Media Agents can be physical or virtual?

Dumb Question, but I don't want to have to have my systems team argle bargle. Media Agents have to be physical servers, correct? I am assuming there shouldn't be a reason why it cannot be a virtual machine, but before I put my foot in my mouth (tasty btw) I want to see what the community best practice is.

cvfwd errors between commserver and media agent - whitelist

This just started a week or so ago. The Commserve shows libraries for a particular media agent server as “marked not ready”. Looking into the cvfwd file on both servers shows the following.On MA:”ERROR: Connection from <commserver. to localhost:50580 is being denied due to not matching a configured whitelist and due to no services listening on this port.”There are actually 4 error lines for each instance. “validate(), “do_connect_client90(), and two with “Client connection failed….”In the cvfwd file on the commserve, there are similar ERROR messages.After a minute or two, the libraries are “now marked ready” and I can see an established connection on that port (50580).Do not see this on other MA servers. The MA and Commserve server are in the same IP subnet.Does not appear to be traffic related, as this will occur while nothing is going on between them.And does not appear to be impacting functionalityAny suggestions or hints?.

Create backup copy from NetApp (backup target) to another NetApp using SnapMirror

Hi all,We have Pure as a primary storage. Using CommVault (via IntelliSnap) we backup data from it (Snap Copy). Then we mount snapshots to Media Agent (MA) and perform backup copy (Primary) from snapshots to our primary backup storage - which is NetApp (NA1). We have another similar NetApp in different location (NA2).Question - is it possible to create additional backup copy from Primary copy using SnapMirror\SnapVault?It is possible to create additional Snapshot Copy but you have to use NetApp as a primary storage. Which is not a case.So we want to have second backup copy (NA2) and it should be available as a source for restore for clients. And we don’t want to utilize our MAs and network when NetApps can do everything themselves.

slow backup and restore with Catalys HPE

Hello Commvault, we have been working with Commvault and Catalys HPE for 2 months since before we used Data Protector from Microfocus and Veeam. At first the performance was incredible but as the backups continued we noticed that the backup and restore speed dropped noticeably, reaching the point of restoring VMware VMs over SAN at a speed of 50GB/hour which is extremely slow. I reviewed the documentation provided by Commvault and also by HPE and the only strange thing I noticed is that the number of objects we had in the catalys stores when we used Data Protect or Veeam were from 2000 to 5000 and now with Commvault their stores store more of 40,000 objects and this does not affect the performance. I see that 30% are index objects that run at 1 pm. Please have any suggestions and if you have had a similar problem before.

Is versioning (on s3 compatible bucket/namespace) even relevant for Commvault Backup of VM, SQL, Oracle DB workloads to S3 Compatible Storage.

HiI created a backup job for a VM with deduplication enabled at subclient level selected as “on the client”. Enabled Versioning on the bucket configuration. Took FULL backup twice. But it didn’t create versions of the same backup.Later, I ingested some files inside the VM and retook the FULL backup. Still, No versions created at the bucket level.I then disabled deduplication at the subclient level, retook the full VM backup, it creates more folders in the bucket everytime I initiate backup job.Questions:Does Commvault even leverage versioning feature of the S3 Compatible Storage? If yes, how ? If no, then is it safe to say we can keep it disabled with S3 overwrite enabled? How are more folders getting created when I disable deduplication and taking multiple FULL backups of the same VM (no modification to the file system or anything)? Does Commvault overwrite the existing backup chunk folders on the namespace if a backup is taken twice?

Retroactively apply a content filter to a subclient

I think the answer’s probably no, but I feel like I need to ask this anyway:We recently discovered that a content filter was missed on one subclient while configuring the Commvault agent on a database server, which caused the file system agent to back up an extra ~1.5TB of non-deduped data nightly for several months. New nightly backups shrank considerably after we caught the oversight and set the appropriate filter, but not before Commvault wrote around 120TB of redundant Oracle database backups to disk that won’t begin to age out until sometime next year.I know we can go in and manually expire those jobs to immediately free up space on our long term storage, but is there a way to apply the content filter to that subclient retroactively so that we can expire the just the 120TB or so that should have been excluded from the start, while keeping everything else?

Backup storage sizing

Hi Vaulters, Hope everyone is doing well.We have a new commvault platform that will be installed, and we’ve been asked by our storage team what are the LUNs size that are needed for backed up data. In order for them to create and map them to our MediaAgents. So, it’s a sizing question. Are there any recommendations per Commvault or utility that can be used to help us decide what’s the best storage configuration will fit our needs ? Knowing that our platform will back up multiple workloads : VMs, FileSystems, DBs (SAP HANA), Mailboxes (Exchange), Active Directory ...etc. Any recommendation from you guys would be much appreciated.RegardS.

