This hypertext document contains important information about Retrospect version 5.11 for Windows. Please read this document carefully. The Retrospect family of backup software includes Retrospect Desktop Backup, Retrospect Workgroup Backup, and Retrospect Server Backup. Unless otherwise noted, all items in this document refer to all members of the Retrospect backup family.
The Dantz web site is constantly updated with the most recent support information for Retrospect and related products, including the following:
This document is divided into the following sections:
License Codes: Retrospect requires a license code to function. The first time you start Retrospect, enter the license code.
If you purchased your Retrospect software for electronic download, your license code should be e-mailed to you by your vendor; if you did not receive the code, contact your vendor. Write down or print out your license code for future reference and keep the code in a safe place. Without this license code, you will not be able to use your Retrospect software.
Adding a Backup Device: When you install a new backup device on your computer, you may need to take some extra steps to satisfy Windows' Add New Hardware wizard. If you are installing a CD-R or CD-RW device or a new removable device such as a Zip, Jaz, DVD-RAM, or SuperDisk, follow the instructions included with it to install required device drivers. If you are installing a tape drive, follow the appropriate steps below, according to your operating system. No action is required for Windows NT 4.0.
Windows 2000 Support: Retrospect 5.1 offers full support for Windows 2000 Professional and extensive support for Windows 2000 Server. Windows 2000 Server support includes backup and restore of Active Directory, COM+, and Certificate Server databases. Support for Windows 2000 is fully documented in the Retrospect 5.1 User's Guide Addendum.
Windows Socket 2 Update for Windows 95: Windows 95 clients require the Windows Socket 2 Update, available at no charge from Microsoft. Known as Winsock2, it is required only for Windows 95, and is available free from Microsoft's web site.
Microsoft Windows 95 TCP/IP Fix: A bug in Windows 95 networking software can cause Retrospect to report a networking error. Microsoft has resolved this problem and a free fix is available from Microsoft. Windows 98, Windows NT 4.0, and Windows 2000 do not require an update. We strongly urge you to update your Windows 95 systems.
The hot fix for Windows 95 is installed by the client software Setup program. After installation, choose Run from the Start menu, then type "C:\Program Files\Dantz\Client\VTCPUPD" (or your different installation path) and click OK. Follow the instructions in Microsoft's installer, then restart to complete the fix. Repeat for each Windows 95 computer to be used with Retrospect.
The problem can occur when Retrospect pauses then later resumes a TCP/IP network transfer. For example, it can happen when Retrospect requests media during the nightly backup and you insert a new tape the next morning. The bug can cause Retrospect to report error -519 (network communication failed) when it resumes a paused transfer.
Suspend: If you or a client user uses the "Suspend" function of Windows 95, which powers off a mobile computer without shutting it down, you must restart the client computer before Retrospect can access it. Microsoft has an update to address this problem, but Microsoft does not recommend updating unless you are severely impacted by it. For more information about this problem and the update, visit Microsoft's web page. This problem is resolved in Microsoft Windows 98.
AppleShare 4.2.1: When restoring or duplicating files to an AppleShare file server disk, some copied applications can be assigned incorrect type and creator codes, such as BINA and pdos. This is caused by a bug, which is fixed in AppleShare IP 5.0 and later.
First Class server: To avoid problems with a First Class server, close down the First Class server before backing it up. With a version earlier than 3.5, also run the utility to update the Post Office Map. This avoids errors with backups and ensures the server can be restored.
AccessPC: If you use AccessPC on a Macintosh which you plan to back up using Retrospect client software, rename the °Retrospect Client control panel file by replacing the "°" with a space. When the client Macintosh starts up, the renamed control panel loads before AccessPC, ensuring compatibility.
Apple Ethernet drivers on beige G3 Macs: Apple's beige G3 Ethernet drivers version 2.0, 2.0.1, 2.0.2, and 2.0.3 drivers have a problem that can cause network backup failures and loss of network services when using the built-in Ethernet interface of beige G3 desktop and mini-towers (but not PowerBook G3). Apple fixed the problem with version 2.0.4 of its built-in Ethernet software. If you experience network backup trouble on beige G3 computers you should update your driver. You can learn more about and download the latest driver from Apple.
