OmniPITR is a set of scripts to ease setting up WAL replication, and making hot backups from both Master and Slave systems.
This set of scripts has been written to make the operation seamless, secure and as light on resources-usage as possible.
To make it portable, it was written in Perl, but with assumption that it should work on any Perl installation - i.e. no dependencies on non-base Perl modules.
/* Simply fetch the directory https://github.com/omniti-labs/omnipitr, and you're done. More details are in doc/install.pod. */
There is a set of scripts in bin/ directory. All named omnipitr-* are scripts meant for general usage (others are not really useful unless you'll encounter some problems).
For every one of them you will have documentation in doc/SCRIPT_NAME.pod - for example documentation for omnipitr-archive script is in doc/omnipitr-archive.pod.
Quick list of programs:
This should be used on master server, as archive_command command, setup in postgresql.conf.
This should be used on slave server/servers, as restore_command command in recovery.conf file.
Used to make hot backup on master DB server.
Used to make hot backup on slave DB server.
General script for Nagios/Cacti type of systems - monitoring, graphing. Provides a way to check for replication lag, last backup timestamp, and other metrics.
Removes obsolete wal segments from wal archive, when using streaming replication
Send copy of PGDATA to remote locations - even multiple at the same time.
In most of the cases you can simply call the program you want to use with --help option to get brief overview of command line options.
Currently there is simply mailing list that you can subscribe, and post your questions/problems to.
