ensure you do something!
What if it’s too late?
I should quickly say
that ‘stuff’ can usually be recovered from a PC even if your hard disk or your
PC appears to die, so even if you don’t have a backup, if you find yourself in
this position give me a call and I shall see what I can do. For the same
reason, you should be aware that when you throw or give away an old PC, your
stuff may still be found by someone who knows how to get at it. There are ways
to make sure this is not possible.

Thanks for your time;
I hope some of you found some of it useful. If your PC / Network / Internet /
Email / Backup or whatever isn’t running smoothly at the moment, my number is
below, or if you want to ask the odd question or have any suggestions for a
topic for another email or you are finding something particularly frustrating /
problematic on the computer front, why not send me an email.
Kind regards.
