Older backups will be deleted to make space for new backups, according to the configured minimum and maximum numbers of backups to keep, and the drive space usage limit.&lt;/p&gt;&lt;p&gt;This system protects your save games in the case that a game crashes or is forcibly shutdown while saving, but NOT in the case that the drive used to store the memory card files is damaged, so this does NOT replace a traditional backup system.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</string>
