DDB space reclamation feature results

The Quick DDB Verification Job identifies all the files that can be defragmented and logs the details in the DDBMntPathInfo.log, but Is there a Commvault log where I can find the space reclaimed after a DDB space reclaim job is done?

3DFS Share for a NDMP Intellisnap Backup Copy

I have some "NAS/network shares" with different backup types (network share CIFS/NFS or NDMP).The backup copies for shares using FileSystem Agent via "Network Share" can use 3DFS and those using NDMP once cannot use 3DFS. Unfortunately, I have a requirement/need to be able to use 3DFS. How can I share backups of NDMP NAS shares via 3DFS? Am I missing something, is there a setting or do I have to live with it?

Mount path to Mount path Data Migration

I need to check if there is any option to move the data from one mount path to another mount path in the same library. I need this to be done for mitigating over commit issue at back end storage. I am having 3-4 mount paths in which only one job is there , i want to move that one job to any other MP within the library and get that deleted so that over commit issue will get solved.  Current Version: V11 SP26.23Backend Storage : Netapp

Implementing cloud combined storage tiers

We’re setting up a POC to use a cloud MA to copy longer term retention copies (1 and 7 year) from Azure cool blob storage to archive, and would like to use combined tier storage for the storage in the library where the long term copies will be kept.  This being our first time configuring combined tier, I tried to find documentation describing how to configure it, but as of yet have not been able to.  One question I’m hoping to answer is do we need to (or can we) pre-create the cool and archive storage accounts that will be used when configuring the new library, or is there some other way this gets done?

Refresh arrays with intellisnap

Hi team, I need help designing a Commvault configuration for storage infrastructure renovation. We have a customer who has an old netapp storage with two arrays with snapvault and snapmirror between them managed by Commvault with OCUM and all clients using Intellisnap. The customer will refresh the storage arrays by moving SVMs to new arrays, I am not really sure if just moving the SVM will be completely transparent for Comvault transparent for Commvault or will it be necessary to configure the new arrays, the SVMs, and create the replicas from scratch again. Thank you.

Secondary copy schedule

Hello,Can I change the Secondary Copy schedule from the webconsole?I haven’t used the webconsole very much but with deploying a new commcell I’d thought I’d look into it. I do know how to handle it from the javaconsole. Documentation didn’t give me much as it is a mix odfjavaconsole and webconsole content (confusing)Best regards Henrik

System Created Jobs execution

Hi guys, We are implementing an Air Gapped DR site, so the DR site only receives an offline copy from the main one through aux copies.For aux copies, we only disabled their schedule from the “System Created Autocopy Schedule” and created a new specific schedule which start the aux copies to the DR site after the blackout window. Since the DR MAs and Library are only accessible during the Air Gap window, I was wondering if rescheduling the remaining system created jobs (DDB Backup, DDB Verification, DDB Space Reclamation, Data Aging) to the Air Gap period doesn’t cause any issue when running at the same time with the Aux Copies (Our Aux Copies use Deduplication). I know that, when running the DDB Backup jobs, this may cause issues with Aux Copies as of the screenshot below : https://documentation.commvault.com/11.24/expert/12504_deduplication_database_backup.html So my question is, is it possible to launch all the previously listed system jobs at the same time with Aux Copies without an

Sealing a DDB - what happens to the old DDB?

Hi Commvault-people. I have a large partitioned DDB which has been writing to a Cloud-based library, and has been for some time. The DDB partitions are roughly 2 TB’s in size. As is recommended when you have been writing to Cloud libraries, it should at some point be sealed, and I would like to go ahead. We are also on the cusp of the maximum threshold for Q&I times. However, I need to make sure I have enough space for my DDB on the current volumes. So the question is, what happens to the old DDB? I am assuming that it will remain at 2 TB’s in size until there is a corresponding reference for the blocks in the new DDB, or the blocks eventually age and are therefore not required. Maybe that will take months. Quite probably. Whilst it ages out old blocks, will the old DDB reduce in size? But what can I expect from the new DDB? If I only have a 3 TB volume, and 2TB is taken up by the old DDB then I really only have 1 TB available. if anyone has recently been through this scenario, it

Why seal Cloud based DDBs?

