Marcin,
What I have done in the past is setup a bi-monthly base backup
(pg_start_backup:rsync data:pg_stop_backup) and archive the WAL files between
base backups with the archive_command option in postgresql.conf, saving 2 base
backups and removing anything older than the oldest base backup. If you use
rsync with the --link-dest option you can possibly save much space between the
two base backups if you do not have many deletes in your DB. The --link-dest
option assume you are rsyncing to a filesystem which supports hardlinks. I
also gzip the WAL files when archiving them.
But what if my database has ~200GB and more (I know this is a future :D)?
From my point of view it won't be good idea to copy entire database to backup
array. I would like to here opinions about this case - what do you propose?
Maybe some of you already do something like this?
