Happy World Backup Day!
Today is World Backup Day, and in this blog post I am going to talk you through the 3…2…1…backup method. The three main methods are optical disc, hard drives and the cloud.
You can Burn your most important data to any optical media such as CDs/DVDs or Blu-Ray discs. All of these disc formats are still very useful and valid today, as long as you have a optical disc drive available. There are cheap external optical disc drives available on the internet, if you are in the market for one.
Optical Disc Size
CD (Compact Disc) = 700MB (Megabytes).
DVD (Digital Versatile Disc) = 4.7GB (Gigabytes) single-sided – 8.5 – 8.7 GB single-sided, double-layer.
Blu-Ray = 25 GB (Gigabytes) single-layer – 50 GB dual-layer – 100/128 GB (BDXL). Keep in mind a special BDXL Re-Writer is required to burn BDXL discs.
To burn data onto a disc of any format, you will need a copy of some software to copy your data to the disc.
Here is a list and comparison of disc authoring software click here. (The link contains software for Windows, Mac and Linux). I would recommend CD Burner XP for Windows users.
Backing up to a hard drive is one of the best ways to store lots of data in one place, as the capacity is much greater than any of the optical disc formats mentioned above. The largest capacity size on the market today is 8TB (Terabytes).
Hard drives are available in two sizes 3.5inch PC desktop size and 2.5inch Laptop size. This means that they are very portable just like optical discs but you get more storage for your money long term.
Unlike optical discs, It’s much harder for a hard drive to be susceptible to the physical elements outside it’s casing and become damaged, unlike CDs or DVDs where they get scratched and damaged by user misuse.
But a hard drive can become severely damaged if the drive is dropped on the floor at a height when powered on, or it gets disconnected by the user at the same time that data is been written to the drive.
To prevent this from happening, always make sure that all data has finished been written to the drive, then completely shut down your PC or Laptop, before disconnecting and or removing the drive from the system, that way no data will be lost or end up corrupt and damaged.
You can also backup your data to a USB drive or SSD (Solid State Disk).
Please note this type of drive media is much harder to recover, due to the fact that it has no physical platter disks and has no moving parts, these have been replaced by flash memory cells which get positively charged when data is written to the drive and therefore the drive cell membrane is damaged overtime, therefore once the drive dies data is harder to recovered. Drive cell membrane aren’t damaged by reads to the disk only.
Here is a list of backup software click here. (The link contains software for Windows, Mac and Linux). I would recommend Windows Backup & Restore for all Windows users.
The cloud is a large group of servers, that are in a remote location which are connected to the internet (Wide Area Network). The server farm stores, manages and processes users data that is uploaded to the cloud.
This makes cloud storage ideal for backing up your most important data which you can’t afford to lose as a result of local drives failing.
An example of cloud storage and services include. Apple iCloud, Google Drive and Drop Box, just to name a few.
It’s also very important that you encrypt all your data before uploading it to any cloud service. By doing this you are guaranteeing that extra level of security. To encrypt your data I would recommend VeraCrypt which you can download here.

In conclusion I have given you the building blocks to develop a solid solution for data backup and recovery. Also making sure that you have copies of all your backed up data in multiple locations physically and in the cloud (Internet).
