Implementation Status

Updated Wed 09-09-2009

Backup / Recovery

1. pitrBackup = 100% complete (We may still find bugs as we engage in further testing)

2. walBackup = 100% complete (We may still find bugs as we engage in further testing)

3. Implement changes based on feedback if needed

4. Unit testing - 100% (Basic Unit tests)

5. Install 'Package” as a directory structure that will contain all future 'tools' /bin, /etc, /tmp, /log, ... Installed on hmidb (after the move to hmidb0 we'll setup the final packages)

6. Setup backup jobs (pending move to hmidb0) Cron entry to run the base file system backup (I suggest once/quarter) Cron entry to archive the WAL segments (monthly) Optional additional base file system backups to alternate locations

The toolset will be run from the warm standby server

Warm Standby

Documented strategy
- Strategy fully dependant on the Backup / Recovery strategy and defined manual steps
- We'll need to address the re-setup of SLONY after a fAIL over as part of the upcoming 'Data Replication' strategy
- I successfully tested the backup of a running warm standby server and then recovering from the warm standby base backup and the subsequent archived WAL files from the master
- walBackup script 100% complete
- walBackup Unit Testing - 100% complete (Basic unit tests)

Web db Plan

Strategy documented - initial pass (100%)

SLONY Plan

SLONY v2 must be used if we want to use PostgreSQL 8.4
SLONY-1 2.03 (release Candidate) recommended due to a few key bugs in 2.01 and 2.02
Next Steps:
- Define SLONY Architecture
- Define Log Shipping process
- Build SLONY scripts/tools
- Implement & Test
