Backup isn’t just about storing copies of your customers’ data; it’s really more about what happens when you need to restore it. You see, the more often you back up, the more up-to-date the data is when the time comes to restore it. Much of this is driven by the backup window, which is the time it takes to perform a backup without impacting system and network performance. Performance degradation is one reason backups are usually done during off- peak hours.
