Migrate a Data Path

Hi, we just started to use an object storage to tier out the data after 7 days. We created one bucket and added it to commvault as backup target. Den we changed the config and created another bucket but forget to delete the first one and now commvault is using both buckets to store the data. How can I migrate the already stored data in bucket 2 (data path 1) into bucket 1 (data path 2) ?After I could migrate the data I would like to delete the second data path and then remove the bucket in the Object Storage.RegardsThomas

VTL to VTL migration

I have an old InfiniGuard VTL that is replicated to a new InfiniGuard VTL and I need to decom the old one.  Is there a way, with CommVault down, to uninstall the medium changer and drives and install the new medium changer and have CommVault recognize the new VTL as the old one?  The replicated VTL has all of the same barcodes.

Unable to add network disk storage

We have CV 11 .24.56 and using Dedupe.  We already have this Disk Library setup and were using 60% of the library but now we wanted to add another mount path and use the other 40% because no one ever used the storage space!  I cannot send screenshots so I will try to explain. We have a Primary site (Pri-1) and an Alternate site (Alt-1) and Commvault copies the data to the Pri-1 Disk Library and then we do a Dash Copy of the data to the Alt-1 Disk Library so we have 2 online disk libraries one at each site and the libraries each have their on Folder or Mount Path and we have Global Dedupe policies one setup for the Pri-1 Library and another Global Dedupe setup for Alt-1 Library. (This is how it was setup by installer).   My issue is that when I went to add the extra storage I was able to add the storage as a new Disk Library with a new Mount path successfully.  The libraries show up in Commvault as Alt-2 and Pri-2 under the library.  I then was able to add this second  Primary Data site

Enabling Ransomware Protection on a MediaAgent for disk library

Hi Community , Does Enabling Ransomware Protection on a windows MediaAgent CV feature make my disk library and backup copies immutable ? Do we also need WORM enabled primary or secondary copies even after enabling this CV native feature for full proof ransomware protection ? If yes , what is the use of ransomware protection feature ?Regards, Mohit

Setting up a Proxy Server to Access the Cloud Storage Library

Hi, We are configuring a Cloud Library as the Export Destination for Disaster Recovery (DR) Backups.So whenever we take a DR Backup, the metadata is exported to our Cloud Library.However, the CommServe has no direct access to the Cloud Library, it must connect to the cloud storage through a proxy server as explained below:https://documentation.commvault.com/v11/expert/9171_setting_up_proxy_server_to_access_cloud_storage_library.html I am wondering which port should we use in step “8”, because using random port number doesn’t work.Do you have any idea? Best Regards

OK to kill long running DDBBackup job?

I’m having problems with DDBBackup jobs at my DR site.  I changed the configuration from every 6 hours to once per day but the backup from yesterday is still running and I’m at the 22 hour point.  I’d like to kill this job and let a fresh one start but I understand that the DDBBackup uses snapshots and I’m afraid that if I kill it there won’t be a proper snapshot cleanup.  Is it OK to kill a DDBBackup job that’s been running almost a long time?Ken

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

Copy backup data from tape library to Cloud Library (Cloudian)

We have a storage policy with aux copies that was sending disk backups to a tape library. The library in question that contained all these tapes has been decommissioned. A new library was stood up and all tapes were put into this new tape library. However the aux copy that represents this data belonged to a different media server and physical library. We are trying to figure out how to take the data sent to the AUX copy in the old storage policy and move it to a new Cloudian array that has been configured as a Cloud library.

Aux Copy Schedule

Do aux copies start after the backup copy time retention time was reached. Or do Aux copies start at the same start as the backup copy but just to a different location? I am aware Selective only does Full  and Synchronize does Incremental and Full

Tapes with jobs that have multiple retentions - what happens?

Greetings!I’ve been involved in backups for quite a while, but have mercifully been using drives ~ not tapes.  I’m now having to consider tapes.  We have multiple SLAs, including:A monthly full backup to tape, retention to 62 days, lasts 1 month only A monthly full backup to tape, retention of 365 days - so 12 tape backups  A quarterly full backup to tape, retention of 365 days - so 4 tape backupsThe last full backup of the month goes to tape.  So, I forsee a single tape (or a group of tapes with a mess of… ) consisting of 1 month + 12 month retention times.  Some of these tapes will have jobs that last a year as well as jobs that expired months earlier.  What is everyone’s experience with such a thing?  We have over 750 servers involved here.  CV has but one tape drive currently and an operations group to rotate tapes.   Thank you in advance for any experience you can lend me…  Mike Rucker

Number of Pending Prunable Records

Good afternoon,I wanted to check with the community before generating a case with support, regarding the number of outstanding prunable blocks. On a library, which has started to increase 1TB per day, we have applied a 'run space reclamation' and have recovered 30TB of 65TB it had in size. Although this library has only 6TB in use. It is strange. We are seeing a large number of outstanding prunable blocks but performing the 'run space reclamation' does not remove them.     ​​​​Does anyone know the reason?Thanks

Estimating How Long Tape to Disk Auxcopy will take

I am in the process of moving all our data from tape to a disk library and need to estimate how long this will take. Has anyone come up with a reasonably accurate way of predicting how long Aux copying data for a given copy would take.I have 6 x Tape Drives in a library. This has been used a a target for multiple Auxcopy operations for multiple Storage Policies. Due to tape contention a multiplexed multi stream Auxcopy for a Storage Policy copy could be written to 1 to 4 drives depending on drive availability. I am also interested to know how this works. When the operation began it copied the oldest data first , but as time went on the completed and partially copied data began to appear throughout the timeline. Is there away to make the most recent data copy first? Does an Auxcopy operation begin copying all jobs on a given mounted piece of media, or does it only copy some jobs and will have to mount that tape later.

Both data and archive log use same storage policy At storage policy level I created auxiliary copy with selective copy all fulls. But when I checked the jobs inside this auxiliary copy I can find oracle data full backups only and it is not contain the archive log backup jobs.

Move Backup Data to new New Storage

Hello Every one,Our current storage is almost out of space, so we want to move all of the backup data to a new Storage.we are thinking of the following:- Create new Disk library contains mount paths of the new storage.- Move the mount path from old mount paths to the new mount paths.- Change the storage policy data path to the new mount path.The reason behind we thought of using moving mount path method, because using Aux copy method would require to stop current backup jobs while moving the mount path doesn’t require that.what is your advice about this approach

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 ?
