The configuration file path for the XBSA App is /etc/sf-vmbackup-app/sf-vmbackup-api.yaml. The functions of some key options are described as follows:

Port: The port that the XBSA App listens on.

BackupConfig.TransportMode: Backup transmission mode. The default is nbdssl. The nbd mode does not encrypt backup data during transmission. If backup performance is a priority, you may switch to nbd mode.

BackupConfig.BackupChainMaxLength: Maximum incremental backup chain length. The default value is 30. An excessively long backup chain can significantly reduce backup and restore performance. This setting usually does not need to be modified.

BackupConfig.SkipZero: Whether to enable skipping of zero data blocks. Enabled by default. This option improves the transmission efficiency of zero data and generally does not require modification.

BackupConfig.BackupClusterSize: Backup block size. Default is 64KB. This is a reserved configuration item and should not be modified.
