CV11.28 AWS Combined Storage Tier Recall questions

hi @Patrick Dijkgraaf,The recall mode uses standard by default. If you manually execute it you can override it to bulk or expedited if supported on your storage class:Retrieval option: The recall mode that must be used to recall data. Default is set to 0, which is Standard mode. Valid values are:0 - Standard1 - Expedited2 - Bulk The workflow does not seem to be looping or waiting at “Checking Recall Success” - this activity checks if the recall was successful from the output of the previous activity, e.g the previous activity’s output is piped into this activity. So there is no wait or inherent delay that I can see - this is actually how long it took in this instance.

AWS - Couchbase Backup with Commvault 11.28.36

Hi @ChuckC,Yes Commvault uses the builtin command line utility cbbackupmgr to do a ‘dump and sweep’ backup, as there is no native streaming API. So the Couchbase data will be output to a temporary location and then backed up. The location could be a local disk or shared storage like NFS, and I also believe its possible to use S3 as a temporary location as well. I’ll need to check further on licensing …

VMware SRM, DC role-swap and CBT

Echoing much about what Peter said, Let me break this down and you confirm if what I am saying is correct.Using SRM, you will periodically failover VMs between datacenters You want Commvault to seamlessly follow and backup the VM where it resides, and follow it when it failsover Need CBT to be preserved so that backup window is not impacted upon failoverIts been a long time since I’ve worked with SRM, but I have not seen this successfully done in the past, because SRM could not preserve the UUID from vCenter which is what we use to identify VMs globally and uniquely. That being said, you mentioned that there is a UUID preservation mechanism that SRM has  now - I dont know when that came in, but if that is the case and the UUID is truly preserved then I would imagine this would work OK, but you’d have to test it out on your own. Here is what I would do to test this:Build a test VM, record its UUID, configure it in SRM and do a failover - see if it is preserved, and the original VM has i

Backup export on tape

You can do a catalog and merge to bring data back in from a tape where data has aged or you deleted the client/storage policy etc. However, I’d highly recommend just leaving those objects there and hiding them rather than removing them and restoring them later.https://documentation.commvault.com/2023e/expert/recovering_aged_data_getting_started.html

Can I add a suffix to files when restoring in the webconsole?

Hey @Kimmo_SSB,That option is not in Command Center - not sure if it is planned to be added, I’ll see if I can find out. Best alternative is to create a new folder under the original destination called ‘restored’ or something similar and place it there.

Single Item Restore Performance

​ Hi @Fusi,Missing some context here to provide a solid answer, but in a lot of cases, individual items or granular recoveries are single stream restores. Quite often better performance is gained with multiple streams, not only when reading data, but when writing data to the application as well.​

VMware IntelliSnap Primary Snap backup fails

Hi @Stefano Villa,This one is tough because the command we are using to retrieve the storage information from vCenter/ESXi is failing, so there is nothing we can do. In 90% of previous cases this issue is solved by rescanning the cluster, refreshing the storage adapter or rebooting the ESXi host to bring stability back to the API responses.In one case I found a customer said they resolved it by making new subclients - which seems odd but maybe worth a try.Another option may be to restart the ESXi management agents, which can be done without rebooting the host: https://kb.vmware.com/s/article/1003490 For further troubleshooting, you can also query the storage system manually using esxcli:https://kb.vmware.com/s/article/1014953 when this issue is happening.If this fails you have a good case to open a support ticket with VMware to check why its failing.

Hi @Nikos.Kyrm    You can use cool storage for a secondary copy, but not for a primary copy:   https://documentation.commvault.com/2023e/essential/use_express_configuration_option_in_office_365_guided_setup_for_exchange_online.html     I think this limitation only applies to Metallic Recovery Reserve / Air Gap protect rather than bringing your own storage.

Restore an EC2 instance in AWS

Yes but it depends on your restore methodUse auto recovery / replication which is built for this exact scenario and the RTO is possible Use IntelliSnap and restore from snapshot should also be possible Traditional restore from S3 library is possible although likely the slowest method out of the 3. Then, there are 3 different restore methods (EBS direct, HotAdd or Import/Export). The latter being really slow. EBS Direct / HotAdd may be able to achieve the performance you need depending on your architectureRead up on the restore methods and check out the architect guide for more infohttps://documentation.commvault.com/2023e/essential/restoring_full_amazon_ec2_instance_out_of_place.htmlhttps://documentation.commvault.com/2023e/expert/restores_02.html Consider there is likely a cost / performance trade off for many of these options.

