Your main concerns should be: • Have you got a copy of all
files you should have? • Have you really got
very latest version of each of those files? • Was
data transferred from hard disk to storage media without error? • Is
integrity of
storage media 100%? It only takes a scratch on a CD or a kink in a tape to render a lot of data unreadable and thus unrecoverable.
Finally,
catch that few people ever think about until too late. Let's say you have an important file that gets updated periodically, a spreadsheet for example. Let's also assume that today someone accidentally deleted some cells or made a significant error in that file that was not caught at
time. The file is saved and you take a backup. This goes on for a few days — edit, save, backup — before
problem is noticed. What now? Of how much use will your backup be? Even if you are making redundant copies, how far back can you go to recover a pre-error copy of
file? For most small businesses
answer will be from zero to a couple of days at most.
OK, I could go on and on with examples of
problems you can face even if you are making backups, but it's time for some answers.
Look, this is
Internet age, right? If it wasn't for
Internet you wouldn't be reading this, so I know you are connected. Further, if you are in business you probably have a broadband connection. The Internet connects you to "the world". Look at it another way: In backup terms,
Internet connects you to off-site servers. With
right accounts and services it connects you to off-site storage. And it's those special services that are available to you that will make all
difference.
In my small office I have two tape backup drives, a couple of USB drives, several CD burners, floppy and LS-120 drives, external hard drives and networked computers. That's a lot more storage options than most small businesses would have. For long-term storage of files that I may never need again, but which I have to keep anyway (e.g. accounting records), I burn to CD. For everything else I backup to "the Internet".
That's right. I've got tape drives and tape backup programs and I never use them.
My backup is scheduled to take place in
evening after I have finished for
day. It is 100% automatic and requires no initiation from me. None at all — no swapping tapes, no inserting CDs, no anything else. It backs up any file that has changed since
last backup. Plus,
backup system keeps
ten most recent versions of every file backed up during
last 90 days.
No capital outlay. No extra hardware. No media to deteriorate and need replacing. No need to "remember" to take some action.
Online backup services are not all that new, but finding one that is extremely reliable, very easy to use, very affordable (even for an individual home user), and requires no term contracts is not at all easy. Here's
service I have been using for over a year now: http://www.DataSafetyCenter.com
You really have to try this. There's a 15-day Free Trial, after which you are invoiced each month in advance for
coming month, and you can quit at any time. This is
ONLY way for individuals and small businesses to ensure reliable recovery of data with minimum cost, minimum risk and minimum effort.
Oh, and in case you're wondering what happens if
data center itself suffers a catastrophe … each day
data you have stored at
center replicates itself to another data center in a different geographical location.
In under half-an-hour you can put backup problems behind you forever. Or … you can wait for Mr. Murphy to come calling. You already know he only visits at
worst possible time.
