Share Best Practices

We are currently looking to go Tapeless and I realize that some of our Backups are not setup as best they could be.  One of the places is backup of SQL Databases.  Currently we have the SQL Databases backed up by the SQL Program itself and then we make a backup of the .BAK files.  This adds ALOT of extra time for restores as we have to restore the BAK and then restore the BAK again inside SQL.  I have been told when Commvault was first installed years ago we tried using Commvault for the full backup of the DB’s but it was very slow and had issues.  I am hoping with the newer technology things will be better.  My question is what are best practices.  I have been reading through the Docs from Commvault for SQL server and it seems straight forward, but I am not sure if the backup window needs to be when no-one is using the DB, or if the DB needs to be locked for a few hours as it backs up.  We normally have processes running against the DB’s most of the day and night.  I am sure many c

Hi all-I have two commcells (primary and disaster recovery) and 4 media agents (2 primary, 2 DR), al running Windows 2012.  I will be spinning up a new 2019 environment that I plan to run in parallel until I have everything running on 2019 with no issues.  Question: is this the best solution?  I’ve seen a couple of nicely detailed posts here about in-place upgrades but since I am also setting up new media agents in both locations, I figure I’d just spin up a new 2019 server for the Commserve in both locations. Does anyone have any pointers or guide on how to do this in the least painful way possible?  I’ve been reading various kb articles as well, but I would love to hear from anyone who’s done this so I can get an idea of what’s ahead of me.  Thanks everyone.

Hi there, I would like to ask you if it is better to have dedicated VSA proxy VM or if the VSA role should be taken by Commserve server? What should be taken into account? Let’s say, there is a smaller environment roughly said 20TB of data and only VMs. Unfortunately, I didnt find any recommendations or best practices.

Hi, We’re planning to use Commvault with on-prem disk storage that has the WORM feature enabled. At this moment, we know that when using WORM on the storage side, Commvault WORM must be also configured (WORM Copy property). I had an open Incident 221229-281 to describe additional settings. The support reply is to run a workflow, but this is specific to Storage Pools. That is not our case. We’re planning to use WORM with Secondary Copies with deduplication. We can’t use Storage Pools right now, because we already have some copies bound with a Global Deduplication Policy. What other settings do we need to? Below I have a list of things that need to be done.Could you confirm if is this correct and add something to it if necessary? Check WORM Copy property  Disable the CV

Hi Guys, We are using partitioned DDBs running on 2 media agents in the environment on the Azure VMs. Our current Deduplication setting on GDSP level is to seal and start a new DDB in case of any DDB corruption instead of Recover Pause and Recover current DDB. Also the option to “Allow jobs to run to this copy while at least 1 partition is online” is not selected.  Just wanted to check what is the best practice for partitioned DDBs as per Commvault.CS : Azure VMPrimary Library : Azure BLOBSecondary : Metallic

We have 9 Hyperscale Appliances and an offline NetApp NAS Storage. The offline storage is used on Mondays only for Aux copy and path on Hyperscalar Appliances are mounted using NFS.Now Offline storage library is 90% full and we are in process of expanding the storage. As per existing design NetApp NAS is mounted on all 9 HSs. The new storage is HP MSA SAN storage supporting ISCSI. We have allocated the new disks to HS using ISCSI and mounted them on all 9 HyperScalar Appliances as per existing design.I manually tested by creating a file on one of the HS and then tried to remount the mount path on other HS. While doing so the mount point showed corruption  and had to clean the FS. My concern is whether we have taken a right approach and there should to a change in design like adding an additional server to use NFS on 10G network. Recommendations are much appreciated. 

Hi Fellas, Has anyone used the key below, is it safe to use? Will it have a negative impact on the server or the application running on it?I'm thinking of using this because while taking a backup on one of our servers, clbackup and cvfwd processes are using high cpu. Compression+dedupe are on media agent.By using this key, I aim to limit the max CPU usage of these processes, will the correct usage be as follows?https://documentation.commvault.com/additionalsetting/details?name=sSDTHeadMaxCPUUsage  Best Regards.

