Hi,
Got an error with mariabackup during -prepare step on the increment backup.
Distribution:
Ver 15.1 Distrib 10.6.4-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2
I have a full backup without any partitioned tables and the increment backup has table pertionned.
- --------------
- full backup
- --------------
mariabackup --defaults-file=/etc/mysql/my.cnf \
--backup \
--binlog-info \
--target-dir=/var/lib/mysql/backup/full/ \
...

- incremental backup
- -------------------
mariabackup --defaults-file=/etc/mysql/my.cnf \
--backup \
--binlog-info \
--target-dir=/var/lib/mysql/backup/inc1/ \
--incremental-basedir=/var/lib/mysql/backup/full/ \
....
- ----------------------