WORM copies retention

Hi guys, In order to configure hardware WORM beside commvault’s WORM, we found this note "If you have multiple storage policies/copies created using the cloud storage pool, make sure to set the same number of days as retention in all the copies." under the link below :https://documentation.commvault.com/11.24/expert/9251_configuring_worm_storage_mode_on_cloud_storage.html Does that mean that all the secondary copies that have to be stored on the WORM storage have to have the same retention ? It got me a little confused. Since in our case, from each Storage Policy we will create a new copy that will be saved to the WORM Storage, do we have to assign the same retention to all the newly created copies ? Thanks in advance

Read Performance on NetApp iSCSI Disk Library

Is anyone using NetApp for CommVault disk library, we just replaced the HP MSA2050 with NetApp FAS2720, this is 72 SATA 14.5 disk enclosure. The write performance is great but read is supper slow. The Aux copy is very slow for SQL DB backup and Exchange. I run Validate Storage on 1 path, all backup and aux was disabled, that is the max read of 31 MB/Sec

Duplication of tapes for onsite & offsite backup

We currently have 527 tapes in our library (physically in the tape library as well as “offsite”).  I would like to duplicate all of these tapes to store offsite, as well as create duplicates of any new tape moving forward.I would like to have every tape available in two different physical storage locations.  This way if one of those locations is lost to a natural disaster we don’t lose our backups.How would I go about achieving this?Thanks in advance for any help you can provide!

Backup job with no compression

Hi,we installed a new dedupe appliance as a new library. we are now configure a new SP with no compression and no encryption (commvault dedupe in on).we need to replicate the data using aux copy to the DR site with a straight disk library (JBOD).my question - if we backup with no compression ‘ will aux copy also transfers uncompressed data to the DR site? because in this case , we’ll be run out of capacity in the DR library.thanks.

Library not recognising tapes since new CommCell Server and DR database restore

Hello Fellow CV Community I have an issue with our USA CommCell.  We had to build a new 2019 VM CommCell Server due to the fact we were running on 2012R2 and we could not upgrade our Service Pack to 24 until we went past that OS.  Since upgrading and doing a DR restore, any new tapes we put in our library come back with the following when verifying the media:“Media in library [HP MSL 4048 Tape Library], slot [slot42] does not have a valid media label that is not written to by this product.”We thought this was just an issue with tapes that were in the library, when we did the upgrade and saw this an oversight.  However this is happening after we took all those tapes out, rebooted the library and added brand new tapes in to the library.Our infinite backups are at risk until we get this resolved.  Any help as always would be greatly appreciated. TonyQ

Aux copy properties showing Media Not copied "Stream No./Sequence" column containing "stream" 0/1?

I have some Aux copies that have this, for example:The Aux copy is configured to use 8 streams via “Combine source data streams = 8”.  Multiplexing is not enabled.  When it runs (in properties → Streams tab)  it has 8 “Destination Streams” running (“Number of readers in use = 8 ). BUT when I look at properties → “Media not Copied” tab, it shows 9 streams in the "Stream No./Sequence" column, where it is:what's “0/1” → Stream Number 0? but if so then there’s 9 streams to copy?  I wanted to make sure something was not misconfigured somewhere and Stream No 0 wasn’t some default to handle an oddity/overflow of data or something strange.  I was under the impression the streams were to be combined to 8 (all data broken up into 8 chunks to be streamed/read/copied) … yet the UI is telling me I have 8 streams “to copy” and another one named 0, though it actually only runs 8 streams/readers. For reference, here's the active streams of the same job showing 8 readers/streams
