Backups are an essential part of your Disaster Recovery plan.
You should ensure that you have good, tested backups which are done on a regular basis. Ideally you should do so daily, which would give you the quickest recovery time as the data is only one day old.
You should also remember the 3-2-1 rule. This states you should keep 3 copies of your data, on 2 different types of media with at least 1 copy of the backup stored off-site.
