Setup recurring automated backups
How often should the backup be taken will depend on how often you make changes on your website. Daily changes will require daily backups and then you might only need to back it up once a month in case you make monthly changes and updates on your website.
Bear in mind that there is no need to keep an infinite number of backups – the latest 3-5 will do. Those backups tend to be quite large and there is really no need to keep a backup from a year ago when you have a fresh one from last week.
Know where the backup is located
In case of an emergency that can be solved by a good sound backup of the website, it is key to know where it is located. It is usually in some folder on the server – but which? Know the location and you’ll save a lot of time and effort.
An even better option is to keep the backups off-site. This would mean those are saved in a separate location then your website and this is key in case the server you are using faces hardware malfunction that might compromise both the site and the backup.
