Self-Hosted Q&A

I am working on some performance issues with my backups.Looking at the media agents during the backups, looking a the media/proxy agents I am seeing what I think is high latency on the loopback adaptor.   in the screen shot below you can see in in Windows resource monitor the latency for vsbkp, cvd and other processes are around 30ms.   The loopback adaptor is internal to the server, never touching a ethernet switch or wire, so I would think it should be much lower right?I am wondering what type of latency other folks are seeing on their media agent and or proxy agents during backups?Thank you ahead of time!  

Hi ,  we have aux copy to tapes which is our 3rd copy , and we can see big data app job being copied to it frequently , how can we exclude it 

Hello!Is there a way to create a new server plan and disable the creation of the default snapshot primary copy?I don’t want to go to commcell console and delete the automatically created primary snap copy. I just want my primary copy and tape copy when I create a backup plan.Regards,Pedro

Hello All,I have a question regarding the behavior of an SQL cluster. Scenario:This cluster is made up of 2 VMs with shared disks. There is also a witness client to this cluster. The witness client was rebooted unexpectedly, and so I’m assuming Commvault determined that the cluster was lost, since a backup set and instance were automatically created on one of the client nodes. What brought our attention to this was that we received an alert that this subclient could not be backed up since there was no Storage Policy associated, and permission not configured, which was to be expected.My questions:Is this normal behavior? (I believe that it is?). If so, why would Commvault do this given it can’t be backed up anyway with no storage policy associated, etc...? Is there an option to disable this behavior? Am I correct in saying that by the witness client being rebooted, the system assumed the cluster was lost? Also, this is not the same as a failover, yes? If an actual failover occurs, would

Hey Guys :)Running a restore from a mysql db. Network Test is ok, but throughput is very slow (2-4GB/hr). On the client i can see i high cpu load (80-95%), and the Disk usage is also close to 100%. But my question is (or from the customer): Can someone please explain me how the restore is working? So what is commvault, the Agent, doing step by step? Why does it create such i high load on the cpu and the disk?Thanks :)KR

can we set encryption of for one vm which is part of vsa job in a subclient ,or is it can only be done for client with agent , is there any way to encrypt only a vm wihtout using seprate storate pool or policy 

Hello, Working on a design for a customer that will provide BaaS using Commvault as an MSP.HSX will be used as primary backup target and they want to provide tape copy option to their tenants.They have a Tape library with 12 drives and 240 slots and expecting 6 tenants. Some tenant will self-manage their backup and some will be fully managed by the MSP. I am wondering how we can make a portion of the tape library available to the tenant (storage pool / drive pool ?) and have access only to its set of tapes, drives and slots. Customer does not have license to partition the tape library.TL drives will be connected to the HSX. Thanks for any inputs

I have a linux ubuntu 20.04 server and postgresql is installed on it. File system core, postgresql, file system are installed as software. I can restore full bakcups, but the restore option for incremental ones is passive. What could be the reason for this? 

I am currently troubleshooting an issue when I try to do a full backup restore to another computer. On the first Destination field, I’m able to select the destination server, but on the second destination instance, it’s not populating the same instance. I’ve confirmed the SQL version on both are on the exact same version.  I thought maybe it might be an issue with the product version of the computer being behind. Tried to update, but I’m getting this error. 

Hi,unfortunately, CV has a bug in relation to schedules and CV Support has not yet been able to provide a solution. As there is no end in sight I am currently building a workaround. I am desperately looking for a way to trigger a backup copy via PowerShell (if necessary via REST) or to start the corresponding schedule (is deactivated due to the error). Is there an idea for this? Best regards

Hi teamI am creating and testing some DR procedures including vmware VM restore . I have done some restore performance tests. My commvault is. 11.28. I use hotadd mode (the most efficient transport in my environment because of thin disks). Media agent and vm proxy servers are windows 2019. And restore speed of large single VM seems to be below expectations.It is about 990 GB/hr (275 MB/s, 2,2 gbps).What is a bootleneck ? CPU or MEM is not a limit I believe but I noticed that the data transfer speed between media agent and proxy servers during restoring does not exceed 2.2 gbps (240 MB/s) over a 10 gbps network. It seems to me not enough.I checked outside commvault what can I expect from my hardware. The robocopy network transfer tests of a single relatively large 50 GB file (vmdk) from media agent to proxy and shows a transfer on LAN net of no less than 7 gbps (870 MB/s). ?3 times better than in commvault process ? Is it expected behaviour ? Why ? Can I tune this ? I have tried with nn

