Could not authenticate with the NetWorker server as NMSAP HANA.

Question

Anyone backing up SAP HANA using NMSAP? :-)  If yes, I would appreciate your input on this one above.  I use NMSAP 8.2SP1 on HANA side, but backup seems to fails for what can be seen as following in backint raw log: 0 03/24/15 13:52:41  5 3 13 1 8913010 0 nsrd RAP critical Permission denied 70922 03/24/15 13:52:41  3 5 0 1697912576 53362 0 hdbbackint NSR error Backint exiting at with fatal error: Could not authenticate with the NetWorker server as NMSAP HANA. This is a bit strange and at the first look I would say quite obvious as it seems like some sort of impersonation takes place or index access and there is no right access rights.  I already had: user=*,host=$HANA_hostname user=*,host=$HANA_FQDN ... on DB admin and operator list, but that didn't help.  Then I added those to super admin list - but still no luck.  Licenses are not an issue (unless there is special SAP HANA backup license, but I'm not aware of that).

Just to update (and close) this thread... the issue here was that while I run NMSAP 8.2SP1 on SAP HANA, my backup server was still 8.0.x and that server does not understand this module (at least not for SAP HANA).  As soon as I changed it to use another server which was 8.2.SP1 it went well.

Hi may you share more details please? Are you using a user store key ? Is it a stand-alone or scaled out SAP hana enviroment? regards, -Nicola

Hi Nicolino,

Yes, we use user store key, but to my knowledge that is not used unless you run scheduled backup (that's why you call it in CFG and not profile file). I do get above when running manual backup DB backups from HANA studio (or autolog backups). This is standalone SAP HANA env so it is quite simple.

I don't know if this can help you but from guide: You have to grant the NetWorker server User Group resource privileges to the SAP user who performs the SAP HANA operations. regards, -Nicola

As noted in initial mail, this was done in form of user=*, host= .  Initially I did it for DB admin and operator, but afterwards I extended this to admin group as well - still the error is the same.
