- barman-cloud-restore(1) - Barman-cloud Commands Synopsis 0.0 3.5 barman-cloud-restore [ { -V | --version } ] [ --help ] [ { { -v | --verbose } | { -q | --quiet } } ] [ { -t | --test } ] [ --cloud-provider { aws-s3 | azure-blob-storage | google-cloud-storage } ] [ --endpoint-url ENDPOINT_URL ] [ { -P | --aws-profile } AWS_PROFILE ] [ --profile AWS_PROFILE ] [ --read-timeout READ_TIMEOUT ] [ { --azure-credential | --credential } { azure-cli | managed-identity | default } ] [ --snapshot-recovery-instance SNAPSHOT_RECOVERY_INSTANCE ] [ --snapshot-recovery-zone GCP_ZONE ] [ --aws-region AWS_REGION ] [ --gcp-zone GCP_ZONE ] [ --azure-resource-group AZURE_RESOURCE_GROUP ] [ --tablespace NAME:LOCATION [ --tablespace NAME:LOCATION ... ] ] [ --target-lsn LSN ] [ --target-time TIMESTAMP ] [ --target-tli TLI ] SOURCE_URL SERVER_NAME BACKUP_ID RECOVERY_DESTINATION Description Use this script to restore a backup directly from cloud storage that was created with the barman-cloud-backup command. Additionally, this script can prepare for recovery from a snapshot backup by verifying that attached disks were cloned from the correct snapshots and by downloading the backup label from object storage. This command does not automatically prepare Postgres for recovery. You must manually manage any %PITR options, custom restore_command values, signal files, or required WAL files to ensure Postgres starts, either manually or using external tools. NOTE: 0.0 3.5 For GCP, only authentication with GOOGLE_APPLICATION_CREDENTIALS env is supported. Parameters 0.0 SERVER_NAME Name of the server that holds the backup to be restored. SOURCE_URL URL of the cloud source, such as a bucket in AWS S3. For example: s3://bucket/path/to/folder. BACKUP_ID The ID of the backup to be restored. You can use a shortcut instead of the backup ID. Besides that, you can use auto to have Barman automatically find the most suitable backup for the restore operation. RECOVERY_DESTINATION The path to a directory for recovery. -V / --version Show version and exit. --help show this help message and exit. -v / --verbose Increase output verbosity (e.g., -vv is more than -v). -q / --quiet Decrease output verbosity (e.g., -qq is less than -q). -t / --test Test cloud connectivity and exit. --cloud-provider The cloud provider to use as a storage backend. Allowed options are: 7.0 (bu 2 aws-s3. (bu 2 azure-blob-storage. (bu 2 google-cloud-storage. --snapshot-recovery-instance Instance where the disks recovered from the snapshots are attached. --tablespace Tablespace relocation rule. --target-lsn The recovery target lsn, e.g., 3/64000000. --target-time The recovery target timestamp with or without timezone, in the format %Y-%m-%d %H:%M:%S. --target-tli The recovery target timeline. Extra options for the AWS cloud provider 0.0 --endpoint-url Override default S3 endpoint URL with the given one. -P / --aws-profile Profile name (e.g. INI section in AWS credentials file). --profile (deprecated) Profile name (e.g. INI section in AWS credentials file)
- replaced by --aws-profile. --read-timeout The time in seconds until a timeout is raised when waiting to read from a connection (defaults to 60 seconds). --aws-region The name of the AWS region containing the EC2 VM and storage volumes defined by the --snapshot-instance and --snapshot-disk arguments. Extra options for the Azure cloud provider 0.0 --azure-credential / --credential Optionally specify the type of credential to use when authenticating with Azure. If omitted then Azure Blob Storage credentials will be obtained from the environment and the default Azure authentication flow will be used for authenticating with all other Azure services. If no credentials can be found in the environment then the default Azure authentication flow will also be used for Azure Blob Storage. Allowed options are: 7.0 (bu 2 azure-cli. (bu 2 managed-identity. (bu 2 default. --azure-resource-group The name of the Azure resource group to which the compute instance and disks defined by the --snapshot-instance and --snapshot-disk arguments belong. Extra options for GCP cloud provider 0.0 --gcp-zone Zone of the disks from which snapshots should be taken. --snapshot-recovery-zone (deprecated) Zone containing the instance and disks for the snapshot recovery - replaced by --gcp-zone

- biosig2gdf(1)
- converts different biomedical signal file formats into a simplified version of GDF, and can stream the result to stdout. This is useful for reading the data by an unnamed pipe into different programming environment, while a simplified parser can be used to decode the data. The conversion performs a conversion to GDFv3 format, where all channels have the same data type and the same sampling rate
