Barman 1.3.0 released
Posted on Feb. 3, 2014
2ndQuadrant is proud to announce the release of
version 1.3.0 of Barman, Backup and Recovery Manager for PostgreSQL.
This major release has a new code infrastructure in terms of output,
subprocesses, remote commands, file system, events ('hooks') and
metadata management, making the application more robust.
Barman 1.3.0 introduces a few configuration options for:
- managing hook scripts before and after archiving a WAL file
- network compression of remote backup, and
- recovery operations and immediate checkpoint at backup time
Administrators can now force a rebuild of the "xlog.db" file (WAL
archive) through the "'barman rebuild-xlogdb'" command.
This major version now correctly handles those tablespaces that had been
created inside the "PGDATA" directory, removing content duplication.
Remote recovery code has been improved in order to behave exactly like
local recovery does, including preparation of the directories layout
("PGDATA" and tablespaces).
Minor bugs have also been fixed.
Many thanks for funding towards the development of this release go to
Ecometer (www.ecometer.it), Agile Business
Group (www.agilebg.com) and a French company
(that prefers to remain anonymous).
For a complete list of changes, see the "Release Notes" section below.
- Refactored "BackupInfo" class for backup metadata to use the new
"FieldListFile" class ("infofile" module)
- Refactored output layer to use a dedicated module, in order to
facilitate integration with Nagios ("NagiosOutputWriter" class)
- Refactored subprocess handling in order to isolate
stdin/stderr/stdout channels ("command_wrappers" module)
- Refactored hook scripts management
- Extracted logging configuration and userid enforcement from the
- Support for hook scripts to be executed before and after a WAL file
is archived, through the "'pre_archive_script'" and
"'post_archive_script'" configuration options.
- Implemented immediate checkpoint capability with
"--immediate-checkpoint" command option and "'immediate_checkpoint'"
- Implemented network compression for remote backup and recovery
through the "'network_compression'" configuration option (#19)
- Implemented the "'rebuild-xlogdb'" command (Closes #27 and #28)
- Added deduplication of tablespaces located inside the "PGDATA"
- Refactored remote recovery code to work the same way local recovery
does, by performing remote directory preparation (assuming the
remote user has the right permissions on the remote server)
- "'barman backup'" now tries and create server directories before
attempting to execute a full backup (#14)
- Fixed bug #22: improved documentation for tablespaces relocation
- Fixed bug #31: "'barman cron'" checks directory permissions for
- Fixed bug #32: "xlog.db" read access during cron activities
