Unity NDMP incremental backup always do a full backup
Networker version 9.2.1.0
Unity 500
I configured Networker to do backup from a NAS server Unity via NDMP protocol. Full backup every sunday and incremental backup in the others days, but Networker do full backup every day.
The configuration client is this:
Backup command: "nsrndmp_save -T dump"
Application information:
"BUTYPE=dump
DIRECT=Y
HIST=Y
UPDATE=Y
SNAPSURE=Y
USE_TBB_IF_AVAILABLE=N
NSR_PS_DEBUG_LEVEL=0"
Any ideias why Networker is performing a Full backup?

Hi Fabio,
is see that you are using Unity which supports Token based backups but have decided not to use the TBB. You are using USE_TBB_IF_AVAILABLE=N but still are getting the message that the backups is taking a full because token based backups is not available!
Is this a new configuration?
Has the incremental backups worked before ?
You could enabled the TBB and see if that does any good.
You can also attempt to use application parameter ATTEMPT_TBB=Y or ATTEMPT_TBB=N and see if this helps in anyway.

You're right. I created the client with default settings, TBB was disabled for default.
After use USE_TBB_IF_AVAILABLE=Y, incremental backup ran fine.
Thanks.
