TECHNICAL UPDATE EDB Postgres Backup and Recovery Tool 2.4
WHAT’S NEW This announcement is notifying you of a new software release: EDB Postgres Backup and Recovery ToolⓇ 2.4
EDB Backup and Recovery facilitates and automates complete hot physical backups of your PostgreSQL or EDB Postgres Advanced Server database. It is a centralized server that can connect to and backup multiple local or remote Postgres databases.
In previous releases, EDB introduced capabilities such as block-level incremental backup, policy enforced management and naming of the backup files, compressed storage, and low disk space alerts.
What’s new in this release:
Users can now take multiple backups of PostgreSQL server versions 9.6 or higher simultaneously. If a backup is interrupted, it can be terminated automatically without the need to run the pg_stop_backup() manually.
Support for native packages for Debian 9 and Ubuntu 18.04 LTS.
The number of workers used for parallel restore can now be configured in bart.cfg rather than only on the command line.
'bart init' will now set archive_mode = 'on' if not already configured.
If a user wishes to add a new server to BART without configuring archive_mode and archive_command on the server, 'bart init' may be run with the new '--no-configure' option.
BART 2.4 now has a Quickstart guide. The guide enables users to install and configure BART, and take a full and incremental backup quickly. For details, please see the EDB Postgres Backup and Recovery Quickstart Guide.
BART installation is now documented in a separate guide titled EDB Postgres Backup and Recovery Installation and Upgrade Guide to improve readability. Refer the EDB Postgres Backup and Recovery Installation and Upgrade Guide for details.
Defects corrected in this update:
Fixed multiple problems with parallel backups taken using the ‘tar’ format. [ BART-457 ]
Removed erroneous sanity check that could cause restore failures. [ BART-359 ]
Prevented wrong backupinfo file from being generated when a tablespace is dropped during an incremental or parallel full backup. [ BART-401 ]
Prevented possible backup failure with concurrent relation drop. [ BART-436 ]
In rare cases, a backup operation could report success and then also report failure; prevented that from happening. [ BART-406 ]
Ensured a clear error message is displayed when an incremental backup is attempted on a standby server. [ BART-200 ]
Adjusted order of arguments to ‘tar’ to avoid version-dependent behavior. [ BART-443 ]
Allowed an incremental backup to be restored without specifying a restore path for tablespaces which had been dropped by the time of the incremental backup. [ BART-416]
Fixed a crash in 'bart check-config' which occurred when the target directory is not writeable. [ BART-399 ]
Ensured error is generated if integer-valued parameters in bart.cfg have invalid values. [ BART-115, BART-366, BART-269 ]
Bart check-config now accepts wal_level = 'hot_standby' as a valid configuration. [ BART-422]
Bart displays an error immediately when a non-integer compression level is specified, instead of after copying all of the backup files. [ BART-151]
Fixed batch_size default so that it is consistently 3/8 of a GB in both the server and global sections [ BART-302 ].