We need to stage our customers databases. On CS on windows we use CSrecovery assistant and it it is easy. Staging A Commserve on Linux database I tried the document:https://documentation.commvault.com/2022e/expert/142005_staging_commserve_database_on_another_commserve_linux_host.htmlThe staging works as described with one exception, admin password was not resetted. That means I cannot open commcell consoleCSrecoveryassistant.log shows “skipping admin password update as per registry hook”

Hello, I wanted to know if I can customize the default reports from Commvault. As an example the fall Behind Secondary Copies. I find "10 days for critical" too much and would like to customize these benchmarks 

Important note: do not modify CSDB data and modules, just use READ operations only.You can refer official documentation to explain part of CSDB information as CommCell Views, but no more information as of now. So it's slightly hard nowadays to generate your own reports and/or workflows directly refer to CSDB tables which contain all CommCell information.This article provides simple examples to retrieve data by your own.In the first place, you can run any SQL queries from Microsoft SQL Server Management Studio or DBeaver as you like (and recent Linix CommServe environment, still there must be some tricks to gain access, though).To keep your activities safe you need to keep uncommitted read from any table as one

The web console was created to solve a number of issues imposed by the Java console.It also slots right into the paradigm of web and rest api communication. That said the early console was… bad… like really bad.But over the years it has gotten better and it keeps getting better.So my suggestion for people who are new to commvault is to use the webconsole as it is intended to replace the java gui, the Java GUI has to drag along the all the cruft from the inception of the product, making it so that some things don’t even make any logical sense as presented in the Java GUI, also many new features simply do not get back ported to the java GUI. At one point, the Webconsole was a poor substitute for the Java GUI, but I would strongly suggest that you foster the habit of using the web console. There will always be the graybeards that stick to the old ways, and while there are definite benefits to doing but there are also downsides, th

Following best practices is important for any aspect of our product, but this is especially important with regard to the Deduplication Database.  A well-specced Media Agent that meets and exceeds our hardware recommendations hosting a DDB that is configured properly can achieve incredible feats of space savings and backup performance.  Conversely, without proper planning and optimal configuration the performance and storage usage can be negatively impacted. Since the inception of deduplication in Commvault one of these Best Practices has always been that Extended Retention should not be used on a DDB being used for a Primary Copy.  To prevent a DDB from becoming too ‘bloated’, our recommendation has been to segregate long-term retention into its own DDB, leaving only Basic Retention on your Primary Copy.  Although it may appear obvious that longer retention means a larger DDB, the true reason for this may not be immediately apparent.

SAP HANA Logcommandline Backup is invoked from HANA side (HANA Studio configuration), it automatically converted to Commvault backup jobs and normally there's nothing we should do, running every 15 minutes by default per HANA's setting.But this job is slightly different from the other "normal" jobs, when any interim errors, like disconnection of networks, shortage of Commvault resources (typically # of streams on libraries or strage policy copy level), the job would fail.As mentioned above, this job would repeat every 15 minutes (by default), so any failure would be recovered quickly so typically end user won't lose any of data. But sometimes there's another issues might be at CS/MA side, hard to keep watching even setting up alerts, job monitoring, etc. This is to list up all failure reasons from CSDB quickly (for a Japanese customer), if any suspicious errors identified you can dig into the specific job for detailed research:

 Introduction As a part of backup infrastructure implementation, using GCP (Google Cloud Platform) shared VPC’s (Virtual Private Cloud) to come up with multi-NIC media agent setup for CommVault infrastructure. This opened doors to backup data from one tier and restore the same across another tier. This has reduced the overall time and cost to migrate data to a separate  client over the GCP network. It also ensured that there is network isolation between production and non-production tiers as no additional firewall ports had to be opened to transfer the backups.Media agent in GCP with two VPC’sBelow is the screenshot from GCP console which shows Commvault media agent has two NIC’s associated with different subnets from two separate shared VPC’s.Restore using Commvault multi-NIC media agentBelow is a high level d

Hello, What is the best way to backup NFS export presented by EMC VNX Storage ?

Hello, We are getting slow throughput for VMware backups using intellisnap. Around 150 gb per hour with 5 readers.Data store is on NetApp and VSA/Media agent is VM.It is currently using NBD transport mode.Can hotadd or another transport mode be used and will that be faster? Is there any other best practice? 

Just looking for good ideas here.

Often we see cases where Check Readiness is failing or backups failing due to communication issues. Whether these clients be Media Agents, VSA Proxies, Exchange servers or Linux FS.This article will cover common issues that, we, as support frequently come across in tickets that are raised.Check readiness is a simple tool that can be run from the CommCell or Command Center that does a network check to ensure that the Commvault Ports are opened and listening.The first things we want to check:Are Commvault services running on client? Is DNS resolving? Are the required ports opened? Is Windows firewall enabled? 

Hi all.Just wanted to share here that although Okta is not officially supported we have been able to get it work for 2FA as a basic Other standalone time-based PIN. We set 2FA against a group and then place users in one at a time. I wrote a couple of docs about it if anyone would like the details.
