36a5349b1c Added the --checksum-page option.
This option allows pgBackRest to validate page checksums in data files when checksums are enabled on PostgreSQL >= 9.3. Note that this functionality requires a C library which may not initially be available in OS packages. The option will automatically be enabled when the library is present and checksums are enabled on the cluster.

f818901c0e Added the --repo-sync option to allow directory syncs in the repository to be disabled.
This is for file systems that do not support them, e.g. NTFS

David Steele
817592837c Added a predictable log entry to signal that a command has completed successfully.
For example a backup ends successfully with: INFO: backup command end: completed successfully.

f823a25ac2 Fixed an issue where options that were invalid for the specified command could be provided on the command-line without generating an error.
* The options were ignored and did not cause any change in behavior, but it did lead to some confusion. Invalid options will now generate an error.
* Removed erroneous --no-config option in help test module.
* Changed the --no-fork test option to --fork with negation to match all other boolean parameters.

d18cd7ad0f Fixed an issue that prevented errors from being output to the console before the logging system was initialized.
That is, while parsing options. Error codes were still being returned accurately so this would not have made a process look like it succeeded when it did not.

2e01e6b9e1 Improved consistency and flexibility of the protocol layer by using JSON for all messages. 2016-12-03 17:34:51 -05:00
David Steele
005fc08795 Added the --repo-link option.
Allow internal symlinks to be suppressed when the repository is located on a filesystem that does not support symlinks. This does not affect any pgBackRest functionality, but the convenience link latest will not be created and neither will internal tablespace symlinks, which will affect the ability to bring up clusters in-place manually using filesystem snapshots.
2016-12-03 10:23:26 -05:00
David Steele
6ae4d7de81 Fixed a bug where internal symlinks were not being created for tablespaces in the repository.
This issue was only apparent when trying to bring up clusters in-place with filesystem snapshots and did not affect normal backup and restore.

David Steele
09df07efb7 For simplicity, the pg_control file is now copied with the rest of the files instead of by itself of at the end of the process.
The backup command does not require this behavior and the restore copies to a temporary file which is renamed at the end of the restore.

dbb9d80dab Fixed an issue where asynchronous archiving was transferring one file per execution instead of transferring files in batches.
This regression was introduced in v1.09 and affected efficiency only, all WAL segments were correctly archived in asynchronous mode.

5dc801d59d Fixed an issue where the async archiver would not be started if archive-push did not have enough space to queue a new WAL segment.
This meant that the queue would never be cleared without manual intervention (such as calling archive-push directly). PostgreSQL now receives errors when there is not enough space to store new WAL segments but the async process will still be started so that space is eventually freed.

Reported by Jens Wilke.

2a18674111 Added the log-level-stderr option.
Controls whether console log messages are sent to stderr or stdout. By default this is set to warn which represents a change in behavior from previous versions, even though it may be more intuitive. Setting log-level-stderr=off will preserve the old behavior.

Suggested by Sascha Biberhofer.

d2add293c7 Archive retention improvements:
* Fixed an issue where retention-archive was not automatically being set when retention-archive-type=diff, resulting in a less aggressive than intended expiration of archive.
* Additional warnings when archive retention settings may not have the intended effect or would allow indefinite retention.
* Closed #235: "Retention policy question" by adding documentation for archive retention.

5ada189a92 Backup from a standby cluster.
A connection to the primary cluster is still required to start/stop the backup and copy files that are not replicated, but the vast majority of files are copied from the standby in order to reduce load on the master.

d0b6f78b20 More flexible configuration for databases
Master and standby can both be configured on the backup server and pgBackRest will automatically determine which is the master. This means no configuration changes for backup are required after failing over from a master to standby when a separate backup server is used.

f1412baccf Exclude directories during backup that are cleaned, recreated, or zeroed by PostgreSQL at startup.
These include (depending on the version where they were introduced): pgsql_tmp, pg_dynshmem, pg_notify, pg_replslot, pg_serial, pg_snapshots, pg_stat_tmp, pg_subtrans. The postgresql.auto.conf.tmp file is now excluded in addition to files that were already excluded: backup_label.old, postmaster.opts, postmaster.pid, recovery.conf, recovery.done.

f2b3dda647 Fixed an issue where a remote could try to start its own remote.
This is a better approach than 93320b8 (reverted in this commit) because it ensures that the remote type will be none so any functions that utilize optionRemoteTypeTest will work correctly.

