“If you should go to Phoenix this week-end and have any spare time, you would probably be interested in seeing a demonstration of the DITTO machines,” he encouraged Miss Anne Raymond, “so that when we can afford to buy a duplicating machine we will all be familiar with. Carbon Copy Cloner (CCC) is a Mac OS X application that can be used for creating file backups, complete images of your computer, or for cloning hard drives. Evolving Media In The Digital Age As computers have gained an increased role in our lives, the need for safely storing digital memories has grown to be more important than ever. Three years later, he was encouraging one of the teachers who worked for him to take a look. Using Carbon Copy Cloner is a little more involved than Time Machine but the benefit of making an exact, bootable duplicate is well worth the extra effort. His portrait was drawn and mimeographed by a representative of the Ditto Company, presumably at the 1932 National Education Association (NEA) conference in Atlantic City, New Jersey. A fabulous example of this process was found in the records of the Principal of Schools for the Fort Apache Indian Agency, George E. The Ditto, unlike the carbon copy - typed document, could quickly transmit hand-drawings onto worksheets and school flyers. People of a certain age will remember the delicious smell of the copy room at their school that came courtesy of the Ditto machine (a distinct combination of methanol and isopropanol).
For example, if your Time Machine backups are currently running and backing up to a disk image, CCC will not be able to copy the disk image file, rather it will get an error that the files are in use.Daily, archivists who deal with Twentieth Century collections come into contact with the remains of duplicating processes past: carbon copies, thermofax, early xeriographic copies, and a personal favorite of our director, the mimeograph, or “Ditto.” Lastly, please note that no application can access the contents of a sparsebundle disk image file while that disk image is mounted or otherwise deemed to be in use. Other items in this folder on the destination will be protected from deletion. Further, CCC will only consider sparsebundle images for deletion in a Backups.backupdb folder on the destination. local Time Machine backups will be excluded. Note that the only items in a Backups.backupdb folder that CCC will copy are sparsebundle disk images. Back up only an individual folder, or an entire external hard drive. from CCC's Source selector and choose the Backups.backupdb folder directly to configure CCC to back up the sparsebundle disk images. You want options, and CCC has them Create a backup on your external drive or back up your files to another Macintosh. If your source volume has a folder by that name, and you want CCC to copy sparsebundle disk images from this folder, you can choose Choose a folder. Note that CCC will exclude the Backups.backupdb folder at the root level of a volume by default.
In fact, CCC quite capably copies only the bands within the sparsebundle that have changed, so you can add CCC to this type of setup for a second tier backup to an offsite network share. CCC can copy these sparsebundle disk image files without any special configuration simply choose your network volume as the source of your CCC backup task.
When Time Machine is configured to back up a Macintosh to a network volume (such as a Time Capsule device), Time Machine stores the backup in a sparsebundle disk image. Backing up Time Machine sparsebundle disk images
Apple does not document a procedure for making copies of Time Machine volumes. No, CCC will exclude the Backups.backupdb folder during a backup task because Time Machine backup folders contain Apple-proprietary filesystem devices.
