All too often people forget to do a backup of their files and documents and only realise when something goes wrong and they need to reinstate it all. Backing up your files and documents is vital when using any sort of technology as all technology is prone to problems and you may find that you lose everything in an instance.
If you have your website hosted by a third party, they are likely to do backups for you. As a web developer you need to check how often these are done and if they are automated or you need to do it manually. If you host a website on your own server then you will need to organise backups of site files and databases.
When backing up files and folders from a laptop for example you need to make sure that the device you are backing up to is firstly large enough to accommodate the files and documents and that it is reliable. It is advisable to always have two backups if possible, in case the first one should fail, you have another means of accessing the data.
Portable hard drives are often a popular choice for creating backups as they are easy to use and provide fast, efficient storage solutions. 1TB portable hard drives start from £65 upwards.
