Duplicity 0.6.22 restore fails with error code 21
Asked by
Daniel Hobi
We are using Duplicity 0.6.22 on Ubuntu 10.04 LTS.
A full backup (571 GB) is procesed by duplicity (using symetrical encryption) to a mounted CIFS share with return code 0.
However, in the kern.log we see, during the time of the full backup, messages such as:
CIFS VFS: No response to cmd 47 mid 20561
CIFS VFS: Write2 ret -11, wrote 0
During the restore of this full backup duplicity fails with error code: 21 (= mismatched_hash)
A manual check of the encrypted duplicity volumes confirms that some (about 12) volumes are corrupt.
Our main question is: Why does duplicity not detect the CIFS problems underneath during the backup?
