156 • OnStream’s ADR (Advanced Digital Recording)—The newest technology aimed at desktop and small network backup needs, featuring capacity up to 50GB@2:1 compression Other tape backup standards, such as DLT (Digital Linear Tape) and 8mm are used primarily with larger network file servers and are beyond the scope of this book. Travan Tape Drives and Media Imation created the Travan family of tape drives to provide a standardized development from the crazy-quilt of QIC and QIC-Wide MC (minicartridge) tape drives that stemmed from the original QIC-40 and QIC-80 drives and their DC-2120 cartridges. Note that Travan-1 through Travan NS-8 retain read-only compatibility with the QIC-80 cartridge. Table 5.10 Travan Family Cartridges and Capacities Read/Write Travan Cartridge Capacity/2:1 Compatible Read Compatible (previous name) Compression with with Travan-1 (TR-1) 400MB/800MB QIC-80, QW5122 QIC-40 Travan-3 (TR-3) 1.6GB/3.2GB TR-2, QIC-3020, QIC-3010, QW-3020XLW, QW-3010XLW QIC-80, QW-5122, TR-1 Travan 8GB (Travan 4GB/8GB QIC-3095 QIC-3020, QIC-3010, 4/TR-4) QIC-80, QW-5122, TR-3, TR-1 Travan NS-81 QIC-80 4GB/8GB QIC-3020, QIC-3010, Travan NS-20 10GB/20GB Travan 8GB, QIC-3095 1. This cartridge is replacing the Travan 8GB (TR-4); a single cartridge can be used on either NS8 or TR-4 drives. Future developments might include an NS-36 model. Note Chapter 5—Floppy, Removable, Tape, and Flash Storage Backward compatibility can vary with each drive; consult the manufacturer before purchasing any drive to verify backwardcompatibility issues.
Proprietary Versions of Travan Technology Ironically, since Travan technology was designed to bring an end to the QIC MC/QIC-Wide tape “wars”, some drives exist that use proprietary versions of the Travan standard. Non-standard sizes include • 5GB Tecmar/Iomega DittoMax • 5GB HP/Colorado • 6.6GB AIWA Bolt • 7GB Tecmar/Iomega DittoMax • 10GB Tecmar DittoMax • 14GB HP/Colorado Tape Backup Drives and Media 157 The drive manufacturer is the principal supplier of media for some of these drives, whereas others are also supported with third-party media. Consult the drive manufacturers’ Web sites for details. For more information about older QIC and QIC-Wide tape drives and cartridges, see Upgrading and Repairing PCs, 12th Edition, Chapter 12. Getting Extra Capacity with Verbatim QIC-EX Tape Media Many older model, small-capacity tape backups are still in use on older workstations and small networks. The rapid increase in hard disk capacity is causing many problems in creating tape backups that are as safe as possible. The “1 backup = 1 tape” rule is harder to live by when Travan 3 (3.2MB compressed capacity) or smaller tape drives are used with 4GB or larger hard drives. If you use any of the tape standards shown in Table 5.11, you can use the listed Verbatim QIC-Extra cartridges as replacements. Note that the same QIC-Extra series cartridge can be interchanged between a particular QIC, QIC-Wide, and Travan drive type. This is because QIC-EX tapes are the same width as normal QIC cartridges, but are much longer. Because some tape backup drives can’t handle the extra capacity with their own backup software, some models of QIC-EX cartridges come with replacement backup software that will use the full capacity.
