As data volumes continue to grow, effective data management and protection become critical. Database backups are a key component of data security, especially incremental backups, which are a fast and efficient way to keep your data up to date. why orc？
Optimized Row Column (ORC) is an efficient columnar storage format that is compatible with big data applications. It offers excellent compression ratios, fast read speeds, and support for complex data types. Because of these advantages, the ORC format is one of the preferred formats for data analysis and lakehouse solutions. Performance & Efficiency:The ORC format greatly reduces disk IO requirements and accelerates data reading speed through efficient compression, columnar storage, and vectorized queries, thereby improving overall query performance. Optimized Storage:ORC provides lightweight indexes and rich metadata, as well as support for partition pruning and flexible encoding of data types, all of which work together to reduce storage space and optimize data access. Ecosystem Compatibility:The ORC format is compatible with multiple big data tools and platforms, such as Hive, Presto, and Spark, ensuring good integration and data processing capabilities. why native?
Due to the advantages mentioned above, many vendors have chosen to support the ORC format, and the UhuDB of Even Number Technology also supports native ORC, which has more advantages in query performance than Parquet, and can also realize direct conversion with Hive data types. Compared with non-native ORC database vendors, this has the advantage of stronger data compatibility and higher flexibility. Pain points of traditional backup methods
The pain points brought by traditional backup mainly come from two aspects: First, full backup not only takes a long time, but also is huge in size, wasting a lot of storage space. The second is the offline problem, due to the inability to backup, resulting in the need for downtime for each backup, which has a greater impact on the business that requires high availability and 7*24 operation. Benefits of incremental backups
Compared with full backup and restoration, incremental backup and restoration reduces backup and recovery time and provides faster data recovery speed. At the same time, compared with the traditional offline backup (need to stop the database service), the backup reduces the downtime, the industry customers are more and more interested in the security of the data platform, and the incremental backup and recovery is becoming more and more necessary, which ensures the security of the data at the same time, reduces the platform maintenance cost, reduces business interference, and improves system availability. 
Advantages of Native Orc incremental backup
The high compression ratio of the ORC format means that even incremental backups require significantly less storage space. This not only saves on storage costs, but also reduces the need for bandwidth when transferring backup data over the network. Fast backup and recoveryDue to the columnar storage and lightweight indexing of ORC files, incremental backups can be performed quickly because the system only needs to process the changing columns and not the entire data set. This approach not only speeds up the backup process, but also speeds up the recovery process, as the required columns can be accessed directly at the time of recovery. Optimized query performanceVectorized queries in ORC format and rich metadata provide faster query performance. This means more efficient access to data when it is necessary to access data during the backup or restore process for verification or other purposes. As data volumes continue to grow, businesses need more efficient and reliable data backup solutions. The native ORC format provides a powerful storage format for incremental backups, reducing the time and cost of backup and recovery by improving compression and read speeds. UhuDB simplifies the backup management process with native ORC, and in the future, it is expected that incremental backup of native ORC will become a key component of data protection and backup strategies, helping enterprises consolidate their data assets.
