Dumping

Usage

$ etcd-dump dump

This is the easiest way to dump the whole etcd keys. Results will be stored in a json file etcd-dump.json file in the directory where you executed the command.

The default Backup strategy for dumping is dump all keys and conserve the order : keys:["/"], recursive:true, sorted:true The backup strategy can be overwritten in the etcd-backup configuration file. See fixtures/backup-configuration.json

Command line options and default values

-config Mandatory etcd-backup configuration file location, default value: "backup-configuration.json". See Configuration section for more information.
-concurent-request Number of concurent resquest that will be executed during the restore(restore mode only), default value is 10.
-retries Number of retires that will be executed if the requests fail, default value is 5.
-etcd-config Mandatory etcd configuration file location, default value: "etcd-configuration.json". See fixtures folder for an example.
-dump Location of the dump file data will be store in (in case of a dump) or load from (in case of a restore), default value: "etcd-dump.json".

$ etcd-dump -config=myBackupConfig.json -retries=2 -etcd-config=myClusterConfig.json -dump=result.json dump

Configuration

The dump.keys supports differents configurations:

{ "key": "/", "recursive": true }

Recursively dump all the keys inside /.

{ "key": "/myKey" }

Dump only the key /myKey.

Dump File structure

Dumped keys are stored in an array of keys, the key path is the absolute path. By design non-empty directories are not saved in the dump file, and empty directories does not contain the value key:

[{ "key": "/myKey", "value": "value1" },{ "key": "/dir/myKey/object", "value": "test" }, {"key": "/dir/mydir"}]

Restoring

Usage

$ etcd-dump restore

Restore the keys from the etcd-dump.json file.

-config Mandatory etcd-backup configuration file location, default value: "backup-configuration.json". See Configuration section for more information.
-concurent-request Number of concurent resquest that will be executed during the restore(restore mode only), default value is 10.
-retries Number of retires that will be executed if the requests fail, default value is 5.
-etcd-config Mandatory etcd configuration file location, default value: "etcd-configuration.json". See fixtures folder for an example.
-dump Location of the dump file data will be store in (in case of a dump) or load from (in case of a restore), default value: "etcd-dump.json".

$ etcd-dump -config=myBackupConfig.json -retries=2 -etcd-config=myClusterConfig.json -dump=dataset.json -concurent-request=100 restore
