On-demand backup
KubeBlocks supports on-demand backups. You can customize your backup method by specifying --method
. The instructions below take using a backup tool and volume snapshot as examples.
Backup tool
The following command uses the xtrabackup
backup method to create a backup named mybackup
.
# Create a backup
kbcli cluster backup mysql-cluster --name mybackup --method xtrabackup
>
Backup mybackup created successfully, you can view the progress:
kbcli cluster list-backups --name=mybackup -n default
# View the backup
kbcli cluster list-backups --name=mybackup -n default
>
NAME NAMESPACE SOURCE-CLUSTER METHOD STATUS TOTAL-SIZE DURATION CREATE-TIME COMPLETION-TIME EXPIRATION
mybackup default mysql-cluster xtrabackup Completed 4426858 2m8s Oct 30,2023 15:19 UTC+0800 Oct 30,2023 15:21 UTC+0800
Volume snapshot backup
To create a backup using the snapshot, the backupMethod
in the YAML configuration file or the --method
field in the kbcli command should be set to volume-snapshot
.
# Create a backup
kbcli cluster backup mysql-cluster --name mybackup --method volume-snapshot
>
Backup mybackup created successfully, you can view the progress:
kbcli cluster list-backups --name=mybackup -n default
# View the backup
kbcli cluster list-backups --name=mybackup -n default
>
NAME NAMESPACE SOURCE-CLUSTER METHOD STATUS TOTAL-SIZE DURATION CREATE-TIME COMPLETION-TIME EXPIRATION
mybackup default mysql-cluster volume-snapshot Completed 4426858 2m8s Oct 30,2023 15:19 UTC+0800 Oct 30,2023 15:21 UTC+0800
caution
When creating backups using snapshots, ensure that the storage used supports the snapshot feature; otherwise, the backup may fail.
Backups created manually using
kbcli
will not be automatically deleted. You need to manually delete them.
