[orca-list] backing up orca

[michael weaver <weavermicha googlemail com>]

after going into the properties menu on my usb stick i found out 
why deja-dup refused to create backups after one backup and it 
was to do with file permissions.
now if i am going to update orca what is the default folder for 
orca when i choose what to backup?
deja-dup backs up home by default but i don't know if this covers 
the orca settings or if i need to add it to my backup.
i think i need to know before i attempt to upgrade from the 
current version of orca that comes with ubuntu lucid.
