Titolo: Clonezilla

...insomma mi pare di capire che Clonezilla sia comodo solo se disco 
sorgente (a) e disco destinazione (b) hanno lo stesso numero di settori 
(una lotteria), perché se
 
a > b  si blocca in partenza
 
a < b si blocca al momento di fare il restore
 
 
Ditemi che sbaglio, per favore :-(

Ma allora sei proprio stupido [ad usare un tale aforismo].
 
Quale sarebbe, allora, la domanda? O la supplica? O la polemica?
 
Mesi fa ti hanno risposto, sopportandoti (te e la tua pigrizia).
Adesso continui a frignare... ...ma su cosa?
Se non riesci a leggere/comprendere, lascia perdere.
 
Addio.

[scusate l'errore nel followup]

 Infatti se non voglio o non so rispondere
mi astengo e stop.
 
Scusami se ho pastato 50 caratteri.
E scusami se forse hai dovuto leggere tutto quel testo
prima di capire di che cosa si trattava.
 
Se non te ne frega di aiutare nello specifico, evita
[anche tu] di andare OT e stop.

no: niente errore: mi si era temporaneamente
incazzato il nr.

 a < b si blocca al momento di fare il restore
 
in effetti clonezilla non si comporta bene con destinazione piu' 
piccola della sorgente. In modalita' avanzata c'e' la possibilita' di 
escludere il controllo della dimensione, se ben ricordo. ma non ho mai 
provato, quindi non saprei dirti se ci sono particolari limiti (oltre, 
ma e' ovvio, che i dati ci devono stare sulla destinazione)

Fatti vedere da un bravo psichiatra.
 

 disco a disco senza problemi.
 
Mi rendo conto.
 
In effetti le mie intenzioni d'uso sono diverse: punterei a fare un 
clone "disk to disk" del mio hard disk, a scopo backup.
 

 "disk to disk" del mio hard disk, a scopo backup.
 
nel dubbio, procurati un disco almeno leggermente piu' grosso, cosi' 
non avrai problemi


In effetti l'ho già fatto, ma si presenta il problema b > a
 
Forse sbaglio qualcosa nel restore?

 Forse sbaglio qualcosa nel restore?
 
nel restore usa la modalita' "esperto" e metti quel flag per ignorare 
il controllo delle dimensioni


Sì grazie, ha funzionato:
 
- ho ridimensionato le partizioni del disco fisso nel PC che è 4 settori 
più grande di quello di backup USB
 
- ho fatto un backup "device to device"
 
- ho fatto un restore "device to device" usando il flag che citavi.
 
Di seguito il log.... Certo non si può dire che clonezilla sia uno 
strumento user-friendly ;-)

 user-friendly ;-)
 
decisamente. Come tutti gli strumenti molto potenti.
Dovresti vedere la clonazione di intere aule informatizzate con la 
versione server.

Un passo ulteriore:
 
Clonezilla ogni volta se ne esce con questo output apparentemente molto 
utile, ma che in realtà non è di facile implementazione:
 
 
PS. Next time you can run this command directly:
/usr/sbin/ocs-onthefly -g auto -e1 auto -e2 -j2 -r -icds -k1  -f sda -t sdb
This command is also saved as this file name for later use if necessary: 
/tmp/ocs-onthefly-2017-07-01-17-30
 
Qualcuno sa come si usa questa modalità batch? capisco poco quel che 
indicano sul sito... pare ci sia un vero e proprio linguaggio Clonezilla...
