Barman 1.4.0 发布，此版本最主要的功能是文件级别增量备份功能，每次完整备份数据重复数据删除率很容易就能达到 50-70%，显著降低了备份时间和磁盘空间。 PostgreSQL 9.4 可以集成 Barman 的 "pg_stat_archiver" 视图。此版本还改进了 WAL 文件管理，优化 WAL 静态统计数据的计算。相关的单元测试使得代码更健壮，同时还修复了一些 bug。 相关链接 Website: http://www.pgbarman.org/ Download: http://sourceforge.net/projects/pgbarman/files/ Documentation: http://www.pgbarman.org/documentation/ Man page, section 1: http://docs.pgbarman.org/barman.1.html Man page, section 5: http://docs.pgbarman.org/barman.5.html Support: http://www.pgbarman.org/support/ pgespresso extension: https://github.com/2ndquadrant-it/pgespresso 发行说明： Incremental base backup implementation through the "reuse_backup" global/server option. Possible values are "off" (disabled, default), "copy" (preventing unmodified files from being transferred) and "link" (allowing for deduplication through hard links). Store and show deduplication effects when using "reuse_backup=link". Added transparent support of pg_stat_archiver (PostgreSQL 9.4) in "check", "show-server" and "status" commands. Improved administration by invoking WAL maintenance at the end of a successful backup. Changed the way unused WAL files are trashed, by differentiating between concurrent and exclusive backup cases. Improved performance of WAL statistics calculation. Treat a missing pg_ident.conf as a WARNING rather than an error. Refactored output layer by removing remaining "yield" calls. Check that rsync is in the system path. Include history files in WAL management. Improved robustness through more unit tests. Fixed bug #55: Ignore fsync EINVAL errors on directories. Fixed bug #58: retention policies delete. 下载： Release Notes: https://sourceforge.net/projects/pgbarman/files/1.4.0/ Sources: http://sourceforge.net/projects/pgbarman/files/1.4.0/barman-1.4.0.tar.gz/download RPMs for RHEL/CentOS 5: http://sourceforge.net/projects/pgbarman/files/1.4.0/barman-1.4.0-1.rhel5.noarch.rpm/download (dependencies: https://sourceforge.net/projects/pgbarman/files/rhel5-deps/) RPMs for RHEL/CentOS 6: http://sourceforge.net/projects/pgbarman/files/1.4.0/barman-1.4.0-1.rhel6.noarch.rpm/download (dependencies: https://sourceforge.net/projects/pgbarman/files/rhel6-deps/) PyPI: http://pypi.python.org/pypi/barman/1.4.0 pgespresso on PostgreSQL Extension framework (PGXN): http://pgxn.org/dist/pgespresso/ pgespresso RPM/Debian packages: https://sourceforge.net/projects/pgbarman/files/pgespresso/ Online documentation: http://www.pgbarman.org/documentation PDF documentation: http://sourceforge.net/projects/pgbarman/files/1.4.0/barman-tutorial.en.pdf/download Barman (备份和恢复管理器) for PostgreSQL 是 PostgreSQL 数据库服务器的灾难恢复工具，允许远程备份多个服务器，帮助 DBA 在数据恢复阶段的关键工作。 Barman 1.4.0 发布，PostgreSQL 备份和恢复管理器下载地址
