•  EDB Postgres Backup and Recovery •  EDB Postgres Failover Manager •  EDB Postgres Postgres Enterprise Management

EDB Postgres Management Suite


•  Simplifies and reduces errors with a system-wide catalog and command line tool that allows online backup and recovery across local and remote PostgreSQL and EDB Postgres Advanced servers.

Backup and Recovery

Backup and Recovery


•  Local and remote online physical backups •  Backup catalog to manage multiple PostgreSQL and

Advanced Server databases

•  Auto-compression and MD5 checksum verification •  Verification guards against corrupt files •  Continuous WAL archiving and point-in-time recovery

(PITR) •  Table space restoration on different paths •  Retention policies

Backup and Recovery Feature Highlights

For a given server, the list of backups taken, their ID, Time and Size

For a given server, the list of backups taken and their checksum verification. Note: No md5 generated for uncompressed backups, hence cannot Verify message.

Backup and Recovery Integration with NetBackup Example


•  Creation of highly available configurations of Postgres

•  Monitoring the health of a Postgres HA configuration

•  Automating the failover process in the event of a failure

•  Used in conjunction with streaming replication

EDB Postgres Failover Manager

Create fault tolerant database clusters to minimize downtime


EDB Postgres Failover Manager Based on Streaming Replication

•  Streaming Replication −  Feature of Postgres −  Gives redundancy


•  Agents −  Run on the master and

standby nodes −  Monitors the health of those

databases −  Communicates with each

other and witness to determine cluster health

−  Notifies user if an issue is detected

−  Initiates failover if needed

•  Witness node −  Confirms assertions of either

master or standbys −  Breaks tie in the event of

conflicting assertions

EDB Postgres Failover Manager Architecture and Components

Example Failover Manager cluster that employs a virtual IP address. You can use a load balancer in place of a virtual IP address if you provide your own fencing script to re-configure the load balancer in the event of a failure.


•  Single management console allows easy visual control

•  Works with both PostgreSQL and EDB Postgres Advanced Server

•  Start/stop, configure, define and manage storage, security and database objects via single graphical console
