MariaDB Backup and Restore
- This article is a Work in Progress, and may be unfinished or missing sections.
Overview
Backup
Full Backup (Base Backup)
mkdir -p /opt/db_backup/backup mariabackup --backup -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/backup --user=root --password=`zmlocalconfig -s -m nokey mysql_root_password`
Incremental Backup
1st Incremental backup:
mkdir -p /opt/db_backup/inc1 mariabackup --backup -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/inc1/ --incremental-basedir=/opt/db_backup/backup/ --user=root --password=`zmlocalconfig -s -m nokey mysql_root_password`
2nd Incremental backup:
mkdir -p /opt/db_backup/inc2 mariabackup --backup -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/inc2/ --incremental-basedir=/opt/db_backup/inc1/ --user=root --password=`zmlocalconfig -s -m nokey mysql_root_password`
3rdIncremental backup:
mkdir -p /opt/db_backup/inc3 mariabackup --backup -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/inc3/ --incremental-basedir=/opt/db_backup/inc2/ --user=root --password=`zmlocalconfig -s -m nokey mysql_root_password`
Restore
Prepare Backup for Restore
Prepare Base Backup
mariabackup --prepare --apply-log-only -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/backup
Apply Incremental Backup to Base Backup
mariabackup --prepare --apply-log-only -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/backup --incremental-dir=/opt/db_backup/inc1/ mariabackup --prepare --apply-log-only -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/backup --incremental-dir=/opt/db_backup/inc2/ mariabackup --prepare --apply-log-only -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/backup --incremental-dir=/opt/db_backup/inc3/
Restore Prepared Backup
1) Stop MariaDB service.
mysql.server stop
2) Clear existing datadir (/opt/zimbra/db/data) directory. [ensure that the datadir is empty]
mv /opt/zimbra/db/data /opt/zimbra/db/data.OLD mkdir /opt/zimbra/db/data
3) Restore the prepared backup.
mariabackup --copy-back -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/backup OR mariabackup --copy-back -S /opt/zimbra/data/tmp/mysql/mysql.sock --target-dir=/opt/db_backup/backup --datadir /opt/zimbra/db/data
4) Fix the permissions.
chown -R zimbra:zimbra /opt/zimbra/db/data
5) Start MariaDB service.
mysql.server start
