I'm getting persistent errors when trying to backup my home directory to DVD using Toast. At first I thought I was suffering from a lot of bad discs, but then I tried backing up to a disc image on an external hard disk, and I'm seeing the same problems. So it's not a disc burning issue; it seems to be some corruption of the files in my home directory. I keep getting error messages like this one:
The file "Untitled Workspace 3.oww" could not be accessed. (Data fork, -43)
I then click OK and get another error message:
Couldn't complete the last command because a file couldn't be found.
Result Code = -43
I click OK and then Toast aborts the backup. Ick.
All right, so there's some corruption of my hard disk directory somewhere. Fine. I rebuilt the disk with Disk Warrior, repaired disk permissions, and rebooted, then tried another backup with Toast. The same "file could not be accessed" error came up, but this time with a different file.
Okay, no big deal, I can cope with a few files not being accessed. If Toast can't back them up, it can log the error and continue with the rest of the files, right?
Wrong! Do you know what Toast does? It aborts the entire backup! One file error and the whole backup set is ruined. I have to throw away whatever discs I had burned so far in that backup set.
Why does Toast do this? Why can't it just ignore the error and continue? Is this a bug?
I'm using Toast 7.1 on Mac OS X 10.4.7. Format is "Mac Only"; the Compressed and Encrypted options are turned off. Data size is about 36GB spanning 9 DVDs.
