Storage and Deduplication

Dear community,I have an issue after migration from Windows 11.36.49 to Linux 11.36.49 , the Vault Tracker reports is currently empty :No tape from the location appear in the “Due backup for reuse” report while 7 tapes get a status “Now” on the “Due back for reuse on” field from list of media : On the vault tracking report with broader criteria, I get the following message : Please, what do I have to checkBest regards,Gilles

Hi guys!I need your help.I am trying to use AirGap Workflow to set proxy cennection between MediaAgent ‘cvmakrk01’ and CommCell Infrastructure.I have created following computer groups.  Then I have created the following Networktopology for AirGap workflow. My goal is to push Commvault to use ‘cvproxy’ client to set tje network connnection between MediaAgent ‘cvmakrk01’ and Commvault infrastructure anf the use AirGap workflow to turn on ‘cvproxy’ only for the time of AuxCopy jobs.However, I can see, than even if the ‘cvproxy’ is powered off, the Check Readiness still shows me that ‘cvmakrk01’ is ready.

Good afternoon everyone.I have a question about Commvault's cloud libraries. A client would like to use Wasabi Object Storage, but I couldn't find any specific requirements in the documentation for using Wasabi as a library. Is there any documentation on this?

Hi,Here is my situation :For a specific server plan, a synthetic full is missing for July and August. We have extended retention for this server plan on AirGap so that one full by month is kept for a year. I have Synthetic full with all VMs of the subclient for : May, June and September but I don't have Synthetic full for : July and August. The difference between these months is that we added a virtual machine in July and August. At the time of addition, there are full backups to back up only the virtual machine we just added. Here is the answer of the support :When a new VM is added to a subclient, Commvault automatically will take a full backup for that VM during the next scheduled backup. If, during July and August, the synthetic full backup for the subclient was not triggered or completed, it may be because the schedule detected that a full backup was required for the newly added VMs. As a

Hi Team,Im wondering if anyone has any success, or otherwise using S3 standard as a Primary copy.We will be deduplicating.That would not be my preferred option, as I always prefer faster disk than a Cloud-library offering, but the question is being asked.We do have some fairly large databases (a few TB’s) and I’m wondering how the throughput of say a 5TB DB would hold up in a restore situation.It would be good to hear people’s feedback on this subject.Thanks

I have 2 media agents connected to tape library with 8 drives… and they both host a Plan and I can’t seem to have the aux copies to tape to use more than one drive. Each plan has 30 Streams and the aux copies use the primary copy as the source copyEach also have an aux copy going to the other one (01 to 02 and 02 to 01) . In the media tab, I’ve combined source data streams to 2 and I did not multiplex..Should I use the second copy as the source for the tape copy then?I find this whole part a bit confusingthxG

If Compliance Lock is enabled on a Storage Policy, Does it affect anything else in the storage pool?

Hi, I am looking for a complete list of resources from each cloud provider that Commvault is able to protect.  It’s currently being used for my VMs, some DBs and AD.  

Hi,Please, could you help me with the following question:Currently our customer is using Commvault’s deduplication feature for every copy (primary, secondary).They want to start using hardware deduplication (from their backup storage appliance).Since secondary copies are written to a secondary site, we were wondering if it is possible to disable deduplication just for the primary copy (which would use HW dedup) and enable it only for the secondary one, in order to avoid high network usage between sites. Thanks in advance!

Hi.I’m interested to know if Commvault (11.40) can work with Veritas Access Appliance as Object Storage via S3? I can’t find any documentation on it, but in theory if it’s standards based S3 it ought to be compatible...Thanks.

NetApp is currently selling the successor to the ASA (SAN Only), the ASAr2, at an attractive price. Basically, it is a system from the ONTAP family, like the FAS or AFF systems. Unfortunately, the API has changed considerably, and Commvault does not yet support the ASAr2 API. I’ve heard that integration is being worked on. Is there a timeline for this?We have a few projects where Commvault (new customer) and NetApp would be a good combination.

Hi,Is there any statistic, maybe in logs, what amount of data is send from storage to media agent during restore? In backup we have “Data transferred on network” but what about restore?I mean - let’s say I’m restoring something from Disk Library or Azure - data in library is deduplicated and compressed. I know that dedupliaction doesn’t matter here, but what about comporession? I believe media agent get compressed data from storage, uncompress it and then send to the client? So size of application will be not the same as the data size taken from storage? How to check it? Regards

My customer just testing Storage accelerator in his environment and has some questions.Scenario 11.36 : Client installed with file agent. SA in place and does its work for weeks. Now the connection to the S3 library failed for some reason.We observed that backups still running but without SA (fall back) over a MA.We also observed that backups do not come automatically back to SA if network connection to S3 lib is repaired.We found some keys in registry which may steer the behavior, but we do not completely understand how the software decided to use the Storage accelerator feature or not.  If we have no connection to cloudlib the two keys are created.The StorageacceleratorAutodisabledUntil key seems to renew all 24 hoursThe StorageacceleratorConsecutiveFailureCount seems to be increased after timestamp StorageacceleratorAutodisabledUntil was reached if “S3 network connection” is down.Max value is 8 .

Is anyone else getting this error message every time their SynFulls run?  11.36.46 I want to say this stuff started happening when we moved from Server 2012 to 2022, but I don’t think that’s my problem.  Windows Server 2022 - CS, MAs, VSA Proxies Every time the SynFulls run, most of them sit there in a Waiting status, yet there is always a single stream that shows Active (some over 24 hours) and always throw this error message, which was supposedly fixed a few MRs ago:Error Code: [19:1926] Description: Some jobs were skipped due to read errors. Will retry after some time.

Hi everyone,I have several commcells. On one of them there are “No data available” on the Comcells, Agents, and Client Groups tiles. All other tiles seems ok. Anybody know why and how to fix it?Also, on my other comcells there seem to be no data from january to july for the same three tiles. I guess there is no way to generate the missing data again, but do anybody know if it is a known bug? RegardsGunnar

 Hi Team, We are getting the below error very frequently while running aux jobs. It tells that all device streams exhausted and job will be in pending state until streams become available. Please advise me how to allocate devices streams to avoid this issue.  I have increased Parallel data transfer streams on the Media agent level and Device streams on the Storage policy settings- it does not seems to be helping. Please advise me how to define stream values and what are the things we should consider when increasing or decreasing the streams. How it works?  

Hi Team,After upgrading to Commvault Platform Release 11.40.13, we observed an issue in the Backup Job Summary Report. The report now shows an additional status – “Completed without Backup.”On review, most of the jobs under this status belong to SQL servers with databases configured in Simple Recovery Model, where TLOG backups are skipped. Although the jobs complete successfully, they are being flagged under this new status, which is impacting the SLA completion percentage in reporting.We would like your guidance on the best approach to handle this: Exclude “Completed without Backup” jobs from the Backup Job Summary report so they don’t affect SLA metrics. Alternatively, create separate schedules for databases configured with Simple Recovery Model (without TLOG backups). Kindly suggest which appr

Hello guys!we have 5 XL Linux Media agents, and all of them have 2 DDB Partitions in the size of 5.9 TB. both of the DDB partitions are configured in RAID 1  when trying to configure storage pool from these media agents, we only can configure up to 6 DDB Partitons, and we need all 10 partitions to be available within the storage pool  is there any chance of it?
