Hi,
Thanks for your response.
Searching on the forum I found and tried this :
Tutorial: Backup from Windows with putty / plink to a sftp server
For example : @restic_0.13.0_windows_amd64.exe -o sftp.command=“‘D:\Divers\plink.exe’ -s -l user -P 22 -pw Password sftp.xxxx.com sftp” -r sftp:User@sftp.xxxx.com:/files/Testl backup -v -v -v aaaa bbbb --ignore-inode
It works !!! until I get better.
If it could interest someone…
Have a nice day.
