During the archiving process, you must specify the media type for the archive data (fixed or removable). Removable media include data CDs, DVDs, Iomega Zip disks, and USB Flash drives.
When using removable media, specify a maximum size for the archive that is no greater than the capacity of the media. A typical writable CD can store up to 650 MB of data. DVDs can store up to 4.7 GB on a single-sided DVD, and 8.5 GB on a double-sided DVD.
