This section provides information about basic requirements for
performing backup and restore operations using MySQL Cluster Manager.
Requirements for MySQL Cluster backup.
Basic requirements for performing MySQL backups using MySQL Cluster Manager
are minimal. At least one data node in each node group must be
running, and there must be sufficient disk space on the node
file systems. Partial backups are not supported.
Requirements for MySQL Cluster restore.
Restoring a MySQL Cluster using MySQL Cluster Manager is subject to the
following conditions:
A complete restore requires that all data nodes are up and
running, and that all files belonging to a given backup are
available.
A partial restore is possible, but must be specified as
such. This can be accomplished using the
restore cluster client
command with its --skip-nodeid option.
In the event that data nodes have been added to the cluster
since the backup was taken, only those data nodes for which
backup files exist are restored. In such cases data is not
automatically distributed to the new nodes, and, following
the restore, you must redistribute the data manually by
issuing an
ALTER
ONLINE TABLE ... REORGANIZE PARTITION statement in
the mysql client for each
NDB table in the cluster. See
Adding MySQL Cluster Data Nodes Online: Basic procedure, for
more information.
