Commvault Q&A, release updates, and best practices
Many of our servers are using SAN volumes, so snapshotting those volumes from Hyper-V or VMware is not possible. We have installed the Windows File System agent on all those servers and are performing backups of the SAN volumes. Our SAN is connected to the hosts over fibre channel. Obviously it would be possible to connect one of our Commvault media agents to the fibre channel, present the volumes to it and then use the media agent to backup those volumes as a proxy. Is that advisable though? I can’t find any documentation on doing this...
Hi, we currently have a customer running HyperScale 1.5 Reference Architecture on SuperMicro hardware. They report that the OS disks are currently configured in RAID0. (details are already requested) They found out the hard way, and would like to change it to RAID1. Can anyone tell me what the (default) config options for the OS disks are? Hardware RAID, Software RAID, RAID1, RAID0? And also, what options would we have if we would like to reconfigure that to RAID1? Would it require a reinstall (I believe we can keep the Storage Pool data)? Or can we manually reconfigure to (software) RAID1, and is that supported? Thanks in advance!
Hi Team, We are about to upgrade our older version of Mongo, which has been causing a few problems with log-files ballooning out. Technically, we are all good with the upgrade process, but I actually don’t know what Mongo does in regards to the Commserve (thats where Mongo is installed). Does anyone know?It would be useful to understand, that in the unlikely event that the upgrade goes pear-shaped, then what functionality or impact to Commserve functionality might we encounter? That would also help in presenting the upgrade change to the customer, who will most likely ask “what is the impact if the upgrade goes wrong”, as they normally do. So if anyone knows, please shout-up! Thanks.
Hi, Yesterday I have updated to 11.24.12. But after installation, I found that it’s now showing my SLA is 28%. Missing SLA includes only the VMs and they are only 4-5 days old and backed up on weekly basis. If I am not wrong SLA period is calculated if there is no backup within 30 days. So is this a bug of this release 11.24.12? Thanks for your answer in advance. Sumit
Hello Community , We have windows 2008 R2 media servers with EMC disk library . Want to migrate to windows 2016 can we directly do SAN level migration and attached the LUNS on Windows 2016 (Not sure will that work ). Looking for better recommendations . We dont have enough space to do Move mount Path .
Hi All, we are trying to backup and very large cifs netaopp filer. We have implemented an NAS proxy for acessing the shares. When we start the job the scan phase broke every 3hours. We tested with an smaller folder / share the scan phase runs in 5 Minuts and the job starts to backup. Is there any additional setting to increase the timeout for the scan pahse ?
Hello ! A couple of days ago I updated the version V12.SP20 to V11.SP24 and installed a hotfix 12. Today I discovered that this hotfix 12 has disappeared from those available for download on the site https://ma.commvault.com/HotfixPacks?fv=11.0&sp=24. There is a problem ?
This is just a question about how we could have better way to rebuild MA. We have a windows based local ma and the data is aux copied to another media agent at a secondary site (different city);The RAID on the local MA was returning errors; so we replaced one of the faulty disk which caused the whole raid configuration to fail. We had to rebuild the whole virtual disk again. Unfortunately since there were only 3-6TB disks; everything OS/DDB/IndexCache/Libraries were in the same Virtual disk and we lost everything. Since we had a copy of the backup data at the secondary location; the quickest way was to rebubuild the MA. The RAID controller was not showing any error; and it was not feasible to send another MA to the site due to lockdown So we rebilt the virutal disk again; installed/upgraded OS to Windows 2019; kept the same hostname/ip configuration; installed Commvault agent and it made the MA online on Commserve. created index cache and DDB added the new mount path in the
Some facts:Version 11.24.7Sharepoint 2016 (on-prem)SP DB backup speeds: 15-25 GB/hr (So not superfast, but atleast it finishes in a reasonable time)SP Documents backup speeds: 1-1.5 GB/hr (So basicly superslow) Some background information:I am a storage guy, who’s recently been put in charge of the backup solution, due to people leaving. While i’ve worked some with other backup solutions before, thats 10+ years ago, so my backup skills are a bit rusty compared to my storage skills, so bear with me if i need things spoon fed :-)Also, the Documents parts of sharepoint have been split up in about 10 different subclients, and this performance issue is affecting all of them.Also, for other backups being run by Commvault, i see very different backup speeds. For instance full backups of some MSSQL servers can provide speeds of 500-3000 GB/hr, so i know the backend of the backup solution can handle a lot higher speeds than what Sharepoint is giving us. Now, if i try to drill down a bit on one
We want to use space on an SSD for a new DDB (horizontal scaling) and the old DDB is not being used. It only has jobs with long term retention as it was used for file archiving(onepass). The onepass jobs are not active anymore. Data only needs to be restored. If Commvault doesnt need the DDB for restores, how can I get rid of the DDB as we dont have any backups running.Sealing could be an option. However BOL mentions:The sealed DDB is automatically deleted only after all the jobs (with their data block signatures stored on the DDB) are aged or deleted and the corresponding volumes are deleted from the disk.So the DDB is required for purposes other than the backup. https://documentation.commvault.com/commvault/v11/article?p=12591.htmFor now we will be moving the partition to a different drive. Any ideas?
