Backup Strategy

Recording files with a QuickTime Codec makes is super-easy to review the footage on your computer.
Digital media have changed the way we think about image preservation. It used to be unthinkable that an original camera negative would be discarded after the images got transferred to an intermediate storage. Today, we sometimes hear, that the original camera data is deleted from the recording media, once it has been copied and "the copy looks OK".

Since every copy process bears a certain risk that some data is not transferred correctly, we cannot endorse the use of a simple file copy as it is usually done in Windows Explorer, the Mac Finder, or by the cp-command in the Terminal.
If you have to re-use recording media, we think it is mandatory that the copy is verified with a calculated checksum.

Card Readers
You can find several CFast 2.0 card readers (readers/writers) at different price levels. Most of these readers come with a USB-3 interface that can reach around 400 MB/s read speed. The actual performance, however, varies due to different factors, such as the write speed of the target medium.

ARRI offers a CFast 2.0 card reader that is manufactured by our technology partner Codex. The card reader features a spring-loaded card slot so the CFast card cannot accidentally be pulled out when the reader is moved around. The electronics sit inside a robust, diecast metal housing with a rubber bottom plate, which gives the reader a tough shell and a secure stand.

Note: The Codex CFast 2.0 card reader is compatible to Mac or PC computers with a USB 3.0 or USB 2.0 connector. We recommend at least Apple Mountain Lion (OS X 10.8) and Windows 8, as these operating systems offer native USB 3.0 support. Older operating systems, may require installation of a third party USB 3.0 driver.

Copy Tools
You can find different tools that will quickly transfer camera footage to one or more backup destinations and verify that each copy was written without error. The basic function always is a verified file copy. Depending on the software, you may also be able to keep track of file locations and clip metadata, to create detailed reporting or to access quality control features. Some of these tools can be upgraded to offer transcoding (e.g. for rushes), LTFS control (tape archive) and EDL conforming, which gets important once you have to access original camera footage that is spread our over several backup drives or tapes.

Here are a few examples of software tools that you should take a look at. Since all of them are continuously improving, we'll only give you the name and address, so you can look at the details on their websites:
