Description
Server version: 10.11.7-MariaDB source revision: 87e13722a95af5d9378d990caf48cb6874439347

key_buffer_size=0
|
read_buffer_size=131072
|
max_used_connections=0
|
max_threads=1
|
thread_count=0
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 6236 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went

terribly wrong...

This looks a lot like MDEV-31251 MDEV-30968 which where recently fixed, due out next release.
Using "--aria-log-dir-path=." as a mariabackup option until the release should work around this issue.
Can you please install "yum install MariaDB-backup-debuginfo gdb"
And then run:
gdb --args mariadb-backup (arguments used previously)
When it crashes put the following on the gdb prompt:
set print frame-arguments all
thread apply all bt full
Include the output here (as a text file attachment if too big).