At Ease for Workgroups: When backing up a server running At Ease for Workgroups, Retrospect may report error -54 (file busy/locked) when copying the following At Ease files: setups.data, setups.idx, Users.data, Users.idx.
AutoDoubler: For best compatibility, use version 2.0.6 or later, which is part of Norton DiskDoubler Pro 1.1.3. If you have questions about AutoDoubler, contact Symantec at 541.465.8440 or 800.441.7234. During the compare pass of a duplicate operation Retrospect reports a data offset error at byte 40 for a number of AutoDoubler-compressed files. This is caused by an AutoDoubler bug in which it does not set the BNDL bit of compressed applications. It is important to understand that the data is not corrupt and that the issue is only cosmetic. Use a program such as Norton Utilities to fix affected applications.
Energy Saver: Apple's Energy Saver control panel can put a non-PCI client Macintosh into "sleep" mode, which may produce error -530 with network backups. Avoid this problem by using the Retrospect Client control panel's "Wait at Shutdown" preference and shutting down the client to put it in the "waiting for backup" mode, or by setting the CPU sleep option to never sleep.
General Controls: Early versions of the General Controls control panel included with System 7.5 sometimes caused Retrospect to report error -15276 or error -15277. To avoid these errors, update your system software to version 7.5.3 or later.
Launcher: To avoid conflicts concerning the bullet character (Option-8) in folder names, client Macintosh computers using the Private Files/Folders/Volumes preference should use aliases in the Launcher Items folder. After a restore, you may need to manually rebuild the Launcher Items folder. Any time you use the Private Files/Folders/Volumes preference, you must ensure only files not desired for backup are restricted by the bullet character. This includes folders enclosing files.
Mac OS Extended Format (HFS+) Time Zone: When the local time zone is changed in the Date & Time control panel, the Mac OS shifts the local creation and modification times of files on HFS+ (extended format) volumes. This affects Retrospect's normal backups when it scans the volumes for files which need to be backed up. Because file date/time stamps are different, Retrospect marks every file for backup. Retrospect is simply performing an incremental backup as it usually would; the only abnormality is that every file appears to have been modified. For more information regarding HFS+ date/time stamps, refer to Dantz Technical Note 405, "Effects of HFS+ on Retrospect when Standard or Daylight Savings Time Changes."
Mac OS Extended Format (HFS+) Daylight Savings Time: Under Mac OS 8.1, changing the Daylight Savings time setting shifts the local dates and times of files on HFS+ volumes. This affects Retrospect as described in the previous topic. Mac OS 8.5 solves this problem because it does not alter file date/time stamps when you change Daylight Savings in the Date & Time control panel. For more information regarding HFS+ date/time stamps, refer to Dantz Technical Note 405.
Microsoft Mail: Microsoft Mail 3.0 and 3.1 data files on an MS Mail workstation often become corrupted. MS Mail 3.1a data files become corrupted when the workstation's mail application is open while Retrospect backs it up. Update to version 3.1a and implement a custom Selector with Retrospect that excludes busy MS Mail data files.
Microsoft Office Manager: A bug in the Microsoft Office Manager (MOM) extension causes the Finder to hang or prevents shutdown when Retrospect is scanning the volume. Update to version 4.2.1c, part of Microsoft's Office update for Power Macintosh.
Now QuickFiler (formerly Now Compress): For best compatibility, use version 5.0.2 or later and set it to compress individual volumes rather than all volumes. If you have questions about Now QuickFiler contact Power On Software.
RAM Doubler: You must use version 2.0.1 with System 7.5.5 or later.
Speed Doubler: You must use version 1.1 or later. Prior versions may result in hangs during restore operations with large volumes.
Some specialized accounting software: To ensure the integrity of backups for the MediMac®, DentalMac®, ChiroMac®, and Great Plains accounting systems, back up as described on page 159 of the Retrospect User's Guide, under "Programs Which Do Not Update File Dates." To restore your accounting data, always use the "Restore an entire disk" option to restore the Snapshot of the accounting Subvolume to a new, empty Subvolume.
Asante 10/100 Ethernet card: A bug in this network card causes the Macintosh to hang with TCP/IP. Asante's version 2.4 or later of the Mac 10/100 driver takes care of the problem with the card. The new driver disk image is posted on Asante's web site.
