Percona XtraBackup 2.4.14

Percona is glad to announce the release of Percona XtraBackup 2.4.14 on May 1, 2019. Downloads are available from our download site and from apt and yum repositories.

Percona XtraBackup 2.4.14 enables saving backups to an Amazon S3 storage when using xbcloud. The following example demonstrates how to use an Amazon S3 storage to make a full backup.

$ xtrabackup --backup --stream=xbstream --extra-lsndir=/tmp --target-dir=/tmp | \
xbcloud put --storage=s3 \
--s3-endpoint='s3.amazonaws.com' \
--s3-access-key='YOUR-ACCESSKEYID' \
--s3-secret-key='YOUR-SECRETACCESSKEY' \
--s3-bucket='mysql_backups'
--parallel=10 \
${date -I}-full_backup

All Percona software is open-source and free.
