[Samba] Error samba backup 4.10.5

[Trenta sis]

Hi,

IT seems that a bug has been opened, thanks!
one question samba 4.10.6 appears delayed when will be released? Will
include a solution for this https://bugzilla.samba.org/show_bug.cgi?id=14027


As workaround is correct to use samba_backup ols script wirh 4.10, it seems
that works..
Thanks
