I recently booted up a new installation of Thunderbird on a new laptop running Fedora Linux after my old Laptop running Ubuntu died. Fortunately, I had been regularly backing up the old machine with Deja Dup. I restored all my files from a recent backup. All my files seem to have been successfully recovered except that many locally-stored Thunderbird messages are missing, and some local folder names have been corrupted. Since I see problems only with Thunderbird, I suspect the problem lies there rather than with Deja Dup. Has anyone else had problems with restoring Thunderbird from backups? Is there something I might try to recover the missing messages and corrupted folders? Should I be using a different backup in the future?
