The Backup and Restore feature enables you as an administrator of a Terracotta cluster to take a backup of the cluster and restore it from the backed up data when required.

Terracotta supports two ways of taking a backup:

Restore and Ehcache data migration are manual offline processes.

Migration of TCStore data is currently not supported.

When a passive server starts and discovers it has data, the data is automatically backed up for safety reasons. However, this data is not cluster-wide consistent, and must not be used for restoration. Refer to the topic Passive servers in the section Active and Passive Servers for more information.

Backup and Restore : Taking a snapshot of the cluster data such that it can later be installed back on the same cluster, bringing it back to the initial state.

Data Migration : Taking a snapshot of the cluster data, but installing it on a different cluster, bringing it to the state of the original cluster. Data Migration is also desirable in cases when only Ehcache data is needed, and not the platform data.
