Hi
The environment consists of a central location with two BE2012 servers A and B. A is also a CASO server.
The A and B BE2012 servers backup to two local Dell DR4000 storage appliances with OST.
The backup is then duplicated over to a DR4000 in a remote site, there is one BE2012 server C in the remote location with a tape library Dell TL2000.
The initial backup to DR4000 works fine.
The duplication to the remote DR4000 works fine. Although we had to disable verification since this copied the full backup back to the central site.
The problem is to get backup to tape working.
We have bought and installed the SAS to iSCSI module for the TL2000, as this seemed to be a requirement for sharing the tape library. But still not possible to share the tape library. We have ESO license, but haven't managed to share the tape library.
The problem is that we cannot include a duplicate to tape step in the backup jobs performed by A or B. C can backup to tape, but we have to manually select backup sets in the remote DR4000 storage and the duplicate to tape. This is very time consuming and not acceptable. In 2010 it was possible to create a standalone scheduled backup to tape job, but in 2012 it is not possible. It is sadly not possible to specify a different BE2012 server for the duplicate to tape step, which would have solved our problems.
We can probably add the tape library as an iSCSI device directly to the BE2012 A and B servers, but that would require all data to be sent over the WAN link. It sort of defies the purpose of having optimized deuplication transfer between central and remote site.
Is it really impossible to use the remote C BE2012 server to backup from the DR4000 to tape?
