Possible to reset media refresh tag on tapes?

Hi,Is there a way to “reset” the ‘Picked for Refresh / Prevented’ status of media? Some media was marked as prevented, and then the auto refresh criteria was changed after. How do I see which of these “Prevented” media should be auto picked now, I can only flip the manually “prevented” media back to manually “picked” Thanks.

On Prem Aux copy to S3?

We are looking into adding an additional layer of offsite backup storage. Amazon S3. The current idea would be add a 3rd copy to an existing storage policy. This copy would reflect the AWS S3 library. Can I Aux copy on premise backup data using physical on premise media agents directly to S3 Any suggestions would be appreciated. Thank you

Commvault Official Deduplication Limits

I think there are several deduplication-related subjects that require thorough documentation by Commvault. 1.) There is a long-standing recommendation to limit deduplication database disks to TWO PER MEDIA AGENT.’ I was able to track this recommendation as far back as Simpana 9.0, but I’m not sure if it pre-dates that. This limit feels rather arbitrary, and it doesn’t take into account the performance capabilities of the host platform, or advances in computing kit since the original recommendation was made. I can’t find any references showing WHY such a limit should exist.In my case, I have three Deduplication disks on my media agents (all NVMe SSD), and that runs with zero issues. The Media Agents are spec’d over the recommended Extra Large spec, and they don’t even sweat. I would like to issue a call to Commvault to really explain why this limitation is in place. The Deduplication Building Block section of the documentation would be an ideal place for this information. Th

new global deduplication database separation

Hi All,i have created some new GDSP and i notice that DDB are separate in 3 ID by type of backup (Files, Databases and VM)i have created this commserve (CS2) in FR20.11.22, (currently the commserve is in FR20.11.55).i have another commserve CS1 in the same version 11.20.55 but created in SP16. on this CS1 when i create a new GDSP there is only one ID for the DDB.Why i can’t create a DDB like in the CS2 ?How can i have the same type of DDB on all my Commserve ? Do they need to run a converison script ? or a patch ?Kind regards,Christophe

DDB Verification Schedule Policy

Hi there! There is a System Created DDB Verification schedule policy (Data Verification). In our case it starts everyday at 6AM. Is it possible to decrease the frequency of the schedule to e.g. once a week without any risk?What is the optimum value of the System Created DDB Verification schedule policy? I am asking because there is a quit big amount of data to be proceess during this task, which can reduce the performance of other tasks.

WHAT HAPPEN IF AUXCOPY HAS BEEN COPY TO TAPE

Goodmorning family pls am kind of new to commvault, Now my question is what happen once AUXCopy has been copy to tape will data on media server backup still remain?and if it remain then can i manually delete those data on it? because most of the mounth path luns has been fill up waiting for ageing to effect and the rate by which our data increase is too fast because is a big environment. i check our VM retention policy is set to 30day am thinking if it less risky to manually delete some data off from this disknote we have 5 HQ media server with 80TB each with 10TB each LUNs 2 DR media servers also.

Using imutable storage data volume increase

Hello,I’m trying to do some math over effects of changing 2:nd copy to be stored on immutable volumes in azure.I have retention of 365 days, currently no seal of db database but seems recommendation is 180 days. According to the formula in another post, that would give me that I should have 545 days as immutable days on the storage volume.Our baseline is 18TB.Since there is 18TB as baseline and there will be 3 seals of the DDB, does that mean that I will add 3 times 18TB to the volume since no data pruning will happen for 545 days?//Henke

Enable Physical Pruning equivalent in v10?

Hi all,I have a client still running v10 (yes, I know ...their call) and last year new additional storage was configured in their CommCell (2 sites). A new library and mount paths were created in each of the sites and new Primary and DASH copies created with data paths to the new storage in the respective sites.I’m finding that the storage for the Primary copy in their main site is filling up and there is nothing obvious in the forecast report. Is there such a setting in v10 which corresponds with the Enable Physical Pruning in v11? Thanks in advance.JamieK

Aux copy jobs are stuck on 99%

Hi there, have you ever seen in the Job Controller view, that there are some Aux copy jobs on 99% (progress bar) for a couple of days? Moreover, Estimated Completion Time says Not Applicable. However, Application size and Total Data Process number is slightly increasing during the time. And of course, aux copy jobs are in therunning state. My assumption is and it looks like that there are still some jobs needed to be copied from the primary to the secondary policy copy. Is it possible? And is it worth to wait for the job completion or better to kill the job.

