Over time, businesses have used a variety of mediums for data backup purposes, such as floppy disks, CD-ROMs, mini discs (MDs), DVDs, SD cards, SSDs, and USB flash drives. It is also important to consider the best place to store a data backup. Storing Data BackupsĬhoosing a data backup type is just the first decision that businesses must make as part of their business continuity plan. This allows businesses to access files in the destination without using a restore feature. In other words, the destination becomes a “mirror” of the source. While other data backup types collect folders and files being backed up in a single compressed file, a mirror backup keeps each file separate in the destination. One of the biggest benefits of a mirror backup is that backup files can be easily accessed using simple tools like Windows Explorer. Mirror backups are most commonly used to create exact copies of backup data. Files in a mirror backup can be compressed and encrypted individually and only the most recent file version is preserved. Mirror BackupĪ mirror backup is essentially the same as a full backup, with one major exception. However, they do allow for a faster restoration time. The biggest drawback to differential backups is that they require more space than incremental backups. With differential backups, businesses can restore data faster than with a full backup as they only require two components: the initial full backup and the most recent differential backup. A full backup is performed first and then subsequent backups are then run to include any changes to folders and files. This type of data backup involves backing up business data that was created or changed since the previous full backup. Differential Backupĭifferential backups have components of both a full backup and an incremental backup. Restores are a little more complicated than with other backup types as all backup sets, including the first full backup and succeeding incremental backups, are needed for restoration. Of course, there are some disadvantages of using an incremental backup. Incremental backups need the least amount of storage space, but they must be managed separately during the recovery process. Incremental backups are known to be lightning-fast as they are only required to store changes made since the last backup. All succeeding backups are designed to only store changes that may have been made to the previous full backup. With an incremental backup, only the first backup is a full backup of business data. However, a full backup is generally the most reliable copy. Businesses that run a full backup are at risk of overloading their storage space, impacting backup speed. There are many benefits to choosing a full backup, including a relatively short timeframe for the restoration of important data.Īlthough a full backup is the most comprehensive approach to data backup, it does come with certain downsides. Full BackupĪ full backup is the most complete type of data backup where all of the selected data is cloned and stored, such as all files, folders, hard drives and SaaS applications. The four main types of data backup include a full backup, incremental backup, differential backup and mirror backup. There are several different types of data backup systems that organizations rely on to protect their company and avoid data loss events. Having a data backup system in place helps reduce downtime and allows businesses to recover their files quickly and effectively with the least impact on finances and productivity. Data backups are an essential component of disaster recovery that helps restore valuable computer data following a catastrophe.
