## MySQL LVM Backup Example Backup-Set ## ## This implements a standard MySQL + LVM Backup. For the most part, ## the snapshot options need no modification. Changing the recovery ## and locking options may be occasionally useful. The plugin is designed ## to fit the majority of configurations without needing to make any ## modifications, however. ## Global Holland Settings [holland:backup] plugin = mysqldump-lvm backups-to-keep = 1 auto-purge-failures = yes purge-policy = after-backup estimated-size-factor = 1.0 ## LVM Backup Specific Settings [mysql-lvm] ## The size of the snapshot itself. By default it is 20% of the size of ## the MySQL LVM mount or the remaining free-space in the Volume Group ## (if there is less than 20% available) up to 15GB. ## ## If snapshot-size is defined, the number represents the size of the ## snapshot in megabytes. #snapshot-size = "" ## The name of the snapshot, the default being the name of the MySQL LVM ## volume + "_snapshot" (ie Storage-MySQL_snapshot) #snapshot-name = "" # no default ## Where to mount the snapshot. By default a randomly generated directory ## under /tmp is used. #snapshot-mountpoint = "" # no default ## Whether or not to run a FLUSH TABLES WITH READ LOCK to grab various ## bits of information (such as the binary log name and position). Disabling ## this requires that binary logging is disabled and InnoDB is being used ## exclusively. Otherwise, it is possible that the backup could contain ## crashed tables. lock-tables = True ## Whether or not to run a FLUSH TABLES before running the full ## FLUSH TABLES WITH READ LOCK. Should make the FLUSH TABLES WITH READ LOCK ## operation a bit faster. extra-flush-tables = True ## MySQL Instance Settings ## ## These control the behavior of the MySQL instance which runs on the LVM ## snapshot that mysqldump runs against. Note that only a sub-set of ## MySQL parameters are supported. [mysqld] ## User to run the MySQL instance as. user = mysql ## The size of the InnoDB buffer pool. Larger values can equate to faster ## backups, though be careful as setting this too large could overcommit ## the memory available on the server and could cause swapping. innodb-buffer-pool-size = 128M ## The size of the key buffer. This will likely only affect backup-times ## when using the --where option for mysqldump. Otherwise, it is unlikely ## to affect backup-times. Be careful as setting this too large could ##overcommit the memory available on the server and could cause swapping. key-buffer-size = 128M ## Useful when mysqld is in a non-standard place and not in the PATH. #mysqld-exe = /usr/libexec/mysqld ## mysqldump Settings ## ## These are identical to the settings provided by the mysqldump ## provider. See the mysqldump.conf example configuration file or consult ## the documentation for a full description of options. [mysqldump] file-per-database = yes ## Probably not all that useful in this specific case since the backup ## is of the MySQL instance running on the LVM snapshot and, thus, locking ## may not matter much. lock-method = lock-tables #databases = "*" #tables = "*" #stop-slave = no #bin-log-position = no ## Compression Settings ## ## Identical in behavior to the compression options provided by most of ## the backup plugins. Consult the mysqldump.conf example configuration ## file, or the documentation for a full explanation. [compression] method = gzip inline = True level = 1 ## MySQL Connection Settings ## ## mysqldump-lvm backups are a special case because Holland has to connect ## to the MySQL instance running on the LVM snapshot using an @localhost ## account. As a result, the only useful options here might be to set ## the password, user, or defaults-file [mysql:client] #defaults-file = /root/.my.cnf #user = "" # no default #password = "" # no default
