For large datasets and strict backup windows, you can adjust the backup speed by configuring the Maximum Concurrent Threads for Full Data Backup and Backup Network Speed Limit parameters of your backup schedule.
Concepts
-
Full backup concurrency
More concurrent threads increase backup speed but also have a greater performance impact on the source database. You can configure this parameter for all physical backup and logical backup paths.

Backup Network Speed Limit
This parameter limits the backup speed by throttling network bandwidth. The default value is 0, which indicates no limit. This parameter is supported only for the physical backup path for MySQL and Oracle.
NoteIf you only need to limit the network bandwidth for backups, set only the Backup Network Speed Limit parameter and do not modify the number of concurrent threads.
Procedure
Configure during creation
When you create a backup schedule, you will configure several options, including the maximum number of parallel threads for a full backup and Backup Network Speed Limit parameters located in the advanced settings. First, in the basic settings, set Full Backup Frequency to Periodic Backup, choose the days for the Full Backup Cycle, and specify the Full Backup Start Time. You can also enable or disable incremental backup and real-time log backup as needed. Then, in the Advanced Settings section, you can control the backup speed by adjusting the Maximum Concurrent Threads for Full Data Backup (for example, to 2) and the Backup Network Speed Limit (for example, to 0 MB/s to disable throttling). Other advanced options include backup read speed limit, incremental backup interval (default: 60 minutes), Enable Compression, and your choice of compression algorithm (such as GZIP).
Modify a backup schedule
On the backup schedule details page, click Backup Time and Advanced Settings to configure the maximum number of parallel threads for a full backup and Backup Network Speed Limit parameters. For more information, see Modify Backup Time and Advanced Settings.
