Decrease in volume backup
I am contacting you regarding a subject wich concerns a decrease in backed up volume of 20% for all client VMs since the upgrade of master and media from netbackup version 10.1.1 to 10.3.0.1 on 03/12/2024. The concerned environment only contains VMware backups (85 VMs), and 15 filer policies for which most of them there is no decrease observed. If I take the example of the VM X, before the upgrade, the full had a volume of 409GB, and after the upgrade, the volume decreased to 368GB, a decrease of 40GB was noted, for the same number of files and no client side modification was made. Another example, VM Y, before the upgrade the volume was 404GB, and after the upgrade it went to 364GB. Are you aware of this behavior for version 10.3.0.1 ? (no information in the release note) Is there a way to conduct an analysis for this topic ? especially since the 40GB drop is the same for all VMs. FYI: the upgrade from netbackup 10.1.1 to 10.3.0.1 was made just for the master and media, no modification for client servers. Master and media are under NBU 10.3.0.1 and RHEL 8.9Netbackup 7.6.1 failed to remove trusted master server
Dear fellows, We are still using a legacy Netbackup version 7.6 in Windows server. Recently we noticed failure of SLP replication to remote server. We did some research and tried to re-setup the trusted relationship between the two master servers. But with no luck. error message is below. I got a password error message if I use a wrong password. And the two servers have the same version. Did someone experience the same? and can share some thoughts. Thanks
Backing up data using 2 tapes drives at the same time
Hello We are on NBU 10.0.0.1 - windows (one server as master/media). We have a backup job containing like 30TB of data. The data are MS SQL *.bak files. We want to put this to tape. On the backup policy what is the best way to utilize 2 tape drives. I dont think we want to send multiple streams to the same tape drive correct? So the data needing backed up is on the network and its laid out like this: \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod1\ \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod2\ \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod3\ \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod4\ \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod5\ \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod6\ \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod7\ \\xxx-xxxxx.com\xxx\xxx_Backups\FULL\xxx123\Prod8\ I thought about splitting the 8 paths into two different policies - this I know will use two separate tape drives. What is the protocol or the correct attributes on a Netbackup policy (MS Windows) to set it up to use 2 tape drives instead creating 2 seperate policies?. If I just use one policy and have 2 streams going to one tape drive thats bad news for wear and tear on the tape drive correct? Is there a way to have a policy where their are multiple streams going to 2 different tape drives. Hopefully Im saying this correctly. BC
NBU client System requirements
Hello, I want to configure a FS backup in a windows client with a mount point configured. This mount point contains thousand of files and I want to use a client-side-deduplication. Does someone know where could I check the system requirements (CPU, RAM, disk) to have a good performance in the client? Thanks.
Backup Host SSL issue in Flex Appliance
Hi Folks, We got a Flex Appliance in which we set up 1 Primary and 1 Media, as want to back up some Nutanix VMs through the Cluster. We decided to go with the MediaServer instance as our backup host. The issue is when trying to add the Nutanix Cluster through the NBU Web UI, below the displayed error : "Credential validation failed. Provide correct AHV credentials, ensure that the backup host has Linux/Windows OS, verify that the backup host can access the AHV cluster, or the external CA is configured correctly." After some troubleshooting, we found the "nb_nutanix-ahv.conf" in the Media instance with the parameter "enable_ssl_validations" which is enabled by default. When disabling it, the Cluster is added successfully. Enabling it back, the integration of the Cluster failed again. So, we confirmed that the issue is related to SSL certificate. We tried to set the SSL communication following the NBU documentation, but it did not work, maybe we missed something (Below doc link) : https://www.veritas.com/support/en_US/doc/150073865-163074231-0/v147708883-163074231 Any idea how to fix this SSL issue with Nutanix ? Flex v 5.0 and NBU v 10.5. Regards.
