Can you imagine going to work one day and finding your trustworthy computer not working?!! Backing up files is different to saving files. Back up is the process of creating duplicate data. A back up copy of your folders is not entirely secure unless it is properly stored. Saving a file keeps it on your computer for future use or reference.
Regular computer back ups help prevent the panic related to data loss nightmares. These steps should help you decide which files you need to back up and when:
Data loss can occur for reasons such as:
CD ROMs. Blank CDs are not very expensive and are simple to use for back ups. I personally prefer the re-writable ones because you are not wasting CDs with every back up. You can just overwrite the old back up with the most recent one.
DVDs are very convenient for back up as well. They are more expensive than CDs but you can copy a large amount of data to a DVD. CDs and DVDs are vulnerable to scratches, so take care and make two back up copies if necessary. You can also get DVD-Recordable (DVD-R) and DVD-Rewritable (DVD-RW) drives. Most computers these days come with the DVD-R and DVD-RW drives built in.
Network Server. Many companies have an automated back up set up for all the computers in the office. The files are stored to a central server at regular intervals and the consolidated back up is then saved to a removable back up disk.
External Hard Drive I find this option very useful for small businesses and self-employed professionals. You can buy an external hard drive for under £50.00, connect it to your computer and back up your files on it. But you must remember to take it to a safe place, away from your computer to protect the data. Some people take the external back up drive home from work every Friday.
Tape Drives. I used to work at an organisation where tape drives were used for back up. They are cassette-type cartridges that are tried and tested. They are fast and versatile. Storage capacities for these start at 1GB, and go beyond 60 GB. However, the tapes can wear out eventually.
Zip Drives. Not many people use Zip drives these days as CDs are a more convenient option. Zip disks are sturdier than CD ROMs but relatively expensive when compared to CD ROMs. Zip disks are good for moving stuff around rather than storage.
Online Backup. There are also various online backup solutions available. You can purchase an amount of space for a price.
