More Information
Summary:Various systems and methods to efficiently store backups of partitions of a database are disclosed. An indication to take a current snapshot of a partition of the database is received. A log size and operation type statistics are determined for a portion of the change log for the partition. A snapshot type is determined for the partition based at least in part on the log size and the operation type statistics, where the snapshot type specifies a log-based snapshot or a full snapshot. The snapshot is stored as metadata indicating a point in the change log if the determined snapshot type is log-based snapshot or stored as complete data of the partition if the determined snapshot type is full snapshot.
