Hii ,
I have a few queries on netbackup setup to integrate with Netbackup 7.5 / 7.6 & Datadomain ( DD) replication,
1. I had a setup with same master server name on PR -DR, netbackup 7.1 is used on both the sides and currently DD as VTL is used to replicate data, tapes are read at DR by sending "../db/images/ " folder to DR site, this was ok until we use Netbackup 7.1 as image database in 7.1 was flat file and no import was required if its placed in /db/images on my DR Master server.
2. If i want to upgrade to 7.5 i cant send the "../db/image" folder to DR as it is relational db and only option left with me will be AIR, but currently only MSDP supports AIR and my VTL based DD to DD replication wont support AIR.
3. If DD boost ( OST) is used for backup instead of VTL will i be able to use AIR as i suppose it will be supported only from Netbackup 7.6 version.
Attached a image to give a senerio of wat i want to achieve.
