Transcript

0:01This video covers the hub as its software moves on.
0:09The drawing starts as video three left it.
0:11hello runs on dev and on fi-01.
0:15The video shows what a saved copy holds.
0:18A lost piece or the whole hub comes back.
0:24The backup is the backend's own command,
0:27typed on the hub host where the backend runs.
0:30The archive stands in the hub host's backups folder and holds the configuration,
0:35the built bundles, the audit log, the agent records and the keys.
0:41Every file but the manifest is sealed with the master key.
0:45The master key and the operator seed are never in the archive.
0:50The check changes nothing.
0:52Every file is read back and matches its manifest.
0:58The variable erp-url of sandbox is deleted by mistake.
1:03The reply says the variable is deleted.
1:06weikio get variables reads the list back.
1:10The answer says sandbox has no variable in devtest.
1:15One document comes back alone.
1:17The backend opens the archive and writes this document back.
1:21The reply reports a new record, and the chip is back.
1:30It carries the archive's value, updated by system:operator.
1:36The audit log holds the hub's record.
1:39The newest row reads Restored variable in devtest.
1:45A fresh host starts with the master key and operator seed.
1:50The rest ran here off camera.
1:53The block prints the time and the parts restored.
1:57What the hub stored after the backup is gone.
2:00weikio status reads both deployments.
2:03hello runs in devtest and in production again.
2:12A release is the version the hub and agents run.
2:15Both rows read release candidate 6.
2:19The backend's command names an upgrade's steps.
2:22Between release candidate 5 and 6, no upgrade step runs.
2:30The stack carries its own upgrade script.
2:32It runs as one command on the hub host, after a backup.
2:37The panel compares a hub that release candidate 5 wrote against release candidate 6's images.
2:43Nothing was written.
2:51Doctor's row names release candidate 6, the release that wrote this stack.
2:56No agent matches, so no agent is behind.
3:02The Health page lists the hub's parts.
3:05The backend row stands Online with release candidate 6.
3:13The backups folder holds the checked archive.
3:16The lost document came back.
3:18One restore brought the whole hub back.
3:21A new release starts with a backup.
