With Linux and ZFS, QuTS hero supports advanced data reduction technologies for further driving down costs and increasing reliablility of SSD (all-flash) storage. QuTS hero is the operating system for high-end and enterprise QNAP NAS models. WIth Linux and ext4, QTS enables reliable storage for everyone with versatile value-added features and apps, such as snapshots, Plex media servers, and easy access of your personal cloud. In practice that will only be an issue for clusters with EXTREMELY high write loads, or if you do something like a VACUUM FULL on the master while the slave is being backed up.QTS is the operating system for entry- and mid-level QNAP NAS. The idea for the script was to program a kind of SecureRestore for Linux VMs. This week, we'll turn our attention to the Veeam Data Integration API. As the proverb says, 'A script a week keeps the doctor away'. You also need to ensure that backups complete in a reasonable timeframe so the WAL segments you need to catch up to the master are still available. vbr-securerestore-lnx.ps1 - Secure Restore for Linux VM. The major downsides are that it requires a slave server, and you must make sure that Postgres is stopped on the slave before you grab the PGDATA directory, and is not started again until you're done grabbing the files. This is by far my favorite option for backing up a Postgres cluster - If you dedicate a specific slave server to be the "backups slave" you can perform backups of your cluster with zero impact on production applications using your database. When it's time to back up your cluster, shut the slave down and back up its PGDATA directory as you would for a regular filesystem backup, then restart the slave and let it catch up with the master again. With this method you will need to create a slave server, either log-shipping or hot standby, as described in the Postgres docs. You must ensure that the base backup completes prior to grabbing the files with your regular filesystem backup process, otherwise you might wind up getting an unusable backup. ![]() The result of this backup should be a copy of the PGDATA directory, plus a few WAL segments, stored in a separate location on the server that your normal filesystem-level backup processes can pick up. If you can't shut down the server then contrary to what the manual says here, you can get a usable backup without shutting down the server - Simply to take a "base backup" as you would for setting up a WAL/PITR Slave. Normally this is done by shutting down the server and grabbing the PGDATA directory. The Postgres manual describes two other options which can be automated on Windows with a little scripting. Nearora already described using pg_dumpall which may be viable for you. Postgres is very flexible - there is more than one way to grab a good, usable backup (and many of the best don't require you to use pgAgent - you can script them with regular OS tools). I'd love to hear your reasons considering that PostgreSQL has a way of doing it without external tools and has a well written document on the topic. I am not sure why you are using pgAdmin for automated backups of PostgreSQL. If you chose to authenticate using a password, you can specify that as an environment variable that pg_dumpall will read or specify a file containing the password using a different environment variable. The script can be called via a job setup in Task Scheduler or via a backup scheduler like Bacula. You'll need to modify the pg_hba.conf file to enforce either of these behaviour and the restriction to login from only localhost.Ĭreate a script to use pg_dumpall to backup the database. ![]() ![]() Alternatively, you can also make it a PostgreSQL superuser and enforce login restrictions as mentioned below.Īllow it to login from localhost only by using a password (mechanism 'md5'), or if you are game setup a user on your MS Windows machine and use mechanism 'ident'. Give the user a password and read access to everything. You can use the createuser command from your PostgreSQL install. After you add the S3 compatible object storage repositories with SOSAPI functionality to the backup infrastructure, it will show up as the S3-integrated type in working area. This is what I did a few weeks ago to setup backup of hot backups of PostgreSQL instances hosted on a Windows host:Ĭreate a user specifically for backups, let's call it 'backups'. Veeam Backup & Replication will automatically enable SOSAPI functionality supported by the vendor and provide corresponding capabilities to customers. PostgreSQL provides you all the tools necessary to back it up in it's base install.
