Restore failed 2 files

[haus]

Bingo.

And actually re-reading the sha256 hash thread, I saw this comment by @kenkendk:

Please verify the sha256 hash?

It is supposed to work. The error messages seem to indicate that the files are somehow truncated after being stored. Duplicati basically does a file copy from the temporary folder to the destination, so I would assume that you could replicate a similar problem if you copied a file to the CIFS destination manually?

His assumption that I should be able to replicate the problem with a manual copy to a CIFS destination has not been true for me so far. I’ve use the linux cp command to copy the restored files several times to a SMB/CIFS mount and there have been no errors. I’m also currently testing with this command:

dd if=/dev/urandom of=/mnt/helios-restore/large.txt count=50 bs=1048576

where /mnt/helios-restore is a mount on my Windows machine. It keeps writing files that are exactly 52,428,800 bytes, I’ll go bigger and try the same on the NAS as well.
