Hi MT!<br>
<br>
And which significant differences I see in zfs properties (sorry for
HTML but without it -- the difference is not so evident):<br>

1. Atime. Maybe this backup software relies on atime some way?
Anyway, atime for root FS is important.<br>
2. Aclmode+aclinherit. These are for ACLs. Non-defaults are used for
shares, for root FS the default is must.<br>
3. Utf8only+normalization+casesensitivity. These are for file names.
Maybe backup assumes that, ex., .lock and .LOCK are different files
(usually on UNIX and Linux tis is true ;) ). BTW Linux (like UNIX or
BSD or evem MacOS) likes case-sensitivity and "insensitive" is for
network shares for windows-like clients.<br>
4. Nbmand. This is some kind of locking, I don't know details. But I
also think that non-default is not a good idea for linux root.<br>
<br>
So, I think that "right column" is not siutable as linux root
filesystem - because of case insensitivity, atime=off and uncommon
acls+nbmand.<br>
<br>
This is my opinion. And if You want - You definitely can fix these
settings one by one and realize what is the unique cause of backup
creash. It seems so.<br>
