[Duplicity-talk] ioerror 13 permission denied on file locked : terminate

[Bonvicini, Alessandro]

Hi all, thank you everyone for your valuable work on duplicity , but

duplicity fails on files locked by other application.

This is the  v9 trace

IOError: [Errno 13] Permission denied

I found that the problem is the PDOXUSRS.NET ,cause if I try a little python script

like this:

infile = open("/cygdrive/d/gest/SAMW/PDOXUSRS.NET","rb")

while infile:

      line = infile.readline()

it fails with the same error.

So seems to me that duplicity cannot deal correctly with locked file on windows.

I ask if there is a possibility to workaround this behavior that prevent me from use duplicity on my archive, I need this workaround

Urgently cause duplicity is the only valuable software that makes direct diff archive.

If can help, I tried some weeks a go rdiff-backup and it doesn’t terminate on locked file but raise an exception and skip the file.

I don’t know python prog but perhaps someone can get suggestions from rdiff-backup sources

Thank  a lot in advance
