- TITLE :Using the Colorado Jumbo 250 Tape Backup with Windows NT
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
- SUMMARY
- =======
-
- This article contains information and issues associated with using the
- Colorado Jumbo 250 Tape Backup System with Windows NT and the Windows
- NT Backup program.
-
- MORE INFORMATION
- ================
-
- The following are known issues using the Colorado Jumbo 250 Tape
- Backup System with Windows NT:
-
- No Tape Exchange Between Windows NT Backup and Colorado's Backup
- ----------------------------------------------------------------
-
- Colorado's Backup software format is not compatible with Windows NT
- Backup's tape format. You will not be able to restore a tape using
- Windows NT Backup's Restore function that was originally backed up
- using Colorado's Backup software. You must reformat your tapes with
- Windows NT Backup for use with Windows NT. Also, you will not be able
- to restore a tape using Colorado's Restore function that was
- originally backed up using Windows NT Backup.
-
- Windows NT Backup utilizes Microsoft Tape Format (MTF) as its native
- format. MTF has several advantages over the QIC-40 and QIC-80 system,
- such as built-in security which will not allow unauthorized access or
- unauthorized restoration of data to other computers, without having
- the correct password and permissions. MTF also provides the ability to
- catalog backed-up data to quickly restore data based on special
- criteria, such as time, date, file size, and set.
-
- For more information on MTF, query on the following words in the
- Microsoft Knowledge Base:
-
- mtf and tape and format
-
- Hardware and Software Data Compression is Not Supported
- -------------------------------------------------------
-
- Windows NT Backup supports only the native capacity of the tape. Thus,
- a Jumbo 250 tape has a maximum capacity of 125 megabytes (MB) when
- used with Windows NT Backup.
-
- NOTE: Data compression can be supported by either software (Colorado's
- Backup software) or hardware (Colorado's TC-15 and TC-15M controllers
- - see the following).
-
- Windows NT Does Not Support the FC-10 or TC-15/TC-15M Controllers
- -----------------------------------------------------------------
-
- Technical Note 36 (page 35) in the Windows NT Hardware Compatibility
- List states that all QIC-40/QIC-80 Floppy Tape Drives are supported
- using the floppy controller. Separate interface controllers for these
- types of drives are not supported by Windows NT.
-
- The Jumbo 250 is a QIC-80 (or Ximat) tape drive that connects to the
- floppy controller in a standard configuration. This configuration
- makes the drive's data transfer rate directly dependent on the speed
- of the computer's floppy controller. Most floppy controllers operate
- at a rate of 2 MB to 5 MB a minute.
-
- NOTE: The Colorado Memory Systems tape controllers have a transfer
- rate ranging from 1 megabit (Mb) per second to 500 kilobits (Kb) per
- second, which is twice the speed of an AT floppy controller. The TC-15
- and TC-15M controllers also have a hardware data compression feature.

- System with Windows NT, contact Colorado Memory Systems Technical
