Backup & PITR

Mon, 01 Jan 0001 00:00:00 +0000

Pigsty uses pgBackRest for PITR backup & restore.

In the case of a hardware failure, a physical replica failover could be the best choice. Whereas for data corruption scenarios (whether machine or human errors), Point-in-Time Recovery (PITR) is often more appropriate.

Backup

Use the following command to perform the backup:

# stanza name = {{ pg_cluster }} by default
pgbackrest --stanza=${stanza} --type=full|diff|incr backup

# you can also use the following command in pigsty (/pg/bin/pg-backup)
pg-backup       # make a backup, incr, or full backup if necessary
pg-backup full  # make a full backup
pg-backup diff  # make a differential backup
pg-backup incr  # make a incremental backup

Use the following command to print backup info:

Overview

You can roll back your cluster to any point in time, avoiding data loss caused by software defects and human errors.

Pigsty’s PostgreSQL clusters come with an automatically configured Point in Time Recovery (PITR) solution, based on the backup component pgBackRest and the optional object storage repository MinIO.

High Availability solutions can address hardware failures, but they are powerless against data deletions/overwrites/deletions caused by software defects and human errors. For such scenarios, Pigsty offers an out-of-the-box Point in Time Recovery (PITR) capability, enabled by default without any additional configuration.
