Why back up the appliance itself?
Plakar Control Plane holds its own configuration and internal database: inventories, resources, apps, schedules, and policies. None of that is duplicated anywhere else by default, so losing the appliance means losing the record of everything it manages, not just the data it protects.
- Hardware failure: a disk or instance failure can take down the appliance itself, independently of any of the resources it backs up.
- Bad upgrades or misconfiguration: an appliance update or a configuration change gone wrong can leave Control Plane in a broken state that’s faster to restore from a backup than to repair by hand.
- Full appliance replacement: migrating to new hardware or a new cloud instance normally means recreating every inventory, resource, app, and schedule from scratch.
How Plakar protects itself
The PCP integration treats the running appliance as a resource like any other, moving data in both directions:
- Source Connector: connect to the running appliance, capture its configuration files and a dump of its internal database, then encrypt and deduplicate the result into a Kloset Store, independent of the appliance it came from.
