Postgres Backup Scripts

https://wiki.postgresql.org/wiki/Automated_Backup_on_Linux

Here are some scripts which will backup all databases in a cluster individually, optionally only backing up the schema for a set list. The reason one might wish to use this over pg_dumpall is that you may only wish to restore individual databases from a backup, whereas pg_dumpall dumps a plain SQL copy into a single file. This also provides the option of specifying which databases you only want the schema of. The idea is to run these in a nightly cron job.

pg_backup.config - The main configuration file. This should be the only file which needs user modifications. pg_backup.sh - The normal backup script which will go through each database and save a gzipped and/or a custom format copy of the backup into a date-based directory. pg_backup_rotated.sh - The same as above except it will delete expired backups based on the configuration.

Customization Notes:

We've altered the pg_back_rotated.sh script so that it can be run without a password prompt if executed as the postgres user. So we'd recommend running this as a nightly cron task, with something like.
