Efficiently Backing up Terabytes of Data with pgBackRest

pgBackRest is open source software developed to perform efficient backup on PostgreSQL databases that measure in tens of terabytes and greater. It supports per file checksums, compression, partial/failed backup resume, high-performance parallel transfer, asynchronous archiving, tablespaces, expiration, full/differential/incremental, local/remote operation via SSH, hard-linking, restore, and more. pgBackRest is written in Perl and does not depend on rsync or tar but instead performs its own deltas which gives it maximum flexibility. This talk by the author will introduce the features, give sample configurations, and discuss design philosophy.
