![]() The other option is to do it through SAP HANA COCKPIT.Įnable and Disable Encryption using SAP HANA Studio ![]() There are two ways in which you can enable and disable encryption, one is through SAP HANA Studio by use of various SQL commands or statements. If full protection in the persistence layer is required, SAP recommends that you use all the three backups. Backup encryption can be enabled for both backups written to the file system or backup written to the third-party backup tool through backint for SAP HANA interface.Ī third-party backup tool can also be used, in this case, you have a choice between SAP HANA Encryption or tool-side backup encryption. Backup encryption protects the contents of data backup, log backups and delta/ differential backups which includes snapshot backups as well. This feature is available from HANA 2.0 SP01. Like data volume encryption, log volume encryption also uses AES-256-CBC Algorithm and 256-bit page encryption keys. This feature is available only from HANA 2.0 SP00. Redo log encryption protects the log area i.e., the logs that are created under /hana/log/SID. ![]() This encryption uses AES-256-CBC Algorithm and 256-bit page encryption keys to encrypt and decrypt the data.Īs shown here, data is encrypted while it is being saved on to the disk, and it is decrypted when it is being loaded into the memory. This protects the data area on the disk, i.e., all the data that resides under /hana/data/ Here, all data changes are also captured in redo log entries.ĭata volume encryption is available from SAP HANA 1.0 SP12. ![]() However, data is automatically saved from memory to disk at regularly to ensure that the database can be restored to its most recent committed state. This helps in processing large data at a very high speed with less administrative effort. SAP HANA is an in-memory database, and most of the data is in the main memory for maximum performance. SAP HANA provides full support for data-at-rest encryption to secure your data. ![]()
