Hello Jerome, from this I can try to guess that there is some issue with the target storage. Unfortunately technical issues like this require full logs to investigate. Please send all logs from Help | Support information to support@veeam.com to open a support call, and our support staff will work with you to troubleshoot this. Thanks!