Audit Reporting: Confirm data exists in all storage locations

Hey everyone, I’ve got a bit of a puzzler. We have several years of data on prem, and in a 3rd party S3 bucket. We’re looking to reduce the footprint of this on prem and 3rd party S3 bucket somewhat, and are moving the data to AWS and Azure combined storage tier libraries as it’s long term data that we need to keep per SLA, but do not expect to recover from unless a project is resurrected or a legal search request comes in, and as such, we can lower some costs by storing it on the lower cost AWS and Azure offerings.The test Aux copies worked quite well - I can see that both my AWS and Azure libraries have the same number of jobs, and the same total data, but if I am asked by an auditor to show that during this work, for client X, that data was on prem, at the 3rd party S3 site, and at AWS and Azure, before I clear it from on prem and the 3rd party S3, I have no idea how to get a report showing that there are 4 copies of the data. Alternately, an Auditor could say show me for job XXX

Separating a monthly full backup from Weekly full, best practice?

We are using a tape environment for our backups. One of the issues i have with commvaults storage policy is that it doesn't really have a difference on how it does full backups. Our retention cycles are a daily backup (Differentials) of 7 days 1 cycle, weekly full 28 days 1 cycle, and a monthly full with 1095 days +. Currently with how the storage policy is set up it is running to the default, all the data is being dumped to one tape and usually has monthly, daily and weekly data on the same tape. I notice when i pull my monthlies i sometimes will see that the weekly fulls and daily are eating up space that could be used to fill more monthly fulls unto the tape.I was wondering what would be the best practice to separate the monthly full away from the other backup retentions of the storage policy? Would it be something along th3e lines of creating an aux copy in the storage policy and just copy the last weekly full to the aux copy to separate the monthly full from the other data? or is

LTO-8 drive compatibility etc..

The Tape Storage Matrix is getting quite “interesting” over time. I am not sure why there are still references to outdated unsupported OS’s and architectures, but that’s more of an comment than a question. I’m trying to verify whether a drive is on the matrix and not coming up with anything. Under the filter section there’s no windows OS. Hmm. If I search for T50e, Windows 2008R2 is the newest “supported” OS for it? What? Is this to say if I call in a ticket for a newer OS on that autoloader might support tell me “sorry Charlie”? Latest code for that unit is BlueScale12.7.07.03-20180817F, it’s not in the Matrix at all. Not sure how to take this or not. Anyone have a similar situation. Plenty of life left in these units and still fully supported by Spectra. Will LTO-8 work?thanks

Application Size vs Total Data to Process Discrepancy

Hi there! Could you please explain here why there is discrepancy between Application Size and Total Data to Process in the Job Controller view? My assumption is that there are some leftovers from previous backups, that need to be backed up/to be copied. Or is there any other reason?

Import backup from Disk Library

HiBackground: Our backups are stored on a Data Domain and the Data Domain replicates itself to a remote site, additionally we've got daily snapshots on the data domain itself to prevent backup data deletion (these snapshots can only be deleted using the sysadmin account).Because we use Data Domain we are storing our backups without compression or deduplication. But my question can be the same for the following situation:Lets assume I've got a media agent, with a data disk (where the disk library is on) attached to it. the building catches fire and I am only able to unplug the data drive. I loose everything expect for the data drive. If I install a new commcell, can I then import the backups from that data drive somehow?

Balance a DDB

HiA single partition DDB outgrew its SSDThe simple solution was toadd a spare SSD and partition the DDB - to now have two active partitionThis has resulted the second ‘empty’ DDB growing a little, but the original partition has remained almost full (due to some infinite retention clients) Is there any way to ‘re-balance’ the DDB’sI could perform a full reconstruction (from disk, not from a DDB backup) - That's going to take 2-3 days to completeI wondered whether there was a ‘hidden feature’ or a workflow that could dynamically ‘equally balance’ the space used by the DDB - to be equal across both SSDs Many Thanks
