As you start to take backups on a regular basis, whether it is daily, monthly, or some other interval, you will notice that the files quickly start to add up. If you are backing up a large site, the storage space you need to keep all of these files available may get out of control. Of course, at some point, you can delete the old backup files with newer ones available to use. It’s not wise to keep only one viable backup file on hand, just in case that file is corrupted or faulty for some reason. For most sites, keeping backup files for two or three months before they are deleted is a good middle ground. That will provide you with plenty of files to work with, yet it will avoid accumulating an overwhelming amount of data that needs to be stored.
