Extend Ark

Ark includes mechanisms for extending the core functionality to meet your individual backup/restore needs:

Hooks allow you to specify commands to be executed within running pods during a backup. This is useful if you need to run a workload-specific command prior to taking a backup (for example, to flush disk buffers or to freeze a database).
Plugins allow you to develop custom object/block storage back-ends or per-item backup/restore actions that can execute arbitrary logic, including modifying the items being backed up/restored. Plugins can be used by Ark without needing to be compiled into the core Ark binary.
