Occasionally, syncing my iDisk would result in error -8088. Google shows a few forum posts by other people having this problem but so far, no solution has been found.

According to ~/Library/Logs/MirrorAgent.log:

*** Syncing “zr40_iDisk” copyCallback: got error -8088 at stage 3. /SourceCache/FileSync/FileSync-99.9.7/Agent/Engine/syncio.m,765 err -8088 (cpfile) /SourceCache/FileSync/FileSync-99.9.7/Agent/Engine/syncio.m,70 err -8088 (syncjobaddobj) *** Exception -8088 logged for “Documents/symlink” *** -8088 FAIL ADDED —> Documents/symlink *** Done syncing “zr40_iDisk”

Apparently, iDisk doesn’t support syncing symlinks. As the symlinks I created weren’t really necessary, I removed them.
