  • Optical media, which includes CDs, DVD, and Blu-ray, has been in decline over the last few years, even though it's a good way to back things up, especially for permanent backups. This is because most optical media is designed to be written on once -- there's very low or no chance that information will be overwritten. (Even RW optical disks -- those that allow for rewriting -- can't be overwritten by accident, since you will need erase the entire disk first). Most computers comes with a DVD/CD optical writer (or burner), some even come with a Blu-ray burner, and the media itself is relatively cheap. Generally optical drives offers 700MB (CDs), up to 8GB (dual-layer DVD), and up to 50GB (dual-layer Blu-ray) of backup storage space. Note that writing on an optical drive takes time and during the writing, the computer needs to be left alone to do its job, without performing other tasks, to ensure successful backups.

    On a personal computer, backup storage is commonly achieved with s and DVDs. In an enterprise, backup storage can sometimes be achieved through replication of data in multidisk storage systems, such as RAID; as part of network-attached storage (); as part of a storage area network (); or as part of a system. Enterprise often makes use of both disk and as storage media. Special software is used to manage backup as part of a storage system.

  • In computers, backup storage is that is intended as a copy of the storage that is actively in use so that, if the such as a fails and data is lost on that medium, it can be recovered from the copy. In an enterprise, because the loss of business data can be catastrophic, it is important that backup storage be provided.

    Users can choose to compress and/or encrypt data when it backs up to the cloud; backup history and various recovery options are available. The actual backup process can be set to either real-time or on a schedule, and can be throttled in the event that it's a drag on the company network.

  • Online backup services like create mirror copies of your files, which the app then uploads to the service's online servers. This means that if you change the file, the changes are added to the servers, creating a new version of the file. But this also means that if you delete the file from your computer, the online backup app removes the file from your account, though you generally have a 30-day grace period to restore files before they're permanently deleted. In other words, with an online backup service like Carbonite, your backup storage is limited to your computer's hard drive even if you're paying for unlimited storage. You can't dump files into your online storage account to free up space on your computer.