This bug was only an issue when backup-host was not properly configured on the database host.

bd25223fd6 Rename test paths for clarity.
This was worked out as part of the test suite refactor [c8f806a] but not committed with it because of the large number of expect logs changes involved.  Keeping them separate made it easier to audit the changes in the refactor.

c8f806a293 Major refactor of the test suite.

41b27c0456 Protocol timeout option and keep-alive fixes.
* Fixed an issue where keep-alives could be starved out by lots of small files during multi-threaded operation and were completely absent during single-threaded operation when resuming from a previous incomplete backup.

Reported by Janice Parkinson.

* Added the protocol-timeout option. Previously protocol-timeout was set as db-timeout + 30 seconds.
* Failure to shutdown remotes at the end of the backup no longer throws an exception. A warning is still generated that recommends a higher protocol-timeout.
2016-06-22 18:01:18 -04:00
David Steele
012405a33b Closed #207: Expire fails with unhandled exception.
* Fixed an issue where the expire command would refuse to run when explicitly called from the command line if the db-host option was set.  This was not an issue when expire was run after a backup, which is the usual case.
* Option handling is now far more strict. Previously it was possible for a command to use an option that was not explicitly assigned to it. This was especially true for the backup-host and db-host options which are used to determine locality.

Reported by Chris Barber.

512d006346 Refactor database version identification for archive and backup commands.
Added database version constants and changed version identification code to use hash tables instead of if-else.  Propagated the db version constants to the rest of the code and in passing fixed some path/filename constants.

Added new regression tests to check that specific files are never copied.

0c320e7df7 Allow selective restore of databases from a cluster backup.
This feature can result in major space and time savings when only specific databases are restored. Unrestored databases will not be accessible but must be manually dropped before they will be removed from the shared catalogue.

9457e15347 New manifest format.
* All files and directories linked from PGDATA are now included in the backup. By default links will be restored directly into PGDATA as files or directories. The --link-all option can be used to restore all links to their original locations. The --link-map option can be used to remap a link to a new location.

* Removed --tablespace option and replaced with --tablespace-map-all option which should more clearly indicate its function.

* Added detail log level which will output more information than info without being as verbose as debug.
2016-04-14 22:50:02 -04:00
David Steele
18fd25233b New simpler configuration and consistent project/exe/path naming.
* The repo-path option now always refers to the repository where backups and archive are stored, whether local or remote, so the repo-remote-path option has been removed. The new spool-path option can be used to define a location for queueing WAL segments when archiving asynchronously. Otherwise, a local repository is no longer required.

* Implemented a new config format which should be far simpler to use. See the User Guide and Configuration Reference for details but for a simple configuration all options can now be placed in the stanza section. Options that are shared between stanzas can be placed in the [global] section. More complex configurations can still make use of command sections though this should be a rare use case.

* The default configuration filename is now pgbackrest.conf instead of pg_backrest.conf. This was done for consistency with other naming changes but also to prevent old config files from being loaded accidentally.

* The default repository name was changed from /var/lib/backup to /var/lib/pgbackrest.

* Lock files are now stored in /tmp/pgbackrest by default. These days /run/pgbackrest would be the preferred location but that would require init scripts which are not part of this release. The lock-path option can be used to configure the lock directory.

* Log files are now stored in /var/log/pgbackrest by default and no longer have the date appended so they can be managed with logrotate. The log-path option can be used to configure the lock directory.

* Executable filename changed from pg_backrest to pgbackrest.
