TimescaleDB is an open-source time-series database optimized for fast ingest and complex queries. It is built on top of PostgreSQL, providing the reliability and robustness of PostgreSQL with additional time-series capabilities. TimescaleDB is widely used for monitoring, IoT, and real-time analytics applications.
When attempting to restore a TimescaleDB database from a backup, you may encounter a failure with the error code TSDB-049. This error typically manifests as an inability to complete the restore process, potentially accompanied by error messages indicating corrupted files or procedural issues.
The error code TSDB-049 indicates a failure during the restoration of a TimescaleDB database. This can be due to corrupted backup files or an incorrect restore procedure. Ensuring the integrity of your backups and following the correct steps is crucial for a successful restoration.
Common causes for this issue include:
Before proceeding with the restore, ensure that your backup files are complete and not corrupted. You can use tools like pg_verifybackup to check the integrity of your PostgreSQL backups. For more information, refer to the official PostgreSQL documentation.
Ensure you are following the official TimescaleDB restore guide. The basic steps include:
systemctl stop postgresql or the equivalent command for your system.pg_restore or pg_basebackup, depending on your backup method.systemctl start postgresql.For a detailed guide, visit the TimescaleDB Backup and Restore Documentation.
Ensure that the TimescaleDB version used for the backup matches the version you are restoring to. Incompatibilities can lead to restore failures. You can check your TimescaleDB version using the query:
SELECT default_version, installed_version FROM pg_available_extensions WHERE name = 'timescaledb';
For more on version management, see the TimescaleDB Update Guide.
By ensuring the integrity of your backup files and following the correct restore procedures, you can resolve the TSDB-049 error and successfully restore your TimescaleDB database. Always refer to the official documentation for the most accurate and up-to-date information.
