Multiple vendor OST in Backup Exec?
Does BE support OST from multple vendors? A 2016 post implies that it was supported, so I just want to make sure that's still true for BE 21. We've set up a new Dell Data Domain DD6400, but we need to keep the old Quest DR4100 around for a few more months to restore from if needed. Thanks.

HP StoreOnce 5100 w/ OST Driver 4.1.1.1 and job slowness?
We have been running Backup Exec 16 on 2012R2, with the OST 2.01 driver for about 5 months. I was noticing some tape not found errors, and also noticed the OST driver was updated to 4.1.1.1 and it included Server 2016 support and other additions. I updated one of our BE servers to it, and noticed the tape not found errors no longer randonly show up, however our backup times have doubled, and in some cases tripled. Same for the duplication processes as well. For both physical and virtual servers. Has anyone been noticing this? HPE just suggests allowing more streams per backup, but I think they don't realize that is a Netbackup feature, and not Backup Exec.

DLM issues - Duplicated backup sets
Hi all, I have a complex issue with regards to DLM and duplicated backup sets I am hoping you may be able to help with. My current setup is as follows: We have two sites; Production and DR At each site we have a DataDomain setup as OST storage The production BE implementation is a CASO server and DR the slave. Each night we backup the production servers to the Production OST device and then duplicate to the DR OST device. The problem we are facing is that once a backup set has been duplicated to the DR OST device, both the production incrementals and DR incrementals become dependant on the last duplicated Full backup. The Full backups at the Production site display no dependant backup sets even though incrementals have since been taken. The issue with this is that when full backups expire on the Production OST they are removed regardless of there being any incremental backups still on the Production OST which would be dependant on the Full backup. Usualy DLM would recognise that there are dependent incrementals and expire but not delete. However as the dependent sets are being associated with the duplicated copy on the DR OST this does not happen. This means that in the event of a restore, I would have to rely on the DR OST backup sets which are not local to site, meaning a slow restore. I have a case raised with Veritas support who have replicated this issue in the lab and said this is "by design". I have asked them to tell me the logic behind this but whilst I wait, I was hoping I might get some insight here and also any particular workarounds (other then making my incrementals expire before my full set). Thanks in advance!

BE15, DataDomain optimized replication & replication to tape
We have two sites with two MBES servers on each site and a single DataDomain on each site. One site has a tape library. We also have a CASO server controlling the show. We wish to replicate backups to the DD on the other site, and write the monthly backups to physical tape (located in only one site). Site1: 2xMBES +DataDomain Site2: 2xMBES+DataDomain + Library + CASO We've got the DataDomain accessed through OpenStorage (DDBoost client) all fine. I discovered that both DD have to be presented toall BE servers - so that BE can perform a DDBoost optimized replication from one DD to the other. We configured two Server Pools, so when a backup is performed on Site1, it can be directed to just one of the Site1 MBES, and the same at Site2. Backing up to DD and replicating to the other site works fine - however I'm having issues when trying to replicate to the tape library in Site2. This works OK for backup jobs that start in Site2 since the MBES in Site2 can see both DataDomains and the tape library. However - for backups in Site1, when I try and do the same, it doesn't let me do this due to none of the Site1 MBES having access to the tape library: "The Backup Exec server specified and the device/storage devices pool specified do not share any devices". What I would like to do is configure the backup & DD replication to be performed by the Site1 Server Pool, but the replication to tape to be done through the Site2 Server Pool. How can this be done?

How to duplicate backup data on OST device across site