PowerBook 3400: A PowerBook 3400 TCP/IP Retrospect client may halt network communication during a backup. Retrospect reports an error -519 as the PowerBook's networking stops. (You will find both TCP/IP and AppleTalk networking non-functional until you restart the computer.) Apple has provided a software fix, which you can learn more about and download from Apple. Upgrading to Mac OS 8.1 also fixes the problem.
Mac OS clients don't renew DHCP leases while waiting for shutdown: When a Mac OS TCP/IP Retrospect client has a DHCP-supplied IP address and its lease expires while the client is waiting for shutdown, the Mac does not renew its IP lease and continues using its old IP address. This can lead to a conflict when the DHCP server, thinking the IP address is now available, leases the IP address to a different computer.
There are two possible workarounds: leave DHCP-served Mac OS computers idle in the Finder instead of in the Retrospect client "Wait at Shutdown" mode and uncheck "Load Only When Needed" in the TCP/IP control panel; or, lengthen your DHCP server's lease period. The likelihood of encountering this problem decreases as the length of DHCP leases increases.
Windows NT 4.0 and ATAPI devices: Windows NT 4.0 Service Pack 3 and later greatly improve compatibility with ATAPI storage devices. If you are encountering problems with an ATAPI storage device, contact the computer vendor for a new IDE controller driver.
Removable Storage Management: Windows 2000's Removable Storage management console allows you to manage tape libraries and other storage devices in conjunction with the operating system's built-in backup utility. Because this interferes with Retrospect's access of those same devices, Retrospect automatically disables the Removable Storage service when it scans the SCSI bus for devices.With the service disabled, you cannot use the Removable Storage management console.
DVD-RAM Drives: Retrospect will not recognize a DVD-RAM drive if a DVD-RAM disk was not in the drive before Retrospect scanned for available backup devices. If the DVD-RAM drive is not visible in Retrospect's media request window, check whether Windows Explorer shows a drive letter for a removable disk in My Computer. If the DVD-RAM drive has a letter in Windows Explorer but it is not in the media request window, click Device Status to open the device status window, then click Refresh.
Write DVD! Driver: When this driver from Software Architects is in use, Retrospect cannot eject DVD-RAM disks because the driver intercepts eject requests. Use Windows Explorer to eject media.
DirectCD: Retrospect is not able to access a CD-R or CD-RW device if an Adaptec DirectCD-formatted disc is in the drive. Eject all DirectCD volumes from the CD-R or CD-RW drive before opening Retrospect.
Removable Disks: If you are using a removable disk drive under Windows NT, format your disks as NTFS, unless you need to keep them FAT to share data with others. Erasing FAT volumes for use with Retrospect takes longer than erasing NTFS volumes.
Imation LS-120 SuperDisk: Retrospect will not recognize a SuperDisk drive if a 1.4 M floppy disk was in the drive before Retrospect scanned for available backup devices. If the SuperDisk drive is not visible in Retrospect's media request window, check whether Windows Explorer shows a drive letter for a removable disk in My Computer. If the SuperDisk drive has a letter in Windows Explorer but it is not in the media request window, click Device Status to open the device status window, then click Refresh.
Auto-Ejecting Removable Disks: Windows 95 and 98 may give you a blue screen error message when Retrospect automatically ejects a removable disk. To prevent this, go to Special>Preferences>Media>Handling and turn on the Don't eject removable disks preference.

Retrospect is all the software required to support most tape drives.
NOTE: Regular cleaning of your tape drive is essential for reliable performance. Dirty drive heads are the number one cause of tape drive problems and reported media failures (error -206). Retrospect can remind you to clean your drive at the specified interval of hours of tape drive use. See the Retrospect User's Guide. Refer to your drive's documentation for its manufacturer's cleaning recommendations.
NOTE: If you wish to exchange tapes with people who do not have compression drives, turn off Retrospect's hardware compression option when creating backup sets.
DAT cartridges are available in lengths of 60 to 150 meters and range in capacity from 1.2 GB to 20 GB.
