Incremential Backup to S3 possible with XtraBackup?

MySQL & MariaDB Percona XtraBackup

Hello,

we have been trying to get XtraBackup to Minio (S3) with incremential to run.

With xbcloud or --stream=xbstream we always get the same Error

error: backup named backupname already exists!

Is this possible with xtrabackup 2.4 or does it only work with Swift as

that is the example in the documentation?

Thanks for any help!

Andreas

@andrews2018 Make sure you are on at least xtrabackup 2.4.14. Also, the error seems very straightforward. Can you try picking a different name for the backup?

Hi,

At the documentation we show:

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

here, ${date -I}-full_backup is the backup name, which is treated as a PK for backups. Please choose a different name for each backup or append a timestamp to make it unique.
