Restores from Azure Cloud Storage

Hello,Our client ask me how restores from Azure cloud storage works when data is located on cool tier and on archive tier on Azure.We have tested the archive tier first. We copied the data to the cloud archive storage, and performed an restore for a database. We selected only one (of many) database which should have size lower then 10GB, but the full job backup size is 8,5TB (Size of application) - Recall archive workflow is working for 3days and completed only 30% - is it recalling all 8,5TB of data from archive storage?And how it would work if we use a cool tier cloud storage - when data is phisically available (online). If we copy a job which have 8TB and we will perform an restore only for one database (~10GB) from this huge backup - will it download all 8TB of data or will only choose this chunks which actually contains the data of this small 10GB database?Thanks in advance for help :)Have a nice day !Regards,Mateusz

DDB reconstruction

Hello,During a DDB reconstruction process, how does it reconstruct the missing data? In our case, it first performed a restore of the last backup which was from sometime early morning. Does it then access the library storage directly to reconstruct the missing data or does it access the Commserve? I’m asking because I’ve been told conflicting information from different Commvault technicians. I just want to make sure that I understand this process clearly. Thank you. Bill

Ransomware Disklibrary

Hi All, we had an internal discussion for new customers what Library is the best way. Often we are running Windows Cluster withs csv volumes or windows filecluster or single servers with san attached storage. In the past there are a lot of problems with the ransomware on CSV an Filecluster. Do you have some more information wich way should be good or better to prevent redirected I/O in cluster and also errors during maintanance ? Also is there any possibility to check if the ransomware protection is working on a CSV / Windows file cluster ? Sure the option is set but did we had an option to test if its working ?

MA hardware refresh and library mounpath sharing

Hi,i have to perform OS refresh of some physical MA ( 2 grid of 4 MA). We will upgrade from Windows Server 2012 to 2019.my purpose is about data availability because our disk libraries are configured with Local LUNs on each MA shared with others via Dataserver-IP option.The problem is when one MA is unavailable for the upgrade, their mount paths were not readable for the others MA. I have search in the documentation and i don’t find any uses cases for doing a MA refresh with shared mount paths. please advice Kind regards,christophe

Auxiliary Copy - restart schedule

Afternoon folksI have an auxiliary copy that backs up to tape - I have deleted all of the existing jobs on the tape media with the hope of starting the backup chain from scratch. However, since deleting the backup jobs, if I go back to the storage policy and right click on the tape auxiliary copy and view “media not copied” it is blank. I was expecting to see all backup jobs for the backup period that I have selected.Is it possible for me to “restart the schedule” so to speak without deleting the auxiliary job? TIA

Secondary Copy from Primary Storage Policy only with daily backups

Hello community ! I try to find a way to send only weekly and monthly backups to a secondary storage (Azure Blob Storage) from a Primary Storage Policy that haves only daily backups (7 days retention).I see from Aux-Copy wizard, that the only way is to create a Selective Copy with only full backup jobs. So, basically to copy only synthetic fulls once a week in my case.But, I cant figure it out, how to copy also monthly jobs!Please for your feedback!Best regards,Nikos

How many drives can we configure to one SAN-Attached tape Library.

Command Center - Adding Tape Library doesn't allow for other scratch pools? Barcode patterns?

Someone on my team wanted to try to add a new Tape Library to the environment using Command Center. I had never done this in Command Center before, so I watched the user go through the steps. We found that it had created the library and the storage pools. But we could not find any way to create barcode patterns or to create another scratch pool from the Command Center.We are an MSP and this is an essential step in being able to use the library.We then tried to create the barcode patterns and other scratch pools from the CommCell Console. We created the entities but then found we could not associate it to the pool/plan.It appears that the option to change the scratch pool is greyed out in this case.Is it expected that you cannot edit the scratch pool when the library/storage policy/plan is created from the Command Center? Or are we missing something here?Furthermore I was expecting a much more user-friendly approach to adding tape to the environment. For example, the user had to s

AuxCopy free space is less than primary

We have 2 Synology 24TB storage libraries, one for the primary and the other at another site for the AuxCopy.The primary has Free Space 15.34TB, Size on Disk 8.59TB, Total Application Size 30.5TB.The AuxCopy has Free Space 3.62TB, Size on Disk 20.33TB, Total Application Size 30.33TB Shouldn’t the AuxCopy be an exact replica of the Primary? Why would it be larger? Thanks for any suggestions.Larry

Auxiliary copy to use and fill same tapes info

Hello,We have bought a new tape library and we want to create some auxiliary copy jobs to run on a weekly basis for 4 storage policies only for the full backup job's(the client schedule is a full once a day/incr every 1 hour)The auxiliary copy jobs must all run during the weekend and occupy not more than 2 tapes( we have tapes with big capacity-16TB) because we have only 8 tapesThe question is, how can we make the copy jobs to write and fill up one tape and after to try and fill up another tape when the first one is full?For example: after the first copy jobs is finished, the second one needs to use the same tape like the first one (if there is still space available of course)and when the tape is full, write on another one and so onBest regards,Stefan

Unusual performance drop detected in pruning

Hey good people at CV!We are getting hourly “Unusual performance drop detected in pruning” event viewer events.I have noticed there was a hotfix here: https://kb.commvault.com/article/77146 , however it seems that 11.28.10 is the currently installed version.At first glance and after reading a few threads here concerning the same issue before posting a repeat topic, I figured it might work itself out.Is there anything else that can be done? Just trying to be proactive.Here is the message to follow, and there seems to be a single Job Record to be Deleted when viewing the DDB Pruning Performance Anomaly Report.Unusual performance drop detected in pruning for following deduplication databases due to increase in (CommServe Job Records to be Deleted)Thanks in advance!

S3 with WORM and extended retention

Situation:primary Backup on site A onto S3 with deduplication, retention of 30 days / 4 cycles, no WORMBackup copy (synchronous) to another site onto S3 with deduplication, retention of 30 days / 4 cycles, extended retention for 365 days (monthly fulls) and 10 years (yearly full), WORM Question:if we enable (object-level) WORM with the Workflow on the Backup Copy storage pool then by default the WORM Lock period is twice the retention, meaning in the above example WORM Lock would be 60 days (2x 30 days). However, how does that affect the extended retention for the monthly / yearly fulls? To what value would the WORM lock have to be set to guarantee that the monthly and yearly fulls are WORM protected for 365 days / 10 years, but all the other backups should follow the “normal” WORM lock of 30 days?If we set the WORM Lock to 10 years (how long the yearly fulls need to be WORM protected) then all backups that get copied would get that 10 year lock, even all the incrementals that get copi
