UNSOLVED
Hello,
you can find all these informations in the official documentation, why do you not look at it first?
Probe start time - The probe start time specifies the time when the probes will begin to run. The start time is specified by a 24 hour clock (hh:mm). For example, 23:00 would start the probing at 11:00 pm.
Probe end time - The probe end time specifies the time past which the probes will not be run. The end time is specified by a 24 hour clock (hh:mm). For example, 5:00 would stop the probing at 5:00 am.Client direct - A client direct backup bypasses the storage node and writes directly to the target disk device during a scheduled backup of the client. The target disk device can be a Data Domain or an Advanced File Type (AFTD) device. When enabled, client direct is attempted on the target disk. If a client direct backup is not possible, a storage node backup is attempted. This attribute is supported on 8.0 or later clients. For pre-7.6.1 clients, leave this attribute enabled (default setting). Although client direct is not supported on pre-8.0 clients, disabling this attribute may cause the backup to fail. DD Boost and data deduplication
NetWorker client software uses DD Boost components to integrate with DD Boost logical
storage devices on Data Domain systems and perform data deduplication backups. Data
deduplication is a type of data compression that removes duplicate information to
dramatically reduce the amount of backup data sent to the storage devices and reduce
the bandwidth required for the data transport.
The NetWorker client software includes two DD Boost software components to enable
deduplication operations on the client:
l The DD Boost library API, which enables the NetWorker software to communicate with
the Data Domain system.
l The distributed segment processing (DSP) component, which reviews the data
already stored on the Data Domain system and adds only unique data to storage.
@bingo, question here is about parameters for probe based group and not savefs probe. It is there for some time and you can find some details discussed in Using probe based backups in NetWorker « NetWorker Blog
'probe' is the server-initiated process which will be run at the beginning of an 'automatic' (server-initiated) backup.
The NW server checks whether it can reach the client and prepares a 'worklist' (whatever will be backed up depending on the current settings and the savetime (the date)).
The actual command involved is savefs.

Hi,
as far as I understood, the probe start time and probe end time defines the time slot within the probes are checked (or evaluated).
DD boost is an EMC protocol (provided by the DataDomain device) which is using deduplication to eliminate redundant blocks from transfering to the backup device.
If a NetWorker client is using the DDboost protocol this function is called client direct. If client direct is enabled, the NetWorker client communicates direct with the DataDomain device (the backup data are bypassing the NetWorker storage node).
