What is the sense of all this fuzz? It takes me a couple of minutes to copy
my most important folders to another disk and there i can find any file in a
very short time!
If we are talking about a few hundreds of MB, periodically copying them with
a crontab can be good enough. Problems arise with larger backups: efficiency
problems, lack of space, etc. See

Why should i learn commands for backing up or look them up each time i want
to restore a file (which rarely is the case)?!
You need not learn any command if you use GNOME's file manager. Otherwise the
'deja-dup' command (see my previous post below), which is far easier (but
less flexible) than 'duplicity' (Déjà Dup's backend).
Why can't the backup program simply show me the folder structure as it was
copied and let me choose which folder/file to restore?
The files are compressed to save space and time (compressing with GNU ZIP and
writing the compressed file is faster than writing the large uncompressed
file). And they are split in medium size pieces to optimize the transfer (I
believe that too small means too much overhead, whereas too large means a lot
to resend if the piece gets corrupted in the process).
