The cluster recycle bin stores released PolarDB clusters. This topic describes the principles, retention periods, and billing for the cluster recycle bin of PolarDB.
Usage notes
When you release a cluster and choose to retain its backup sets long-term, the backup sets are automatically moved to the cluster recycle bin.
Backup retention rules in the cluster recycle bin vary by edition:
For Enterprise Edition clusters, level-1 backups are asynchronously converted to level-2 backups at approximately 150 MB/s. This conversion incurs a small fee.
For Standard Edition clusters, a small fee applies to level-1 backups.
For clusters in the cluster recycle bin, you can either restore the released clusters or permanently delete the released clusters.
Retaining backups may incur a small fee. You can delete backups at any time to reduce costs.
If your Alibaba Cloud account payment is overdue, the backup restore feature for PolarDB clusters in the cluster recycle bin is disabled. The feature is automatically re-enabled after you add funds to your account.
If your Alibaba Cloud account payment is overdue for more than 14 days, the system automatically releases the backup sets in the cluster recycle bin. The data is permanently deleted and cannot be recovered.
Retention periods
After a cluster enters the cluster recycle bin, its backup files can be retained for a maximum period of 7,300 days.
Billing
Billing rules for retained backups vary by edition:
For Enterprise Edition clusters, level-1 backups in the cluster recycle bin are free of charge. Fees apply only after they are converted to level-2 backups.
For Standard Edition clusters, a small fee applies to level-1 backups.
