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.

23a3911830 Stop using pg_xlogfile_name().
The pg_xlogfile_name() function is no longer used to construct WAL filenames from LSNs. While this function is convenient it is not available on a standby. Instead, the archive is searched for the LSN in order to find the timeline. If due to some misadventure the LSN appears on multiple timelines then an error will be thrown, whereas before this condition would have passed unnoticed.

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.

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.

f1e92804ce Docker container improvements.
* Containers now use a squid proxy for apt/yum to speed builds.
* Obsolete containers are removed by the <br-option>--vm-force</br-option> option.
* Greatly reduced the quantity of Docker containers built by default. Containers are only built for PostgreSQL versions specified in db-minimal and those required to build documentation. Additional containers can be built with --db-version=all or by specifying a version, e.g. --db-version=9.4.

eaa981c5aa Added execution cache for document generation.
Added an execution cache so that documentation can be generated without setting up the full container environment. This is useful for packaging, keeps the documentation consistent for a release, and speeds up generation when no changes are made in the execution list.

512d006346 Refactor database version identification for archive and backup commands.

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.

e430f0a054 Added --db-version=minimal option as default.
This change assigns each version of PostgreSQL to a specific OS version for testing to minimize the number of tests being run.  In general, older versions of PostgreSQL are assigned to older OS versions.

The old behavior can be enabled with `--db-version=all`.

a6a19e3735 Test directories are now located on the host VM rather than in the Docker container.
This change allows for easier testing since all files are local on the host VM and can be easily accessed without using `docker exec`.  In addition, this change is required to allow multiple Docker containers per test case which is coming soon.

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.

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.

1ce9961f8a Closed #183: Options --repo-path and --repo-remote-path ignored in archive-push.
Fixed an issue where the master process was passing --repo-remote-path instead of --repo-path to the remote and causing the lock files to be created in the default repository directory (/var/lib/backup), generally ending in failure. This was only an issue when --repo-remote-path was defined on the command line rather than in pg_backrest.conf.

f8b47997a3 Closed #127: More sanity checking for --delta restores
Added checks for `--delta` and `--force` restore options to ensure that the destination is a valid $PGDATA directory. pgBackRest will check for the presence of `PG_VERSION` or `backup.manifest` (left over from an aborted restore). If neither is found then `--delta` and `--force` will be disabled but the restore will proceed unless there are files in the $PGDATA directory (or any tablespace directories) in which case the operation will be aborted.

5c815e4fc0 Closed #58: Get catalog number for better tablespace copying
When backing up and restoring tablespaces pgBackRest only operates on the subdirectory created for the version of PostgreSQL being run against. Since multiple versions can live in a tablespace (especially during a binary upgrade) this prevents too many files from being copied during a backup and other versions possibly being wiped out during a `--delta` restore. This only applies to PostgreSQL >= 9.0 -- before that only one PostgreSQL version could use a tablespace.

02405e851c Closed #163: Document Generation Issue
Fixed an issue where document generation failed because some OSs are not tolerant of having multiple installed versions of PostgreSQL. A separate VM is now created for each version. Also added a sleep after database starts during document generation to ensure the database is running before the next command runs.

The WAL required to make the backups that fall outside of archive retention consistent will be preserved in the archive. However, in this case PITR will still not be possible for backups that fall outside of archive retention. 2016-01-20 17:24:44 -05:00

a9b9ec2492 v0.61: bug fix for uncompressed remote destination
* Fixed a buffering error that could occur on large, highly-compressible files when copying to an uncompressed remote destination.  The error was detected in the decompression code and resulted in a failed backup rather than corruption so it should not affect successful backups made with previous versions.
2015-04-21 09:45:03 -04:00
David Steele
5185d49873 v0.60: better version support and WAL improvements
* Pushing duplicate WAL now generates an error.  This worked before only if checksums were disabled.

* Database System IDs are used to make sure that all WAL in an archive matches up.  This should help prevent misconfigurations that send WAL from multiple clusters to the same archive.

* Regression tests working back to PostgreSQL 8.3.

* Improved threading model by starting threads early and terminating them late.
2015-04-19 17:53:29 -04:00
David Steele
b37d59832f v0.50: restore and much more
* Added restore functionality.

* All options can now be set on the command-line making pg_backrest.conf optional.

* De/compression is now performed without threads and checksum/size is calculated in stream.  That means file checksums are no longer optional.

* Added option `--no-start-stop` to allow backups when Postgres is shut down.  If `postmaster.pid` is present then `--force` is required to make the backup run (though if Postgres is running an inconsistent backup will likely be created).  This option was added primarily for the purpose of unit testing, but there may be applications in the real world as well.

* Fixed broken checksums and now they work with normal and resumed backups.  Finally realized that checksums and checksum deltas should be functionally separated and this simplied a number of things.  Issue #28 has been created for checksum deltas.

* Fixed an issue where a backup could be resumed from an aborted backup that didn't have the same type and prior backup.

* Removed dependency on Moose.  It wasn't being used extensively and makes for longer startup times.

* Checksum for backup.manifest to detect corrupted/modified manifest.

* Link `latest` always points to the last backup.  This has been added for convenience and to make restores simpler.

* More comprehensive unit tests in all areas.

David Steele
4bc4d97f2b v0.30: core restructuring and unit tests
* Complete rewrite of BackRest::File module to use a custom protocol for remote operations and Perl native GZIP and SHA operations.  Compression is performed in threads rather than forked processes.

* Fairly comprehensive unit tests for all the basic operations.  More work to be done here for sure, but then there is always more work to be done on unit tests.

* Removed dependency on Storable and replaced with a custom ini file implementation.

* Added much needed documentation (see INSTALL.md).

* Numerous other changes that can only be identified with a diff.

587bd1f8d9 v0.10: Backup and archiving are functional
This version has been put into production at Resonate, so it does work, but there are a number of major caveats.

* No restore functionality, but the backup directories are consistent Postgres data directories.  You'll need to either uncompress the files or turn off compression in the backup.  Uncompressed backups on a ZFS (or similar) filesystem are a good option because backups can be restored locally via a snapshot to create logical backups or do spot data recovery.

* Archiving is single-threaded.  This has not posed an issue on our multi-terabyte databases with heavy write volume.  Recommend a large WAL volume or to use the async option with a large volume nearby.

* Backups are multi-threaded, but the Net::OpenSSH library does not appear to be 100% threadsafe so it will very occasionally lock up on a thread.  There is an overall process timeout that resolves this issue by killing the process.  Yes, very ugly.

* Checksums are lost on any resumed backup. Only the final backup will record checksum on multiple resumes.  Checksums from previous backups are correctly recorded and a full backup will reset everything.

* The backup.manifest is being written as Storable because Config::IniFile does not seem to handle large files well.  Would definitely like to save these as human-readable text.

* Absolutely no documentation (outside the code).  Well, excepting these release notes.

* Lots of other little things and not so little things.  Much refactoring to follow.
