Automatic backup: Oracle archive logs when disk at log destination doesn't work

Hi,We have a dedicated mountpoint (filesystem) for Oracle archive logs.We use the schedule pattern every 4 hour and extra start of backups when disk at log destination is above 45%As a test I fill that archive directory far above 45%. The automatic arch backup didn't start.Do we miss something?Thanks,Ron

OnePass retention settings and backup chain

For Archived data produced by the OnePass feature in Commvault what determines the retention time in the Storage Policy Copy?There is a “Basic Retention Rule for All Backups” and a Basic Retention Rules for Data / Compliance Archiver Data. If I’m right the Basic Retention for All Backups setting would dictate retention for “backups” that were referenced by subclients to that storage policy and the latter would just reference data that was archived by OnePass and uses the same storage policy copy? So if the “Basic Retention Rules for Data / Compliance Archiver Data” setting is infinite data created by OnePass will never age out? Secondly if the schedule associated with OnePass is configured to do a nightly incremental and never a Full or Synth Full what is the impact of deleting a heap of Incremental Backups in the backup chain? A full was done only the first night this was set up.I was never intended to retain the Archived files indefinitely and as a result 3 years of unwanted non dedu

Move old DDB and Mount Path to new Media Agent to dismantle the old MA

Hello everyone, I have a quick question, I am fairly convinced this is the way to do it, but due to the nature of it, I am unsure and want to make extra sure.A few months ago, we deployed a new media agent in one of our Commcells, to replace the old Media Agent which was going EOL. We would now like to dismantle the old EOL, however, the old DDB on the old MA is still showing referenced jobs (132 of them):  We are now at a point where we can no longer wait for these jobs to naturally age out. Along with support, we have worked out a process to move all data away from the old media agent. This involves moving the mount path still residing on the old media agent to the new one using this process: https://documentation.commvault.com/2023e/expert/156684_moving_mount_path_to_new_location.html as well as moving the old, sealed DDB to a new partition on the new media agent. Then, we would check all jobs in the sealed DDB to make sure they are now referencing a path on the new media agent, and

Description: Error occurred while processing chunk - error Code: [13:138]

Hi all!could you advice me how to troubleshoot following types of error: Error Code: [13:138] Description: Error occurred while processing chunk [xxx] in media [xxx], at the time of error in library [disklib01] and mount path [[xxx] /srv/commvault/disklib01/xxx], for storage policy [XXX] copy [Xxx] MediaAgent [svma1]: Backup Job [xxx]. Unable to setup the copy pipeline. Please check connectivity between Source MA [svma1] and Destination MA [svma1].  At a glance, it seems that it is not possible for CV to process chunk from the (index?)/disk library...However, the issue is connected with storage policy copy, that moves data from the disk library to the tape library (secondary copy). The main problem for us is that it is not possible to copy data to the tapes. Therefore, it may say Unable to setup the copy pipeline. The media agent is one server/device, that communicates with both disk and tape library. Lastly, the files in the related directories dont seem to be corrupted...Any suggesti

Purpose of Air gap Protect

Hi Team, I would like to understand, exactly what the “Air Gap Protection” do?Is it just MRR storage target which can store backup copies, or will it have any core Air gap capabilities like restrict/isolate the access to stored data?

Dear Team, We have around 20 LTO9 tapes available to take backup weekly and monthly secondary copy. Now I need to assign each media to dedicated media group once loaded into the tape library not for manually move.I gone through commvault documents says that we have an options to create Barcode patterns with the media to assign automatically to the particular media pool or media group. My questions, we have Weekly and Monthly media pool and AFK001L9, AFK002L9, AFK003L9, AFK004L9, AFK005L9. I need to assign AFK001L9, AFK002L9 media to Weekly pool and AFK003L9, AFK004L9, AFK005L9 medias to Monthly pool.   Barcode pattern name and Barcode pattern option???? Could you please help to fix the issue.

Moving Tape Drive from one media server to new media server

We have moved a tape drive from one media server to another media server. When configuring the tape drive in the commvault, do we have to deconfigure the old tape drive configuration in the commvault. If so does the assigned tapes on the old media servers loose the data?

SAN Data Server

Hello, I’d like to use a SAN data server to present the several LUNs, coming from SAN storage, to two different MediaAgent.The question is: on SAN data server, have I to use LVM, to create volume group, logical volume and lhe filesystem, to group these LUNs and then share the mount path to the Media Agents?If so, I think there is a filesystem size limit that cannot be exceeded for a single volume and consequently the corresponding mount path configured on the SAN data server and shared to the Media Agents.Another question: could I configure one of the two media agents as a san data server?Thanks and regards

Backing up data again on Linux file server after temp move

The goal on our Linux file server is to replace the current /project1/ directory with new /project1/ directory, all the same data, but the data stored on different back-end storage. All of this data is backed up by Commvault with the Linux File Server Agent but not doing block level backups.However, when doing a test, we discovered that Commvault will back up the data again after its moved back to the new /project1/test/ directory, even though the data is exactly the same (same file sizes, modified dates, etc).I populated a folder on the file server /project1/test and created a Commvault sub-client for only that directory. I ran a manual full backup, which backed up 344MB of data.Then I ran the following commands (as root on the linux file server)rsync -avHxAPS /project1/test/ ~user/temp/Removed /project1/test/ using:rm -fr /project1/test/Synced the data back from /temp/rsync -avHxAPS ~user/temp/ /project1/test/Reinitialize the xfs project quota:xfs_quota -x -c 'project -s test' /proje

Adding new DDB partition

Hello,Planning to add a new partiotion to an exiting DDB. I’ve went through the documention and have a doubt on the below.The addtional 0.5MB of data will be added only to the magnetic disk the holds the DDB or will it be also added to the Disk library mount paths ? “After running the Backup1, you add Partition2 and run Backup2 of the same 1 MB of data. After the second backup, 4 signatures of 128 KB size will be added to Partition2 (even though the same signatures exists in the original store) and for the other 4 signatures only the reference will be added in the original store (as the signatures already exists). The magnetic disk will have 1.5 MB of data (1 MB from the first Backup + 500 KB from Partition2 from Backup2).On running data aging, if Backup1 is aged, then from the first partition the first 4 signatures will be aged and also 500 KB of data will be pruned from the magnetic disk.”https://documentation.commvault.com/2022e/expert/12455_configuring_additional_partitions_for_ded

CV11.28 AWS Combined Storage Tier Recall questions

Hi all, At a customer, we are using Combined Storage Tiers:CV 11.28 AWS Deep Glacier / Standard-Infrequent Access We have a few questions on this:When we do a restore, the Recall workflow kicks in. We see that it initiates the Recall and then waits for 13 hours before checking the Recall Success. Why is it only checking after 13 hours? The data might be available sooner, so it would make sense checking earlier.   Which Recall type is used by default (with CV 11.28), is it Standard or Bulk? Thanks in advance!
