[Duplicity-talk] Problem with "wb" mode on a FAT32 partition

[Marcin Zajączkowski]

Hi,


I tried to use Duplicity to backup my profiles, but I have problem
probably related with a type of partition (FAT32). Duplicity is unable
to create any file (IOError: invalid mode: wb).

Simple backup command on a local file system with a verbosity set to 9.


(...)
Getting delta of (('profiles', 'default', 'vcard')
psi/profiles/default/vcard dir) and None
Generating delta - new file: profiles/default/vcard
Selecting psi/psirc
Comparing ('psirc',) and None
Getting delta of (('psirc',) psi/psirc reg) and None

duplicity-0.4.2
librsync-0.9.7

Is it possible to write backup on a FAT32 partition?
