In the event of a disaster such as a fire, flood, theft, accident, malware attack or hardware failure your computer can be easliy replaced if necessary, but the data on that device such as photographs, documents, emails etc is not so easily recovered.
Backing up is the process of duplicating this data so that it still exists should the original be lost.The backup strategy that you use will depend on a number of factors, such as the amount of data to be backed up, the sensitivity of the data, how often the data changes, the value of the data etc.
Please get in touch to discuss your individual requirements.
Back Up Hints and Tips
DO NOT back up your data to the same drive that it is already on, even if it is a different partition. If the drive fails you will lose your original data AND your backup.
DO test your backup regulalry by using it to recover some data. A backup is only a backup if you can restore from it.
Don't rely on USB memory sticks for long term backup - they tend to be flakey and will let you down just when you need them most. If you do use them for back up purposes, have several and alternate between them so if one fails you will have others to fall back on.
Do have more than one backup - you can't have too many and try to use a mix of backup media e.g a daily backup to the cloud supplemented by a weekly backup to an external hard disk.
Don't keep your backups with your computer - the disaster that destroys your device could also destroy your backups.