The following table shows the different tape lengths supported by the different DDS formats. It also shows the uncompressed capacity of each tape length when used on a drive of a given format.
| 60m | 90m | 120m | 125m | 150m | |
|---|---|---|---|---|---|
| DDS | 1.2 GB | 1.9 GB | not supported | not supported | not supported |
| DDS-2 | 1.2 GB | 1.9 GB | 4 GB | not supported | not supported |
| DDS-3 | 1.2 GB | 1.9 GB | 4 GB | 12 GB | not supported |
| DDS-4 | 1.2 GB | 1.9 GB | 4 GB | 12 GB | 20 GB |
Tapes created on one drive can typically--but not always--be read by drives of another manufacturer, provided they are of the same format. A few drives use the DataDAT and DVDS formats, neither of which is compatible with the more common DDS format or its successors. Use care when interchanging tapes among drives from different vendors: DAT tapes written in one drive may erroneously show as "erased" when inserted in a DAT drive using a mechanism from a different manufacturer. During unattended backup, Retrospect automatically overwrites tapes that appear as erased.
Though they are derived from the same technology and use the acronym for Digital Audio Tape, DAT drives should be used with only data grade tapes--not audio grade--for reliable storage.
Older data grade DAT tapes may not implement the Media Recognition System, required for use by some DAT drives. Problems with non-MRS data grade tapes (for example, the tapes appear as write-locked) are best solved by using MRS tapes, recognizable by the MRS logo on their packaging. Should you insist on using non-MRS tapes, contact the drive vendor for assistance. (Some drives' MRS requirements can be turned off with a DIP switch.)

When an 8mm drive is turned on, it automatically sets itself to the highest capacity possible for that drive. When a new tape is inserted and erased by Retrospect, it is initialized to the drive's current setting. Once initialized, the tape retains its density/compression setting. If you own only one kind of Exabyte drive and buy new tapes, maximum capacity will be achieved by default. You can format tapes in your choice of density format by inserting a tape in the drive, going to Configure>Devices, selecting the tape, and choosing Format from the devices toolbar. After confirming the format, Retrospect asks you which drive density format to use.

For best results with Travan drives, rewind tapes before you eject them. To remove a tape from a drive, first click the Eject button in the storage devices window or quit Retrospect (which automatically rewinds tapes). Then wait while the drive rewinds the tape. When the access stops, you may remove the tape.
Travan TR-5 and NS20 drives can write only to TR-5 tape cartridges, but they can read QIC-3095 and TR-4 tapes.

Tapes written by one drive can typically be read by another of equal or greater capacity.
A separate formatting step is not required, though the first time Retrospect uses a DC6000 tape, it performs a "long erase," which retensions the tape, erases all previous data, and determines the tape's format and capacity.
Streaming, or sequential mode, DC2000 drives are similar to DC6000 drives in that they are not block-addressable, and some of these do not require time-consuming formatting. For best results with DC2000 sequential mode drives, rewind tapes before you eject them. To remove a tape from a drive, first click the Eject toolbar icon in the storage devices window or quit Retrospect. Then wait while the drive rewinds the tape. When the access stops, you may remove the tape.
Libraries with nine or more tape slots require Retrospect Workgroup Backup or Retrospect Server Backup. Retrospect Desktop Backup supports libraries with up to eight tape slots.
Some libraries have the tape drive at one SCSI address and the loading mechanism at another, whereas others integrate the two into a single SCSI address. Retrospect uses only one drive at a time with loaders having two or more drives. Refer to the Retrospect User's Guide for information on Retrospect's library features.
Choose Eject Magazine from the devices toolbar to clear the tape drive or drives before opening the door or removing the tape magazine.
Some libraries have LCD panels to control actions such as ejecting tapes from drives and moving tapes between slots. Retrospect can encounter problems when you use the LCD controls to manipulate the library while Retrospect is also manipulating the library. Avoid trouble by controlling library functions only from Retrospect, or exit Retrospect before you use the library's manual controls.
Retrospect supports designating a slot in a library exclusively for a cleaning cartridge. With a slot designated for a cleaning cartridge, Retrospect will not move a tape from that slot to the drive when Retrospect scans slots to find a tape. To clean the library's tape drive, use the library's controls to move the cleaning cartridge from its slot to the tape drive. Refer to your library's documentation for its manufacturer's cleaning recommendations. If you put a cleaning cartridge in a library slot, be sure to designate that slot as reserved by selecting the slot in Retrospect's devices window and choosing Cleaning Slot from the toolbar.
