Re: [Duplicity-talk] strange error when doing a backup

[Scott Hannahs]

Edgar,

Thanks for the pointer.  I removed all the remote copies for that incremental 
backup, manifest, signature etc.  This is an s3 backend.

I removed all files ending in .part and .lock locally and attempted it again.

The manifest seems to contain a list of changed and new files.  I don’t know if 
it is corrupted or not.   As I said, this same command works on other 
directories.  Can it be that the manifest on the remote storage is corrupted?  
There is a hash in the file which I assume is a check on the Filelist portion 
of the manifest.  If that check fails does duplicity recovery gracefully?  I 
will try removing it from the server backend itself.

The note mentions copying a gpg encrypted file but the local file is in clear 
text so that seems to be decrypting properly.  This seems to be an issue with 
the cache syncing if a corrupted file can bring it down.

Thanks for the suggestion, my script now is forcing a full backup but at least 
not aborting.

-Scott
