## POSTGRESQL BACKUP CONFIG ##
##############################
# Optional system user to run backups as. If the user the script is running as doesn't match this
# the script terminates. Leave blank to skip check.
BACKUP_USER=
# Optional hostname to adhere to pg_hba policies. Will default to "localhost" if none specified.
HOSTNAME=
# Optional username to connect to database as. Will default to "postgres" if none specified.
USERNAME=
# This dir will be created if it doesn't exist. This must be writable by the user the script is
# running as.
BACKUP_DIR=/opt/backups/
# List of strings to match against in database name, separated by space or comma, for which we only
# wish to keep a backup of the schema, not the data. Any database names which contain any of these
# values will be considered candidates. (e.g. "system_log" will match "dev_system_log_2010-01")
SCHEMA_ONLY_LIST=""
# Will produce a custom-format backup if set to "yes"
ENABLE_CUSTOM_BACKUPS=yes
# Will produce a gzipped plain-format backup if set to "yes"
ENABLE_PLAIN_BACKUPS=yes
# Will produce gzipped sql file containing the cluster globals, like users and passwords, if set to "yes"
ENABLE_GLOBALS_BACKUPS=yes
#### SETTINGS FOR ROTATED BACKUPS ####
# Which day to take the weekly backup from (1-7 = Monday-Sunday)
DAY_OF_WEEK_TO_KEEP=5
# Number of days to keep daily backups
DAYS_TO_KEEP=7
# How many weeks to keep weekly backups
WEEKS_TO_KEEP=5
