As per title really, following current affairs I've disabled SMBv1 on
about everything running Windows. After that, none of my Windows
servers back up any more. I've updated Linux itself, added 'min
protocol = SMB2' into smb.conf, even tried putting '-m SMB2' into the
Xfer options but still not happening.
Any ideas? Does Backuppc use SMBv2 even?
You want to look at the mount options for your CIFS mounts. Where you
set these depends on your OS/version (fstab versus systemd) and whether
you use autofs.
