Backups! You can never have too many backups.
If the initial location is damaged, like if there was a fire in the building that the computers were stored, then the on-site backups would be lost. For companies with significant amounts of very important data, it is essential that this data is safe. If they have more than one site with computing capacity, then it makes sense to have off-site backups. They could also use a data centre that could host it for them if they don't have a facility themselves. Data backups need to be tested to make sure they work. There are often changes to systems and technology being used, so there is a chance that some of the backups might not work if there have been changes. Regular backups are important for that reason. There is also that there was a problem during the backup that those operating it were unaware of and some data may have been lost or the incorrect data was backed up. So testing is important to find any problems like that.
