Mac OS 10.2 (Jaguar) Support and Retrospect




A free update to Retrospect 5.0 is now available.








Retrospect 5.0.236 incorporates support for Mac OS X 10.2 and provides fixes for unexpected behavior seen in Mac OS X and Mac OS 9. Dantz recommends that all customers with Retrospect 5.0 update to this latest version. Retrospect interacts intimately with many of an operating system's components. As Apple continues to improve Mac OS X, some of these components may change, affecting Retrospect’s ability to interact with them. Dantz remains committed to providing the best, most reliable backup software for Macintosh, and we will continue to work closely with Apple to ensure compatibility with Mac OS X as it evolves.




Customers running Mac OS X 10.2.x (or thinking of upgrading) should be aware of the following partial list of known issues affecting Retrospect:




1. An updated Retrospect client that functions properly under Jaguar is available from the Dantz website. This new client allows computers running Jaguar to be backed up by Macintosh computers running Retrospect 5.0 under Mac OS 9 or 10.1.x, and by Windows computers running Retrospect 6.0. The Retrospect 5.0.540 client for Mac OS X is available at the URL below.








2. Many SCSI card vendors will need to update their drivers in order for Retrospect to access attached SCSI devices under Jaguar. The most current list of supported SCSI cards can be found at:








3. Tape Drives and Mac OS X 10.2.x. Dantz has seen several cases where tape drives are not visible to Retrospect running in Mac OS X 10.2.x. This is due to a timing issue with tape drives not responding quickly enough during device discovery. Apple has been made aware of this issue. Until this issue is resolved by Apple, turning the tape drive on several seconds before starting the computer should allow Retrospect to see the drive.




4. Error -40 on clients running Mac OS X 10.2.x. Retrospect generates an error: "Can't read file retropds.22, error -40 (file positioning error)" resulting in the "retro22.pds" file not being backed up. This file is necessary for the Retrospect client software to operate correctly. Dantz is working with Apple to solve this problem. In the meantime, the Retrospect client software should be reinstalled manually following a Mac OS X 10.2.x system restore.

The following issues have been resolved with this updated version of Retrospect




OS X v10.2 (Jaguar) Specific




Live Restores: You can perform a live restore without changing the Time Zone setting in the Date & Time system preferences to GMT (Greenwich Mean Time).




Startup authentication: The startup authentication option and passwords function correctly.




Erasing Removable Disks: Retrospect can successfully erase removable disks.




Backup Server Defer Button: The Defer button in the Backup Server alert window functions correctly.




Autolaunching Retrospect: Retrospect launches automatically to execute its scheduled scripts.






General OS X




Internet Backup Sets: Retrospect displays the correct FTP directories for Internet backup set destinations, even when multiple Active Network Ports are selected in the Network pane of System Preferences.




Autolaunching Retrospect: If Retrospect autolaunches when no user is logged in, access to the Apple Menu is prohibited.




AppleScript Support: AppleScripts function correctly when Retrospect autolaunches.




-43 (file not found) Errors: Retrospect is better able to handle files with bad text encoding, resulting in fewer -43 errors.




Duplicating the OS: Retrospect has improved capability to create bootable disks using the Duplicate operation.




Unattended Operations: Unattended operations will run in unattended mode until Run Interactively is selected from the Control menu.




Backup Server Memory Leak: A memory leak that could occur when Retrospect was running Backup Server has been fixed.




File Backup Sets on AFP Volumes: File backup sets saved on mounted AppleShare File Server (AFP) volumes function as expected, even after the backup set has been split. (Retrospect automatically splits a file backup set into a catalog file and a data file once the backup set reaches a certain size).






OS X Clients




Exported Backup Reports: Machine names for OS X clients are correctly listed in exported Backup Reports.




Scanning OS X Client Files: Retrospect running on Mac OS 9 can scan files on OS X client computers much more quickly than before.
