OS X 10.4.9 and backup to disk image failure
Before updating to 10.4.9, I had made backup User Files from my iMac to a sparseimage on my MacBook over local network. No problems with initial backup or smart updates.
Then I updated both machines to 10.4.9. Subsequently, I made a smart backup of my user files without any apparent problem reported by SD. However, when I tried to mount the sparseimage on the MabBook, I got the following error message: "Disk image you are opening may be damaged..." According to Apple Knowledge Base article (http://docs.info.apple.com/article.html?artnum=305111), OS X 10.4.9 is more robust in its ability to detect damaged or corrupted disk images." I followed the suggested work-around of the article. First I duplicated the sparseimage with Disk Utility. Then I attempted to perform a disk repair of thedisk image with Disk Utility. The repair was unsuccessful and I got the following error message in Disk Utility: "Verify and Repair disk "iMac Backup" Checking HFS Plus volume Checking Extents Overflow file Checking catalog file Invalid sibling link Volume check failed. Error: The underlying task reported failure on exit. 1 HFS voume checked The volume could not be repaired because of an error. So the question is: what next? Do I just make a fresh networkup backup to a new disk image or is this a OS X 10.4.9 problem that interferes with the function of SuperDuper? |