Hi All. I have a question regarding restore of data which resides on a offsite private cloud where clients have no access. Setup is:On prem Client network with servers in backup.→ Firewall in between with port open for backup traffic.On prem Backup network with MediaAgents and storage.→ Firewall in between with port open for aux copy data.MediaAgents with offsite private cloud storage containing Aux copies of client data. Clients do not have access to the offsite MediaAgents/copy, so my question is, how do I make a restore of data from the offsite cloud, when the On prem clients and the offsite MediaAgents cannot talk to each other directly? Is it possible to route restore traffic via the on prem MediaAgents acting as a proxy some how? Would the network gateway via outgoing routes be the solution? Any suggestion would be appreciated. Thanks for helping.-Anders
Hello, I am facing an issue where SSO is not working for webconsole :|Setup that I have: 2 commcells, 1 centralised webconsole/metrics host. Web console is attached to master commcell and 2nd commcell is a child commcell attached to webconsole.So, if I am logging into webconsole server itself and to try open webconsole page - it is asking for credentials. I believe it should not due to the fact both commcells have the account in users. I am logging into commcell itself with that account and SSO with no issues.So I was browsing logs on webconsole host and found this: But within the commcel, SSO is enabled in domain controller settings: Maybe someone knows the magic trick to fix this?
HI ThereIHAC that will use exagrid as backup storage with Commvault.Exagrid states that they can add to Commvault deduplication to obtain a higher dedup ratio (up to 20:1 for long term retention data).I couldn’t find any information on Exagrid on BoL and my understanding was that we do not use CV deduplication when using a deduplication storage as primary target.Did anyone implemented CV with Exagrid ? and if so any specifics/culprit or best practices ? ThanksAbdel
Applying New license file in commcell :i have below doubts:Can we apply New comvault license files directly in License page?will it impact active backups?do we need to restart comvault services?i hope nothing will happen, just to make sure i am clear on these part.
Hello All,I am from TSM background and when VTL was introduced in TSM, the scratch tapes were not automatically deleted in VTL. Later, RELABELSCRATCH parameter was introduced and it allows to automatically relabel volumes when they are returned to scratch. I remember that specific settings we have do in Backup Exec and HP data Protector backup software too.→ I want to know whether any similar setting is there in Commvault?More details as per TSM perspective → Virtual Tape Libraries (VTLs) maintain volume space allocation after Tivoli Storage Manager has deleted a volume and returned it to a scratch state. The VTL has no knowledge that the volume was deleted and it keeps the full size of the volume allocate. This can be extremely large depending on the devices being emulated. As a result of multiple volumes that return to scratch, the VTL can maintain their allocation size and run out of storage space. Relabel processing on the Tivoli Storage Manager server are started for libraries (V
We're running Commserver 11.22.9.I have a couple of quick question regarding the Restore-CVSQLDatabase PowerShell module.The command I'm testing is as follows (with parameters provided by caller)...$RestoreObject = Get-CVSQLDatabase –ClientName $SourceClient -InstanceName $SourceInstance -Name $SourceDBName | Restore-CVSQLDatabase -OutofPlace –OverwriteExisting -DestClientName $DestClient -DestInstanceName $DestInstance -DestDatabaseName $DestDBName -DataFilePath $DestDatafilePath -LogFilePath $DestLogFilePath -ForceIs documentation available that covers all available parameters? The doc site does not cover most of the parameters above. Is there a parameter providing for changing the physical datafile name and the physical logfile name? This functionality is available through the CV Command Center.Thanks for any help.
Hi, In case of a ransomware attack (which I hope will never happen), what is the best way to determine what is the last good backup on disk that I have and that is suitable for restore (not encrypted by hackers or contaminated by malware)? Do I need to do a restore in an isolated environment and then run antivirus until I have found the last “good one” ? Or is there a better way? I have heard that malware can already be on servers weeks before the actual attack or whatever. Thanks
Hey Commvault Community. We are an MSP provider running a VMWare Cluster to host our Clients.The environment has an NSX so each client has their own network that is managed. Basically from the documentation and my calls with support we don’t have a a solid solution to doing App-Aware backups. I was wondering if anyone else has gotten a similar setup where they have App-Aware backups working?
