Backup can be performed normally even without using a backup disk.
In the case of MariaDB, using a backup disk is optional.
However, using a backup disk offers the following advantages:
* Available for both single-mode and cluster-mode (HA) MariaDB services.
- Improved data storage stability:
Backup files are stored in the backup disk, so they do not affect the usage of the data storage.
This eliminates issues related to exceeding data storage thresholds due to backup files.
- Reduced restore time:
Backups from within the last day are stored in the backup disk, enabling faster restoration.In cluster-mode (HA), it also shortens the recovery time of the slave node.
We recommend using the backup disk for improved backup and restore performance.
