Hi! Sorry to bother you about this but I haven't found the answers in the doc. ** mariadb-dump Could you tell me what is the difference of calling mariadb-dump on innodb tables using --skip-lock-tables --single-transaction?
From what I read these seem to be time / performace optimizations for doing innodb tables dumps but if we omit them, we would get the same data dumped, even it takes longer.
Could you confirm this? ** mariabackup We have a setup that stores the binary logs under /var/log/mysql (set up with the log_bin configuration option) and the databases themselves under /var/lib/mysql Suppose I call mariabackup to make a backup of the database as follows (some options obmitted): mariabackup --backup --target-dir=my_backup_dir Could you tell me if calling mariabackup --prepare --target-dir=my_backup_dir needs access to the binary logs stored under /var/log/mysql or if mariabackup made a copy of all that it needs in my_backup_dir? ** mariabackup and incremental backups This is basically the same question as the above. If i'm making incremental backups as follows (some options obmitted): mariabackup --backup \ --target-dir=my_backup_dir/inc1 --incremental-basedir=full_backup_dir When I do the prepare for the incremental backups, does mariabackup need access to the /var/log/mysql bin logs or do the full + each incremental backup dirs has all the info needed to do the prepare? mariabackup --prepare \ --target-dir=my_backup_dir/inc1 --incremental-basedir=full_backup_dir Many thanks in advance! --josé
