Percona XtraBackup 8.0.26-18.0

Percona XtraBackup enables MySQL backups without blocking user queries, making it ideal for companies with large data sets and mission-critical applications that cannot tolerate long periods of downtime. Offered free as an open source solution, it drives down backup costs while providing unique features for MySQL backups.

Improvements

  • PXB-2477: The xbcloud should retry on error and utilize incremental backoff (Thanks to Baptiste Mille-Mathias for reporting this issue)

  • PXB-2580: With the xbcloud binary, a chunk-upload on an SSL connect error to S3 was not retried (Thanks to Tim Vaillancourt for providing the patch)

  • PXB-2317: Remove the obsolete LOCKLESS binary log functionality since the performance_schema.log_status table is now used to get the log information on all the storages without locking them

Bugs Fixed

  • PXB-2101: The Prepare step fails due to duplicate Serialized Dictionary Information (SDI) (Thanks to Fungo Wang for reporting this issue)

  • PXB-1504: The FIND_GCRYPT macro is broken (Thanks to Maxim Bublis for reporting this issue)

  • PXB-1961: The Prepare step of a full backup fails for encrypted tables with a generic error

  • PXB-2585: XtraBackup fails to backup archive RocksDB Write-Ahead Log (WAL) files
