Aux Copy Job missing ?

Hi, I have a customer with 2 copies :1-Primary dedup on disk with 66 jobs.2-Secondary dedup on disk with 133 jobs He created a copy 3 to replace the secondary but he chose #1 for the source, but there are jobs only in the secondary copy, is there a way to pick the missing jobs by changing the source of copies #3 for source = #2 ? If I change it and run and Aux Copy the missing jobs are not picked ? Or I have to delete the copy #3 and start over !?

Dedup Data Written expands with new DD-engine

Hi, We are setting up a new Windows MA with new DD-Engine and a new DiskLib. The DDB disk has been configured with recommended 32k block size and the DiskLib volumes with 64k block size. We have run a new DASH Copy in the SP to create a new dedup baseline from the previous backed up data. And the plan is to make this DASH Copy the new Primary once all data is available. A standard re-baseline operation, that usually get better dedup ratio with an updated DD-Engine. The backup data is mostly Hyper-V vm’s. In this case the Data Written in the old copy was 9TB and the Copy stopped att 18TB in the new MA as it ran out of resources - DiskLib Full. This was unexpected. Now we are thinking about doing Move DDB and MountPath but if there is a general Deduplication degration we are not sure if this will work, and if we will run into the same issues again. Does anyone have a similar experience or knowledge about this issue and a recommendation on how to move forward?I have done both new baseline

Creating a Selective Copy Using a Library (Enable Deduplication)

Hi Guys, I finally found the exact article that describes a solution I wanted to implement and am seeking opinions to do this or not. Basically I want to create multiple Selective Copies under a storage policy and associate with different subclients/computers to meet a client’s tiering model and different retention. Because I also want to implement Deduplication between the Primary and each selective copy, Weekly and Monthly, I’m weighing an option to Create Selective Copy using a Library instead of using a Storage Pool. In the article below;Article: https://documentation.commvault.com/commvault/v11/article?p=119730.htmStep 17b, can I select Partition Path as a normal Windows folder e.g. D:\<randomFolder>. If I create additional selective copies under the same storage policy, can I use the same D:\randomFolder> to deduplicate data between Primary Copy and additional selective copies or I have to create a D:\<randomFolder1> and so forth for each copy. I ask because I do n

Creating a Storage Policy Copy with Deduplication vs Creating a Deduplication Enabled Storage Policy Copy

Hi guys,This might seem stupid but I’m a bit confused by these two documents on the Commvault website that talk about deduplicating policy copies. If I’m getting the below articles correctly, the difference between; Creating a Storage Policy Copy with Deduplication https://documentation.commvault.com/commvault/v11/article?p=12446.htmand Creating a Deduplication Enabled Policy Copy https://documentation.commvault.com/commvault/v11/article?p=14132.htmis that the former is created using a Storage Pool (dedup engine exists) whilst for the latter the Deduplication location is not an existing dedup engine (storage pool) but just a local folder on the media agent? If the latter is correct and I want to use it to deduplicate additional independent copies e.g. Weekly Fulls and Monthly Fulls on independent libraries against the Primary Copy data, is there a downside to it?Need some assistance on this.

Selective Aux Copy reached Pending status at 98%

Hello,There still seem to be more problems :-(Next time I launched an aux copy for two more tapes of the same Storage policy.It reached 98% and Pending status. no error at allHe took the same tape as in the previous process.I killed the process.…I have delete content of new LTO7 tape because, process aux copy not finished to 100%Now, I run auxilliary copy with Backup period in which there are backups for four tapes, but Job is completed and “no more data copied”Whether it is possible to run Aux copy from same tapes LTO4 twice to a new different LTO7 tape???

Tape usage - Size of Stored Data

Hi,Until recently, ~1 TB of data was stored on all our LTO4 tapes.I recently changed 2 things:I created a Global Secondary Copy Policy I enabled software encryption for the (secondary) backups to tape (Re-encrypt, BlowFish, Key length 128, No Access)Now, only ~750 GB of data is stored on all tapes before they are marked full. A decrease of 25%.Is one of these two changes a known, proven and expectedcause for this decreased usage of the tapes?Thanks!

Extended retention or not?

Hello,Sorry I can’t correct the title are/or :)On a Storage policy that has deduplication enabled I have this message and I understood why.My question is :can I unselect the Extended Retention Rule 1 set for 90 daysand increase the basic one to for example to 90 days, if yes, how many cycle is good to have for 90 ?

Deduplication on Independent Copies for Azure Cloud Backups

Hello guys. I’m looking for some advice/tips on how best to configure additional selective copies in a storage policy and ensure they are deduplicated to avoid rewriting the same blocks on cloud storage. The Primary Copy is deduped and goes to Library 1. I want Weekly and Monthly copies to go on Library 2 and 3 respectively with each copy disabled. I noticed I can’t use the Global Deduplication Policy being used by the Primary Copy on the additional copies. Anyone has some thoughts on how to tackle this? I’m not a fan of using Extended Retention on the Primary Copy as and set Weekly and Monthly retention on one media/point of failure.

