What is the purpose of this parameter (VIXDISKLIB_FLAG_OPEN_UNBUFFERED)?

This is what is described in the guide:

For VixDiskLib_Open, The following flags modify the open instruction:

VIXDISKLIB_FLAG_OPEN_UNBUFFERED – Disable host disk caching.

How do I understand this sentence(Disable host disk caching)?

Thanks.

Backup jobs fail to use HotAdd and fall back to NBD transport method

We tried to backup a machine many times ,the machine occasionally failed to use HotAdd and fell back to NBD transport method。

The vddk log is following：

VixDiskLib:vixDiskLib ConnectEx:Advanced transport modes not available for opening moref=695. Cannot use advanced transport modes for <ESXi IP>/moref=695/695-snapshot-47：Invalid search specifier: moref:695.)

This happened occasionally.

Does any one have any idea of what could be going wrong here?

Environment: ESXi 6.5 and VDDK 6.7.3
