This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see https://mariadb.com/kb/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

Server version: 10.0.33-MariaDB
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467018 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

– MariaDB-backup package is not found for baseurl = http://yum.mariadb.org/10.0/centos7-amd64 or 5.5

– In order to get MariaDB-backup v10.1 and use on MariaDB-Server v10.0 , respectively on MariaDB-Server v5.5
should clean the repo cache and change MariaDB.repo to pint out 10.1
yum clean all
rm -rf /var/cache/yum
change /etc/yum.repos.d/MariaDB.repo to pint out 10.1
install package MariaDB-backup

checked full mariabackup based on MariaDB-backup v10.1
on MariaDB-Server v10.0 and MariaDB-Server v5.5
with backup taken from quiet server
full backup taken from server v5.5 is restored successfully on
server v5.5 with backup-tool v10.1
server v10.0 with backup-tool v10.1
server v10.1 with backup-tool v10.1
server v10.2 with backup-tool v10.2

full backup taken from server v10.0 is restored successfully on
server v10.0 with backup-tool v10.1
server v10.2 with backup-tool v10.2

full backup taken from server v10.2 is restored successfully on
server v10.2 with backup-tool v10.2
checked also with backup taken from one Node and restored on other Node with server v10.2 with backup-tool v10.2
note : when move from one Node to another Node, the step --prepare should be executed on the New Node
before restoring backuped data

partial backup fails to be done server v5.5
note : the partial backup might be done with --export option and --tables option
but it is not automated by the mariabackup tool and it's needed to copy manually data and
also manually from mysql to perform ALTER TABLE xx.yy import TABLESPACE ; statement

note : it found that Service mysql fail to start after restoring from mariabackup ; the problem appears due to ownerchip mysql:mysql of backuped and restored files and directories is not preserved by the mariabackup toll
the Workaround is to change manually the ownerchipod datadir
chown -R mysql:mysql /var/lib/mysql

permission on restore problem has been reported as MDEV-14976

I suspect a mariadb-5.5 with a configuration defined as will be ignored by mariabackup.

[mariadb-5.5]

innodb....

The server version with configuration in a version mysql configuration group matching mariabackup will be solved by https://github.com/MariaDB/server/pull/554 I suspect.