Aux Copy performance

Hello, we would like to tier out the data, wich is stored on the disk library to an Huawei Object Storage. I created a secoundary copy and configured an aux copy schedule. The problem is that the disk library disc space is running low because the job is not as fast as I was hoping.The amount of data for the copy job can be up to 10 TB.Is there a solution to speed up the aux copy job ? The Media Agents provide 2x10 Gbit cards.RegardsThomas

Mount Path move failed

We are trying to move a mount path to a new media agent, but it’s failing ever since we stopped the job. The disk became full resulting the data migration job being stuck for weeks, so we stopped the job and freed up space. However, every time we try to restart the mount path move it fails.We did the following to troubleshoot:Run disk defragmentation Verify disk and mouth path are online Validate mouth path Verify no disk maintenance task is running General sanity checks The error that we get is:Move Mount Path Job Failed, Reason : The mount path is under maintenance and hence cannot proceed with the move operation. Source: <MediaAgentName>, Process: LibraryOperation Can anyone tell how to fix this error? How do we get Commvault to see that the disk is not in maintenance mode?

No Index Backup in last 30 days

So the ticketing service is kind of being slow with this process, and i want to know if I can do this on my own. We have an alert for No Index Backup in the last 30 days. I don't know why they are not storing the index information on the media agents but storing the index data to tape. How do i get a client that is on this list for no index backup to get the index to backup to the media agent so i can get rid of this list?

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?

Migrating to new Media Agent Server

I’m looking to migrate to new Server Hardware for one of my Media Agents and looking for best approach and minimal downtime.Was thinking I could setup the new hardware with the media agent role/software and start to move mount paths to the new server. Once all mount paths have been moved to the new MA I can then update my storage policies to point to the new MA. Is there anything else I need to look out for or would need to do?Any advice or knowledge on this would be great.Thanks

DDB corrupted on Windows server and sealed DDBs

Hello, I would like to request your help as i’m quite new and have only basic knowledge of backup systems.After reading the commvault documentation available online and tried to troubleshoot the issues, they were narrowed down to 3: Sealed DDB are not aging out. When I try to run a verification of existing jobs on disk and deduplication database it says DDB is corrupted. we have our disks full, as the backups all have stopped.When i run the data retention forecast and compliance report it says “BASIC CYCLE” as reason why jobs are not aged out, i have this dedup policy to age out jobs after 1 cycle, so i guess that if i do a full backup, the previous will be aged out.. except i dont have any available disk space. Also I was unable to find a DDB backup as it seems there was never one to begin with. Should i reconstruct one new from the group up? How can i reduce the size of sealed DDBs as they are quite old.

Does convert to DDBv5 also enable Horizontal Scaling?

Hi all,Sorry for yet another question. But I love the quick feedback I get on this platform! :-)I have a customer running DDBv4 who wants to leverage DDBv5 with Horizontal Scaling.I know that we have the ConvertDDBToV5 workflow, or alternativelywe could convert the DDB manually.But would that also enable Horizontal Scaling automatically? Or is there some separate procedure required for getting horizontal scaling?Thanks in advance for your reply!

question about setting up exchange db client to backup all passive DBs.

We have four Exchange servers. Each DB has a passive and active copy with them being on different servers. We installed the media agent and a backup disk on the exchange db server. Usually i know what DBs are passive on each server so i setup a subclient on each one so the back up will run from the passive disk directly over the SAN to the backup disk without using the network. However sometime exchange admins will do patching late at night and the DBs will failover and they wont fail them back til later. when this happens the db backups are much slower. I want to avoid this by configuring each subclient to only backup the passive DBs that are on the same server as the media agent/backup disk. my goal is to never run backups over the network even when DBs are failed over to other servers. is this possible?

Data Domain DDBoost feature

My company is planning to do a tech refresh on our aging data domain to a newer version. We also highlighted that we’re having backup slowness issues on some of our large Oracle databases & some NDMP backups. Our current configuration is backing up to a VTL located in our data domain & no compression or deduped are enabled from Commvault layer.Dell’s sales team advice us to purchase an additional license for DDBoost for the new Data Domain. This is because DDBoost will be able to perform a very good dedupe & compression rate from the source level before transferring it to our data domain, thus saving the time it took to transfer via network.However I’ve been checking around Commvault’s KB and looks like commvault only works with BoostFS & not DD Boost. I haven’t check with Dell yet regarding this. May I know has anyone implemented DDBoost on your environment for backing up databases/vm & NDMP?
