Hi Andreas,

do I understand right here:
Instead of using dcfldd or simply dd to copy one disk to
another for backup reasons it is much better/faster to use gparted
to simply copy all partitions from sda to sdb using sda1=>sdb1,
sda2=>sdb2,... and so forth?
Is there something like a "batch job" or scripting interface
for gparted so that I can give gparted the complete copy job
once, go to sleep and next moring the copy is done?
Is gparted able to shut down the system after finishing its
work or to end itsself so a little script can detect the
job is done and halt the system then?

Best regards,
mcc
