Re: [Duplicity-talk] Recover backup after using PhotoRec

[edgar . soldin]

try to determine how valuable the data in the backup is for you. from there 
decide if it might be worth money to have experts restore your files. if not do 
you have the time to spare to learn how it is done.

a format not necessarily destroys an existing filesystem completely. it depends 
on the format routine which is different for each filesystem and formatter. 
usually a quick format just writes some structures here and there but leaves 
the rest of the sectors alone.

PhotoRec results often are fragments of the files because (taken from photorec 
website)
"
PhotoRec searches for known file headers. If there is no data fragmentation, 
which is often the case, it can recover the whole file. 
"

so if your drive was full before it is very unlikely that the photorec results 
are proper. you can probably already see it if the volume sizes are not nearly 
even sized.

from here on you can try manual restoration
 http://wiki.gnome.org/Apps/DejaDup/Help/Restore/WorstCase#Restoring_by_Hand
with the very big disadvantage that you do not know the order of your volumes. 
so if a file spanned more than one volume you'll have to find out in which.

good luck .. ede

PS: the big advantage of duplicity is that it encrypts safely, so why not put a 
mirror of backup repository on an ftp, in the cloud etc. next time?
