Share Best Practices

Hello Commvault Community,We are planning to migrate to the latest Commvault version, which no longer supports V1 indexing. As we prepare for this transition, I would like to gather insights and advice from those who have already gone through this process.Questions:What are the essential steps to ensure a smooth migration from V1 to V2 indexing? What are the critical considerations to keep in mind during the migration? Are there any known issues or pitfalls that we should be aware of? What best practices can you share for managing the migration effectively?Any detailed experiences, tips, or documentation links would be greatly appreciated. Thank you in advance for your support and guidance!

We will be adding a new VMWARE Envrioment V8 to our Commvault backup; we use Intellisnap backups at the moment, however, in V8 we are using Datastore Clusters; how does that impact Intellinsnap and would the process be same Adding Storge snapshot engine to Commvault Setup Subclient and use the snap engine however, would there be impact if say due to storage DRS a VM moves from one datastore to another. I have seen with Intellisnap (Nutanix) if you have a VM in 2 Datastore it fails the whole job; yet to runinto this senario with pure but how would this work?  

Does anyone have any information from Commvault regarding CommServe support for windows server 2025?I have tested it in our lab and it seems fine. 

Hi Team,I’d like to know if there is a way to run PostgreSQL, MariaDB and MSSQL backups from scripts on the clients similarly to RMAN.I founf the Save as Script option on the Subclient, but we woud like to use our own commands (pg_dump  ${database}) and still make sure the backups are witten to HSX.ThanksFrancesco

Hi:Which is the best way to migrate from Commvault to Commvault Cloud? (Metallic) I have been told that there is not an utility to do it and that should be a restore and backup process just like as going from another software to Commvault, but I guess that a lot of customers may have the same requirement.Any thoughts will be appreciated.Best,Paul

I have created a new subclient policy but instead of using this default subclient i created a new sublclient to take backup of only selected extensions and assigned to all 100 laptops.now when i created a schedule policy and assigned schedule policy to a laptop client group .the backup us being run for the default subclient as well as the new one which i created.i have disbabled default subclient from policy by “activity control” but still the schedule policy executes job for both and its causing lot of failures in my job and confusion during restore.raised case with support ( 250331-339) but they are not able to do anything from last 10 days. 

Hi, I’m having problems with a Commvault Oracle Data Guard configuration. I have a Data Guard pseudo-client which handles the backups for the environment which has 2 databases on 2 different hosts: dbhost01 and dbhost02. It is configured to run backups on the primary node. A few days ago a database failover happened (from dbhost01 to dbhost02), it was successful, so no issues with that, currently the primary database is on dbhost02.My problem is that since the failover the commvault backups cannot run, because it is still trying to reach the database on dbhost01 (which is shutdown). It sees that the database on dbhost02 is open, but does not even try to start the backup there.What is the correct way to configure this? The whole point of having this Data Guard configuration in Commvault is that we don’t have to modify anything in commvault when a failover/switchover happen, so I’m looking for a solution that provides this. Thank you for any t

Hi all, We have a Server with Commserver and MA installed on it and I want to renewal on a new server. The MA have a local Disk Library of some TB of backups. I’ve refered the commvault documentation of Commserver Hardware Refresh but  I still haven't understood how migrate local disk library data to new hardware. Could any help me with some ideas how do this migration? Actual server has local disks in RAID 5 (disk library), that here are my backups. New server has local disk in RAID 5, to received that migration.  Regards!

Does anyone have in their Windows Application Event Log of your Media Agent Server any event id’s 1001 that look like this:Fault bucket 2119584666510853566, type 5Event Name: RADAR_PRE_LEAK_64Response: Not availableCab Id: 0Problem signature:P1: CVODS.exeP2: 11.280.1000.1507P3: 10.0.17763.2.0.0On mine, the event name and the exe changes but does repeat. Sometimes it’s VSBK.exe or a random Windows exe.I used to have a ton of these.Present day it’s much less. Last year the Application Event log was littered with these and the Media Agent Server became unusable.  Support was at a loss. It might be easy to say there was a hardware issue. This server was in service from 2019 - 2024 and operated 24x7 without issue.Since that terrible week last year the MA was migrated to a different server to get backups going again. These app crashes in the Application Event log still occur on the new server, but they are few a

Hi Team,We purchased a Huawei Dorado 18000 v6 device onsite to use in Commvault backups. We want to configure and define this device as a Nas Library, but some questions came up to my mind.- Are there any Best Practices to follow when defining a NAS Library to Commvault?- What should we determine as Block Size on the storage side?- Would it be more logical to set a quota when creating a NAS share on the storage side or to use the "Do not Consume more than" option on Commvault?- Would it be more efficient to create a library with many NAS shares, for example 5*10TB=50TB or 1*50TB=50TB?- If I am going to use 3 Media Agents, would it be more logical to create a DDB with 3 partitions and place each partition in the relevant MA? Best Regards.
