The format option of pg_dump enables tar and custom archive file formats in addition to the default plain-text file containing SQL commands. When either the tar or custom format are selected the behaviour of database=all is changed to no longer dump a single file via pg_dumpall. Instead pg_dumpall is called once to export the "global" data (roles & tablespaces) and then pg_dump is called once for each non-template table in the database. To support the GZIP and GZIP_OPTS variables in backupninja and to give the default --rsyncable gzip compression flag a chance at working on a PostgreSQL backup, the custom output is forced to not use compression. Instead compression is done via a pipe to gzip. Hopefully this benefits rsync and rdiff-backup style backups for reduced backup and storage costs that outweigh the restoration ones.

### backupninja PostgreSQL config file ###
|
|
|
|
# vsname = <vserver> (no default)
|
|
# what vserver to operate on, only used if vserver = yes in /etc/backupninja.conf
|
|
# if you do not specify a vsname the host will be operated on
|
|
# Note: if operating on a vserver, $VROOTDIR will be prepended to backupdir.
|
|
|
|
# backupdir = <dir> (default: /var/backups/postgres)
|
|
# where to dump the backups
|
|
|
|
# databases = < all | db1 db2 db3 > (default = all)
|
|
# which databases to backup. should either be the word 'all' or a
|
|
# space separated list of database names.
|
|
# Note: when using 'all', pg_dumpall is used instead of pg_dump, which means
|
|
# that cluster-wide data (such as users and groups) are saved.
|
|
|
|
# compress = < yes | no > (default = yes)
|
|
# if yes, compress the pg_dump/pg_dumpall output.
|
|
|
|
# format = < plain | tar | custom > (default = plain)
|
|
# plain - Output a plain-text SQL script file with the extension .sql.
|
|
# When dumping all databases, a single file is created via pg_dumpall.
|
|
# tar - Output a tar archive suitable for input into pg_restore. More
|
|
# flexible than plain and can be manipulated by standard Unix tools
|
|
# such as tar. Creates a globals.sql file and an archive per database.
|
|
# custom - Output a custom PostgreSQL pg_restore archive. This is the most
|
|
# flexible format allowing selective import and reordering of database
|
|
# objects at the time the database is restored via pg_restore. This
|
|
# option creates a globals.sql file containing the cluster role and
|
|
# other information dumped by pg_dumpall -g and a pg_restore file
|
|
# per selected database. See the pg_dump and pg_restore man pages.
|

### You can also set the following variables in /etc/backupninja.conf:
|
|
# PGSQLDUMP: pg_dump path (default: /usr/bin/pg_dump)
|
|
# PGSQLDUMPALL: pg_dumpall path (default: /usr/bin/pg_dumpall)
|
|
# PGSQLUSER: user running PostgreSQL (default: postgres)
