I created a backup on an external hard disc. Then I created another backup and copied all files to another external hard disc. I wanted to check with
diff if everything was copied:
user@user:/media/user$ diff -r backup backup1 Nur in backup1/home/user: file.xls. Nur in backup1/home/user: file.zip.
("nur" is German for "only".)
The diff shows two files that are not existing:
user@user:/media/user$ file backup1/home/user/file.xls. backup1/home/user/file.xls.: cannot open backup1/home/user/file.xls. (No such file or directory) user@user:/media/user$ file backup1/home/user/file.zip. backup1/home/user/file.zip.: cannot open backup1/home/user/file.zip. (No such file or directory)
How does it come that diff shows these two files, and how can I fix the output of diff? The filesystem is LUKS on both external hard drives.
