Comment 5 for bug 929139

For backing up and restoring trivial data, especially user home directories, Deja dup is (indeed) a good alternative. The restore problem which I have/had from NAS to the (external) usb disk is a permission problem, which I noticed too with other rsync programs and the command-line rsync.

I share the usb disk (documents and pictures) with Windows 7 (dual boot Ubuntu and Windows). In case of a hard problem of the Linux OS, I prefer to reinstall Ubuntu and restore from NAS the user home directory.

For an image of the entire linux file-system use a more specific program.
