Carbonite is an online backup service, available to Windows and Mac users, that backs up documents, e-mails, music, photos, and settings. It is named after carbonite, the fictional substance used to freeze Han Solo in ''Star Wars: The Empire Strikes Back''. It was the first such service to offer unlimited backup space for a fixed price.〔(【引用サイトリンク】 Carbonite Review )〕 Previously, all online backup services were priced by the gigabyte; many other vendors have since changed to an unlimited model. Carbonite offers two separate lines of products: Carbonite Home and Home Office for individuals, families, and one- or two-person businesses; and Carbonite Small Business for businesses with three or more computers. Carbonite was named "Best Windows Backup Tool" by Lifehacker, "Labs Winner" by PC Pro, "Editor's Choice" by NextAdvisor,〔(【引用サイトリンク】 Online Backup Service Reviews )〕 Hottest Boston Company by Lead411,〔(【引用サイトリンク】 Lead411 "Hottest Boston Companies" awards )〕 but received only "two mice" in a MacWorld review putting it second to last. ==Product details== Carbonite Online Backup installs a client software program (Windows and Mac operating systems only, Linux-based systems are not supported) on the user’s computer that operates continuously in the background. This client software automatically seeks out new and changed files on the user’s computer and backs them up using incremental backup. Each file is compressed and encrypted using a 128-bit Blowfish encryption before it is sent to remote servers at the company's data centers via the Internet. (This of course requires that the user's computer be continually connected to the internet, and the speed of the internet connection will impact system performance.) Data is transmitted to the servers using a secure SSL link. The encrypted files are stored on 15-drive RAID 6 storage arrays. The client software also provides de-duplication at the bit level only. Thus files moved to a new drive will be backed up twice. The program is designed to automatically back up user-generated content including text documents, spreadsheets, financial documents, photos, music, etc. Specifically, on a Windows PC, Carbonite backs up everything in the Documents and Settings folder, including the desktop, favorites, and all other files except for temporary, log and video files. Any file or folder can be added to the default backup if it is on a local (internal) drive formatted with the FAT32 or NTFS file systems. (According to the Carbonite website, the Home version will only backup internal drives whereas the HomePlus and HomePremium versions will also backup external drives.) The backup software integrates with Windows Explorer, adding green dots to the file icons of any backed up file.〔(【引用サイトリンク】 Test and Review of Carbonite Online Backup )〕 Adding or removing files from the backup is done using the right mouse button and the Windows context menus. The Windows version of Carbonite will keep multiple versions of backed up files.〔(【引用サイトリンク】 Restoring Previous File Versions )〕 Carbonite can recover from some forms of Ransomware〔(【引用サイトリンク】 CryptoLocker / Crypto Virus )〕 but this requires contacting Carbonite customer service. For Intel-based Macs running Mac OS X 10.4 (Tiger) or 10.5 (Leopard), Carbonite is controlled through System Preferences and using the contextual menu. File systems supported 'by default' on Mac OS X are supported by the Mac client with the exception of FAT. Note that Carbonite is not fully compatible with Lion, consuming around 100% CPU during backup. The program also includes a remote access application that allows individual files to be downloaded to any computer using a web browser. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Carbonite (online backup)」の詳細全文を読む スポンサード リンク