Commvault Role for Multi Person Authorization

Hey @flokaiser,I’m so glad you asked as I’ve been working on this a little bit recently. I’d actually love to work with you for feedback (and assistance) as you work through implementing this. I’ll hit you up over DM.Appovers are controlled by a specified group of users - not the permissions or capabilities of the group, only the membership.By default the workflows will consider anyone part of the master group to be an approver. However, after you install/deploy the workflow, you can access the workflow properties to alter which group, or even which individual users are considered to be approvers. In the same place you can also set the minimum number of approvers as well.

Broadcom ends VMware perpetual software licenses

More important for me is how CV will react. is it planned to support Proxmox for example?    VMware have amazing product set, tremendous brand value and single-handedly created an entire industry segment.Luckily, Commvault supports way more hypervisors than any other product I am aware of, including the first to market with AHV support back in 2016 which seems to be the front-runner in terms of product parity for the Enterprise.That being said Proxmox seems to be a hit with the home lab community, but I am not personally convinced organizations have widely adopted it above other distributions that leverage KVM, like oVirt or RHV, but this might just be the disruption the puts Proxmox in the limelight or at least rapidly accelerates its adoption. Or, VMware will prevail given its market and product strength and there will be no fundamental shift.

What is "Network" for a Client which is its own MA?

Hi @Sheree Grier,So this still is reporting on a true network statistic, with the transfer between the agent (database in your example) and the Media Agent. Commvault processes will transfer data over the loopback adapter on the same machine (the same adapter responsible for 127.0.0.1). Depending on which OS you are running, the performance can vary wildly. We have seen some irregularities with some operating systems and patch levels.There is one thing you can try to see if it improves performance. You can switch from using the loopback to using shared memory transfer instead. Its pretty easy to do - but I do not recommend this if this Media Agents is processing a lot of jobs, as the number of parallel operations will also be limited (a separate setting on the MA). Follow the instructions here and ensure the checkbox is de-selected to disable the use of the loopback adapter. You don't need to restart services, just pause/resume or restart the job to after changing the checkbox either w

Does Commvault use ‘versionID’ header in DELETE operations?

Hi Jass,I am reading between the lines here - but Commvault does not work with bucket versioning. This is an excerpt from our AWS Cloud architecture guide: In that case my assumption is we probably send non-versioned delete requests.There is an older thread here where this was discussed in a bit more detail:

Best way to backup a directory with (only) image files. Possibly TB's of image files

I think you are right that there will be little savings, if any if the images are truly unique and the user described how the data will be used accurately. If there are duplicates then obviously there will be some savings, but perhaps not enough to justify using up fast disk storage performance to host a DDB. Keep in mind the saving between full backups as well - even if the data is unique itself, between backup jobs (versions) they could be almost identical.That being said, 500 GB right now is not a big deal, so maybe you can run some tests over a few weeks and see what type of ratio you are getting between full backups and monitor the ‘read world’ profile of this data. A lot of this hinges on your retention as well. If you have shorter retention, its probably not worth de-duplicating. If longer, then it may absolutely be worth it to get saving between full jobs.Never versions of Commvault have a feature call horizontal DDB scaling, which means if performance starts to suffer, it will

Dedicated Interface Paring (DIP) for VMware backup, and HyperScaleX as target

@Damian Andre  hello what i meant was browsing the vcenter cleint content to add vm,s   not live browse. so basically commserv and vsa need to have access to vcenter and hosts. Only a single VSA needs access to vCenter to perform discovery / browse for content, and that does not need to be the CommServe. There is a setting to configure VSA / proxy / access nodes on the properties of the virtualization client and also at the subclient level - so you may want to check both are correct here.

Run incremental backup before Synthetic Full - benefits.

Personally, I’d definitely run an incremental before every time. Hypothetically speaking depending on your retention settings, as time goes on and your incremental jobs age out, you may lose the visibility of what the synthetic full actually contained. Imagine restoring your Sunday data only to find its up to date as of Friday, since that is the last time an incremental ran, but you can’t see those incremental jobs because they are old.

Dedicated Interface Paring (DIP) for VMware backup, and HyperScaleX as target

but when i removed commserv and added hyperscal x as access node, i was not able to browser any of the vm.  I don’t think its a comms problem here - you need a windows VSA to be able to perform the browse operation of windows guests. So its likely failing to mount the file system to browse the VM. You can try browse a linux VM and see if it works to confirm. For browse and restore operations, use a Linux access node and MediaAgent to browse Linux guests, and a Windows access node and MediaAgent to browse Windows guests.Source