Hello,I removed a media agent and I forgot to disable the Ransomware protection before I got rid of  it in commcell.Now I can’t delete the directory since its “readonly”. Unfortunately the directory is on a drive also used for other things so I can’t format it. Since the drive has live data I don’t like to do the disk part thing either.Is there a commvault tool or way for me to get rid of the directory? Best RegardsHenke

We relatively often restore older versions of files to users. In the thick java client you can chose to sett a suffix option on the filename when restoring, to not overwrite existing files, and to make them easy recognizable. We can not find this option in the webconsole. (Command Center). Is this a feature planed to be implemented, or is there a simple solution to ad a suffix?The suffix is very useful when you restore larger amount of files to distinguish them from existing files.  

hi , we have hyperscale with encryption enabled and we are having aux copy to tape with below settings basically each tape should give aroung 40 tb after compression but we are only getting 15 tb  , do we need to disabled the encryption .i can see hardware encryption is enabled in the data path setting for tap e  

can a server be part of 2 companies , i am not using plan , i have only storage policies , i have created a company and tried to move the server to new company created , if 2 company want to manage one server can this be achieved without logging to master account 

Hi community, as we are able to change the language of the commcell console with the following two ‘options’:-Duser.language-Duser.countryIs it possible to define the username with an option like the two before?So that the username is already prefilled if I open the console. Thanks and regardsJulian

What line should I add in the custom report to show extended retention information instead of basic. Here is a part of script I’m running with basic retention string:Return resuls in the given orderSELECT    CASE WHEN S.VMClientId > 0 THEN (SELECT name FROM APP_Client WITH (NOLOCK) WHERE id = S.VMClientId)            ELSE CL.name END AS 'Client',        IDA.name + CASE WHEN S.VMClientId > 0 THEN (' in ' + CL.name) ELSE '' END AS 'Agent',        dbo.FixInstanceName(INS.name, A.appTypeId) AS 'Instance',        BS.name AS 'Backupset',        A.subclientName AS 'Subclient',        C.PolicyName AS 'Storage Policy',        C.CopyName AS 'Copy',        C.StorageType AS 'Storage Type',        CASE WHEN AGE.retentionDays < 0 THEN 'INFINITE' ELSE CAST(AGE.retentionDays AS VARCHAR(10))+ ' day(s);' + CAST(AGE.fullCycles AS VARCHAR(10)) +' Cycle(s)' END AS 'Retention',        CAST(S.dataRead/1024.0/1024.0/1024.0 AS DECIMAL(10,2)) AS 'Application Size (GB)',        CAST(S.dataWritten/1024.0

So we have a VM which is over 22TB in size and cannot be backed up by Commvault.  We’ve implemented a FS backup, but this still takes considreable time and impacts the VM (in use 24/7) heavily.  However, the VMDK has a VMWare live mirror, and we’d like to look at backing that up.  Has anyone done this and have any tips?  Is there a reason it cannot be done?  Lastly, I dont’ see why this wouldn’t be possible, but file/folders can still be extracted, yes? Thank you for any advice! Mike

Hello Commvault Community, We have this situation:On the switches, there are many attempts to connect agents with OS AIX installed to the Commvault infrastructure (the customer reported mainly that connections are being made to an air-gapped).The environment has OneWay Firewall configured (not by topology but on group properties). There are two large groups: the 'Client Servers' group containing all production agents, and the 'Commvault servers' group containing all Commvault infrastructure (except the air-gap server, which does not participate in backups). On these groups a Network Route is configured, on Client Servers the Commvault Servers group is added as RESTRICTED and on the Commvault Servers group the Client Servers group is added as BLOCKED.That is, it is the CV Infrastructure that should maintain a one-way tunnel with the production agents, not the other way around.Unfortunately, for some reason AIX clients (only AIX, because in the logs of several Windows doesn’t show these

An IP address has changed to a linux cluster we are backing up. Do I have to login to one of the cluster nodes to change it? or can i change it through commcell.I am familiar with a change of IP address for a windows cluster not linux Thanks for any replies

Our Commvault users are given access via an AD user group.That AD user group is set to have MFA enabled and therefor all our users make an MFA enabled login. In our domain there is also a user group for MFA excepted users.So now I would like to leave MFA enabled for the users that have commvault access (the commvault user group)But disable MFA for the commvault users that are also in the MFA disabled group. Is this possible?

By accident someone deleted the backup job summary template and lost 75 scheduled reportsDoes anyone know how I can recover them?