Replace 'global administrator' account in Commvault Plan configuration for exchange online, onedrive, teamss

Hello Team. I have CV data protection configured for Exchange Online, OneDrive and Teams. It’s been running successfully for some time. The customer wants azure ‘global administrator’ account to be substituted in the CV configuration for a different account (with less capabilities). CV documentation states that after the initial configuration ‘global administrator’ can be substituted but it does not specify with what account (and type) it can be substituted with. Thanks!

Sharepoint Backup Failed not enough space on the disk

Some of our sites are failing during backup with the following errors “http://oursite/whatever FAILED There is not enough space on the disk.” I am not sure what disk they are talking about that is out of space. I checked the server our sharepoint sits on and it seems like we have more than enough space on the Disk. Anyone seen this issue before? I wanted to ask here before i opened up a ticket. Also our Sharepoint is inhouse we are not on 365 yet. Thanks for any pointers.

O365 mail backup distribution

Hello,we have configured O365 mailbackups to one of our virtual machine disks which would be almost full in few weeks from now.We don’t want to shorten retention period (it’s 1 year and its our policy to keep it this long) so we would like to ask if its possible to somehow distribute/divide backups to separate disks? Or easiest way would be to attach new disk and reconfigure backup location (backup destination in plan settings)?

Difference between VM Backup and IntelliSnap backup in Azure

Hi All, As far as I know, Intellisnap backup is the one of the great option in physical environments. It brings, lot of benefits and improve backup performance.As per my understanding, during the VM Backup, the software snapshot taken by hypervisor, whereas in Intellisnap, hardware snapshot taken by storage and mounted in the VSA. But, I couldn’t figure out, how the IntelliSnap backup works in Cloud (Azure) and how its beneficial over Azure VSA backup in terms of backup performance.Because, both scenario, its a software snapshot and it suppose to be mounted in the VSA to perform backup copy nothing but streaming backup. Can anyone provide more information and also share if you know any whitepaper. Thanks,Manikandan

Kick off a VM backup at various non-scheduled times

We have a scenario where the following occurs, managed by a popular scheduling application on a server somewhere1 - Scheduling app logs in to the application server (VM) active node and stops <application_service>2 - Scheduling app kicks off maintenance tasks take place on the Active Node with the application stopped3 - Scheduling app runs PS Script to tell Commvault via our CV “API Server” home brew with Web Console and other components installed to take VM backup of the app Active node with services stopped4 - once backup done, sends result back to PS script and if 0 (success) then the script restarts the application service on the active nodeProblem - This is all unnecessarily complicated by the presence of the ‘homebrew CV API server’ which was built and has no docs.I need a better, aka simpler, way. If the VM subclient cold run pre-post scripts, perfect, but it cannot. Any suggestions please? With details. Thanks

Commvault Azure Immutability

We want to have Azure Blob containers Immutable feature turned ON.Primary - Incremental - 30Days - AzureBlobContainer1Monthly Full backup Extended retention - 365Days - AzureBlobContainer1With Commvault Deduplication.Commvault DDB resides on the Media Agent.How so we handle DDB and the extended retention of INCR and Full on the Container1? Will the data on the container1 expire post INCR has reached its retention for 30Days? Currently we are not sealing our DDB. Do we need to seal the DDB when using Azure Immutable storage? Can we have one Azure Immutable blob and inside them have multiple folders with multiple retention? How does Commvault Retention linked with Azure blob Immutable - Access Policy - Retention Interval? What if Azure Retention Interval on AzureBlobcontainer1 is set for 30Days and My Commvault retention is for 365Days. what happens to the same data on 31st day?

Commvault SQL TDE Configuration on Standy node problems.

Following the rather vague process at Enabling Transparent Data Encryption (TDE) on an Existing CommServe LiveSync Setup (commvault.com) for enabling TDE on a LiveSync configuration.Using the process here How to configure Transparent Data Encryption (TDE) in SQL Server (sqlshack.com) on the Primary CommServe it’s a relatively simple task to generate a Master Password, Cert, Encryption key and apply it on all Commvault databases AFTER turning off LiveSync.Copy the Cert to the secondary CommServe, and using same process after recreating the cert in SQL and Encryption keys apply encryption to “some” of the CommVault databases. However 4 Databases including the CommServ database are in the “Restoring” state and encryption cannot be applied to them. I believe they are in the "Restoring" state due to the log shipping configuration?Only way to do so was run the RESTORE DATABASE [CommServ] WITH RECOVERY to change the state of the Database and then apply the encryption settings. Problem is that

DDB Q&I performance critical - 5,000 - 9,000 ms

Hello Commvault,I try to find a workaround in order to reduce a DDB Q&I times.The DDB is currently 238 TB, based in Shared partitions (Azure Blob Storage).Average Q&I times was 9,000ms (in Premium SSD (P15) in Azure VM, single Drive. After split “DDB paths” (to separate Disks) and add another 2 X SSD (for DDB partitions), currently average Q&I times was reduced to 5,200ms. Is there any way to succeed better performance?Maybe to Seal the DDB ?
