#Youtube backuplist how to
In that regard, we will publish a new blog article soon explaining how to prepare the recovery of a PostgreSQL instance using these commands.
With the release of Barman 2.11, which happened a few days ago, important new features have been introduced, including the barman-cloud-wal-restore and the barman-cloud-restore commands, which allow to retrieve the backup and WAL files from an object store such as AWS S3. It supports encryption, parallel upload, compression, and allows to save disk space on your local server and transfer safely the backups to the cloud. With the barman-cloud-backup command Barman introduces an important feature that allows you to execute and directly ship base backups from a local PostgreSQL server to cloud object storage services that are compatible with AWS S3 in just a few simple steps. Great! As we can see, all the files in the DATADIR of the PostgreSQL instance that we backed up, including the configuration files, are listed correctly here. PG_VERSION conf.d pg_commit_ts pg_nf pg_notify pg_snapshots pg_subtrans pg_wal nfīackup_label 2 pg_dynshmem pg_logical pg_replslot pg_stat pg_tblspc pg_xactīase global pg_hba.conf pg_multixact pg_serial pg_stat_tmp pg_twophase We can restore the backup by copying and unzipping the 2 file on our local server as shown below: :~ $ aws s3 -profile barman-cloud cp s3://barman-s3-test/pg12/base/20200713T120856/2 restore-dirĭownload: s3://barman-s3-test/pg12/base/20200713T120856/2 to restore-dir/2 Let’s look at its contents: :~ $ aws s3 -profile barman-cloud ls s3://barman-s3-test/pg12/base/20200713T120856/Īs we can see, there is a compressed and encrypted file containing our backup ( 2) and a file called containing the information related to the backup. The 20200711T092548 directory contains all files related to the backup that we have just executed. Let’s check it, building the destination path with the server name and the base directory: :~ $ aws s3 -profile barman-cloud ls s3://barman-s3-test/pg12/base/Īlternatively, you can use barman-cloud-backup-list, but in this article I would like to focus on the mechanics behind it. Once the backup has been completed successfully, the base directory containing the backup will be in your S3 bucket. e AES256 -j -immediate-checkpoint -J 4 \ Now that we have a clearer idea of the command and its options, we are ready to execute our first cloud backup: :~ $ barman-cloud-backup -P barman-cloud \ Override default S3 endpoint URL with the given one

In this second part, I will show you how the barman-cloud-backup command works.Īs you can guess from the command name itself, the barman-cloud-backup command allows you to execute backups directly from a PostgreSQL server and use an S3 compatible object store in the Cloud as destination. Now, assuming you followed those instructions, you have a properly configured PostgreSQL instance up and running. In the first part of this blog, Jonathan explained how the barman-wal-archive command works.
