To avoid losing important data - back up regularly !
In simple terms "backing up" is making a copy of the important data stored on the computers' hard disk , and storing it on a removable disk, such as a DVD, CD, floppy disk, zip disk etc.
Why backup your data?
Making regular backups means that you can restore your data in the event of hard drive failure, or other unforeseen event. Data stored on a computers' hard disk drive is always at risk, as hard disks can fail without warning. In addition, files can be accidentally deleted or corrupted. Remember computers can be replaced, whereas your data could be lost forever !
1. Decide what you need to backup.
See some suggestions below:
- Irreplaceable family / holiday photographs.
- Your CV and copies of important letters, and emails.
- Downloaded files (programs, music, updates etc
- Accounting, payroll data, and customer data.
2. Organise Your Files
By storing files in logical categories in the same location you will make things much easier when locating your files for back up.
3. Choose a suitable backup device and media
Your choice of backup device will depend on the amount of data you need to backup.
- CD / DVD Rewriter
- Zip Drive
- USB Thumb drive. (shorter term storage)
- Floppy Drive. (only suitable for small files)
- External Hard drives (prone to failure)

When to back up your data.
The frequency of backup depends on how much data you add to the computer, and how important that data is. There are many backup programs on the market that can automate the backup process, the backed up files are usually compressed to save on storage space.
Always label backup disks, this will make restoring data more efficient. Always check your backup disks to ensure the data has been properly saved. Always store your backup disks or tapes in a safe place, i.e. not in the computer.
