DESTINATION_URL SERVER_NAME
Description
The barman-cloud-backup script is used to create a local backup of a Postgres server and transfer it to a
supported cloud provider, bypassing the Barman server. It can also be utilized as a hook script for
copying Barman backups from the Barman server to one of the supported clouds (post_backup_retry_script).
This script requires read access to PGDATA and tablespaces, typically run as the postgres user. When used
on a Barman server, it requires read access to the directory where Barman backups are stored. If
--snapshot- arguments are used and snapshots are supported by the selected cloud provider, the backup
will be performed using snapshots of the specified disks (--snapshot-disk). The backup label and metadata
will also be uploaded to the cloud.
NOTE:
For GCP, only authentication with GOOGLE_APPLICATION_CREDENTIALS env is supported.
IMPORTANT:
The cloud upload may fail if any file larger than the configured --max-archive-size is present in the
data directory or tablespaces. However, Postgres files up to 1GB are always allowed, regardless of the
--max-archive-size setting.
Parameters
SERVER_NAME
Name of the server to be backed up.
DESTINATION_URL
URL of the cloud destination, such as a bucket in AWS S3. For example: s3://bucket/path/to/folder.
-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:
• aws-s3.
• azure-blob-storage.
• google-cloud-storage.
-z / --gzip
gzip-compress the backup while uploading to the cloud (should not be used with python < 3.2).
-j / --bzip2
bzip2-compress the backup while uploading to the cloud (should not be used with python < 3.3).
--snappy
snappy-compress the backup while uploading to the cloud (requires optional python-snappy library).
-h / --host
Host or Unix socket for Postgres connection (default: libpq settings).
-p / --port
Port for Postgres connection (default: libpq settings).
-U / --user
User name for Postgres connection (default: libpq settings).
-d / --dbname
Database name or conninfo string for Postgres connection (default: "postgres").
-n / --name
A name which can be used to reference this backup in commands such as barman-cloud-restore and
barman-cloud-backup-delete.
-J / --jobs
Number of subprocesses to upload data to cloud storage (default: 2).
-S / --max-archive-size
Maximum size of an archive when uploading to cloud storage (default: 100GB).
--immediate-checkpoint
Forces the initial checkpoint to be done as quickly as possible.
--min-chunk-size
Minimum size of an individual chunk when uploading to cloud storage (default: 5MB for aws-s3, 64KB
for azure-blob-storage, not applicable for google-cloud-storage).
--max-bandwidth
The maximum amount of data to be uploaded per second when backing up to object storages (default:
0 - no limit).
--snapshot-instance
Instance where the disks to be backed up as snapshots are attached.
--snapshot-disk
Name of a disk from which snapshots should be taken.
--tags Tags to be added to all uploaded files in cloud storage, and/or to snapshots created, if snapshots
are used.
Extra options for the AWS cloud provider
--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).
-e / --encryption
The encryption algorithm used when storing the uploaded data in S3.
Allowed options:
• AES256.
• aws:kms.
--sse-kms-key-id
The AWS KMS key ID that should be used for encrypting the uploaded data in S3. Can be specified
using the key ID on its own or using the full ARN for the key. Only allowed if -e / --encryption
is set to aws:kms.
--aws-region
The name of the AWS region containing the EC2 VM and storage volumes defined by the
--snapshot-instance and --snapshot-disk arguments.
--aws-await-snapshots-timeout
The length of time in seconds to wait for snapshots to be created in AWS before timing out
(default: 3600 seconds).
--aws-snapshot-lock-mode
The lock mode for the snapshot. This is only valid if --snapshot-instance and --snapshot-disk are
set.
Allowed options:
• compliance.
• governance.
--aws-snapshot-lock-duration
The lock duration is the period of time (in days) for which the snapshot is to remain locked,
ranging from 1 to 36,500. Set either the lock duration or the expiration date (not both).
--aws-snapshot-lock-cool-off-period
The cooling-off period is an optional period of time (in hours) that you can specify when you lock
a snapshot in compliance mode, ranging from 1 to 72.
--aws-snapshot-lock-expiration-date
The lock duration is determined by an expiration date in the future. It must be at least 1 day
after the snapshot creation date and time, using the format YYYY-MM-DDTHH:MM:SS.sssZ. Set either
the lock duration or the expiration date (not both).
Extra options for the Azure cloud provider
--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:
• azure-cli.
• managed-identity.
• default.
--encryption-scope
The name of an encryption scope defined in the Azure Blob Storage service which is to be used to
encrypt the data in Azure.
--azure-subscription-id
The ID of the Azure subscription which owns the instance and storage volumes defined by the
--snapshot-instance and --snapshot-disk arguments.
--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
--gcp-project
GCP project under which disk snapshots should be stored.
--snapshot-gcp-project (deprecated)
GCP project under which disk snapshots should be stored - replaced by --gcp-project.
--kms-key-name
The name of the GCP KMS key which should be used for encrypting the uploaded data in GCS.
--gcp-zone
Zone of the disks from which snapshots should be taken.
--snapshot-zone (deprecated)
Zone of the disks from which snapshots should be taken - replaced by --gcp-zone.
