• AES encryption of backups at rest
• Symlink support for all files
• Hot standby — keep a warm copy of the cluster ready
• Prometheus metrics endpoint for monitoring
• Web console for inspecting metrics
• Remote management via pgmoneta-cli or pgmoneta-mcp
• Offline detection of unreachable instances
• Transport Layer Security (TLS) v1.2+ for client and server connections
• Daemon mode with systemd integration

For RPM-based distributions (Fedora, RHEL, Rocky Linux, AlmaLinux), pgmoneta is available as a pre-built package from the official PostgreSQL YUM repository (PGDG).

Add the PGDG repository — pick and install the matching RPM from the PGDG repo packages page, for Fedora / RHEL / Rocky Linux / AlmaLinux 10, example to install the RPM:

dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-10-x86_64/pgdg-redhat-repo-latest.noarch.rpm

Then to install pgmoneta:

dnf install -y pgmoneta

pgmoneta does not rely on PostgreSQL binary. But if you need PostgreSQL to try the tool, disable the distribution-supplied PostgreSQL module and install the PostgreSQL version of your choice (example for PostgreSQL 18):

dnf -qy module disable postgresql
dnf install -y postgresql18 postgresql18-server

See the Getting Started guide for first-run configuration once the package is installed.
