The remote mode is not supported on Windows systems.

The Postgres Pro server from which the backup was taken and the restored server must be compatible by the block_size and wal_block_size parameters and have the same major release number. Depending on cluster configuration, Postgres Pro itself may apply additional restrictions, such as CPU architecture or libc/icu versions.

pg_probackup3 only supports Postgres Pro and PostgreSQL 14 or higher.

For Postgres Pro and PostgreSQL 14: If a new database is created in the instance between a FULL and DELTA backup, incremental backups will fail until a new FULL backup is taken.

It is not recommended to create backups using different backup data source modes within one backup chain. This feature has not been fully tested and may cause errors during the chain restore.

Backing up CFS files is only supported in the PRO mode; the utility operation is not sufficiently tested in other modes, and data integrity is not guaranteed.

The ability to run pg_probackup3 on parallel threads (using the -j option) is currently implemented only for the following commands: backup, restore, merge, and validate.

The default path for WAL files during backup and restore is set to PGDATA/pg_wal.

The --dry-run option only works for the delete command.

Validation is only available for the whole backup.
