Get those pictures off that camera!

Do you keep your pictures on your camera, and never copies them to the computer? History has countless examples of loosing the first years of their child, the pictures from their honey moon or other important pictures. The camera may get lost, stolen or damaged along with all of the pictures.

If nothing else, make it a habit of copying them to the computer every month or so.

Backup: Help your mom

When visiting your moms house, she may not have backup and may not be able to make one. Help her out: Just make a copy of her pictures, documents and e-mails onto a USB stick and keep the data under your backup solution. It may not be updated that often, but when her computer fails, it is better than nothing.

NAS friendship

If you have a friend that has a NAS box of the same brand as yourself, you can often set your boxes to synchronize with each other over the internet. This is a very cheap way of getting an offsite backup.

Just note:
  • You must trust your friend, as he may see all of your data.
  • You should not set your boxes to synchronize everything, if you have movie or music collections. It will use all of your band with and may break copyright laws.

What is a NAS?

NAS is short for Network Attached Storage. Usually it is a box running RAID1 or RAID5, which can be connected to your network and looks like a shared network drive. Then you can access it from any of your computers.

Very often the NAS has a lot of extra features built in, such as photo sharing, bittorrent download, iTunes support and more. If you have multiple NAS boxes of the same brand, your can often set them up to synchronize with each other. This can be used to creates a cheap and automatic offsite backup.

A NAS is a very easy way of running RAID and at the same time get easy access to your data.

How does it fail: CD/DVD/Blue-Ray

Optical media is still a popular form of backup, and for a good reason: It is cheap and lets you keep the copy "forever". But what is that? In general you should not count on a burnable optical media to last for more than 5 years. The chemistry is changed all the time, and the media are made for practically no money in all sort of far east countries, so you really does not know what you got.

The most common ways to destroy optical media is time, sunlight, heat, moist and scratches. Keep it dark, dry and at a stable temperature, and it will last longer, but don't count on it.

How it fails: Online and cloud backup

Online backup, often named by the buzz word "cloud", is when you have a program upload your data to a company that will keep it safe. When you needs the data you can download it. This is very easy because the program pretty much takes care of itself, and you get a real offsite backup.

This sounds perfect, and when something does that you can know it is not:

  • Companies goes bankrupt - online backup companies does too and even though your data exists the servers are turned off.
  • Data loss - all the usual ways of losing data applies to these companies too. They may have better safety but not 100%.
  • Got a new credit card? And did you forget to update the number with your online backup? And maby the contact e-mail address was outdated. You might not notice untill it is too late.
  • You lose the password or encryption key for the backup, you lose it all.

By the way: All of these scenarios has happened within the relatively few online backup has existed.

Online backup or cloud backup

With todays fast and cheap internet connections it is very popular to make a backup to "the cloud". It usually works like this:

  • The backup company provides a program which you install.
  • You tell the program what to backup and lets your computer run until all of the data has been uploaded.
  • From now on the program will only upload the data that changed, which is usually very little.
One thing to look for, is if the company has a separate restore price. When you have lost your data, it is not fun to find out that you must pay a horrible rate to get your data back. Restore should be part of the subscription.
