Using SAP HANA studio, connected to either the SystemDB or individual tenants, navigate to Configuration -> global.ini -> backup and set the values for the following fields:
|
Field |
Value |
|---|---|
|
catalog_backup_parameter_file |
File system location of the file setup for the tenant or database in Step 2. |
|
catalog_bakup_using_backint |
true |
|
data_backup_parameter_file |
File system location of the file setup for the tenant or database in Step 2. |
|
log_backup_parameter_file |
File system location of the file setup for the tenant or database in Step 2. |
|
log_backup_using_backint |
true |
|
paralell_data_backup_backint_channels |
Set to a value (up to 32) to which each tenant/database should run parallel data streaming operations through backint. Each stream in Backint will translate to a data stream to the FlashBlade. Note:
This value will be applied on a per host basis. If 16 parallel data backup channels are set in a 4 worker nodes environment , then the number of concurrent streams will be 32. |
Any values set for the System will then be applied to any tenants by default. To override this value set any specific values for each tenant.
It is possible to have the configuration file in a different location on each host and then to set this value on a per-host basis. The best practice would be to have this file located on the SAP HANA shared filesystem and all of the nodes to reference the same location.
