Storage and Deduplication

We wanted to move backups of clients with disk library from one commserve to another and would like to continue the backups to the same disk library on new commserve. How can we achieve this?

Looking for assistance on configuring new DELLTape Library

Hello,we got several LTO4 Tapes from a customer to recover files from it. The IT-Department doesn’t exist anymore and the contact person has no clue about anything. We successful imaged 2 Tapes an in the first sector we saw “CommVault Media Label… CommVault Systems Galaxy” Entrys. What brings me here. ;-)How can we restore files from the tapes, what do we need. Thanks in advance.

lets imagine situationin site A we have 2 MAs:  A1 & A2  and client group A which inside are A1 & A2 in site B we have 2 MAs: B! & B2  and client group B which inside are B1 & B2 we have AUX copy   which sends data from site A to site B  (mean src MA: A1,A2 and dst MA B1,B2)so we have4  traffics / streams  A1 > B1 & A1 > B2 & A2 > B1 & A2 > B2 on level of group A i set network throttling X Mbps and select as destination/ remote group B - here important i also checked “All clients share allocated bandwidth” Mine question is if X network throttle more or less equally touch / control all 4 traffic described above or only in pair by SRC ma : A1> B1 & A1 > B2  and Independently  A2 > B1  & A2 > B2 on numbers if we set X = 20 Mbps we have situation1:    A1 > B1 5MBps & A1 > B2 5Mps & A2 > B1 5Mbps & A2 > B2 5 Mpbs  orsitaution2   A1 > B1 10MBps & A1 > B2 10Mps  and  A2 > B1 10Mbps & A2 > B

Hi Team,Greetings!!! In our  Tape library there is an error for one single tape “The request could not be performed because of an I/O device error” and the Media status is showing “full” but actually this tape is not full. after that  this tape is not writing any more.please see the tape size detailsNative capacity of Tape: 11.72 TBSize of stored data:1.31 TB onlyCommServe current version:11.28.24Could you share any solution for this issue

We install a small Commcell test lab (1 Commvault server, 1 MA and 1 client) with DR backups and aux copy to Metallic recovery reserve (MRR). My plan is to test a full site crash.Since I have a DDB backup and data copy in MRR, I should be able to reinstall a Commcell using latest DDB backups and resync data.There’s a few steps I’m not really sure about. here’s what I have so far:reinstall CV serveur using DDB backup set downloaded from cloud.commvault.com Apply licence reinstall MA add MRR storageNow, how should I proceed with the data in MRR. My MA is empty. How do I sync back from MRR?

We are trying to observe how commvault sends delete requests.Does it leverage  ‘versionID’ header in DELETE operations for s3 buckets’ objects?Or the delete requests are more of non-versioned delete requests?

Howdy folks,Our current environment:One on-prem mediaagent connected to SAN for primary backupsOne off-site mediaagent with storage and jbod for DROne Commserve265TB of deduplicated data, 1 DDB, nearly 11PB of undeduplicated dataOur goal:We want to add a second on-prem mediaagent (with its own DDB and index cache) to work in tandem with our current primary mediaagent. Our idea/hope/goal is that both on-prem mediaagents (one existing, one new) would be under the same storage, deduplication, and copy policies and Commserve would load-balance jobs between the two. Both of these would then copy over to our third (existing) off-site mediaagent.  We met with our Commvault rep during purchasing of the new mediaagent and he said it would be possible, but didn’t give us any specifics. Now that installation/setup is here, I can’t find any documentation on how to actually accomplish this. I’ve found everything I need to prepare for installation, and install the Commvault software on the mediaagen

Dear all,I am currently struggling with the following topic, I hope anybody can help.In our Commvault Infrastructure we have 3 Media Agents, each with its own local Library and Deduplication Engine. On each Deduplication Engine we have 3 Dedup Databases, named DDB_Files, DDB_VMs and DDB_Databases.I am now adding a new Media Server to the platform but I can’t figure out how to create the 3 DDBs for the local Deduplication Engine, to reproduce the configuration of the existing MAs. May anybody be so kind to suggest me how to do? Thank you!Gaetano

Hello All,We have 2 Media Agents where the backend storage is going to be replaced with the advanced storage so that the support is available from storage point of view. We have 2 different libraries from two different media agents. So now my question is how will I move the data from the library to new library within the same media agent. The backups are running continuously and they will be running without any break. Let me know if you have reference links or steps to perform these steps.RegardsKishore 

I’m wondering how to add an incremental SP into a working environment without causing mission critical BUs to fail.I have 4 “very large” NAS/NFS subclients which all go to a SP which currently has just one S3 destination for all jobs. It was becoming impractical to send all fulls and incs to tape and the business requirement is just “daily backups to tape” so we do synthetic fulls, but, even occasional synth fulls then would need to copy to tape, all wasting tapes due to cycles, etc. I had talked to one of the guys in support about this and it sounded “easy enough” but when I try to deploy, things don’t look like it was described over the phone.So, what we would really like to do is have only incremental jobs copied from that S3 copy to tape. No fulls, ever go to tape. We also don’t want to skip any incs going to the existing primary bucket.I thought it would be as simple as creating a new incremental policy but I have observed that if I have any Incremental SP’s the actual option to s

Hi Everyone! I am looking to see if there is anyone else that is backing up Microsoft AG clusters with nodes that are hosted in different geographical DCs? We have the MSQL AG client configured at the moment to backup to “PLAN - DC1” but when the DBA’s failover the cluster to another node, the backups are being transfered across the WAN from “DC2” to “DC1” Should we not configure the backups using the AG for these DBs and confgure them on the clusters nodes instead and configure the storage polices to point to the Commvault Plan for that site or is there another option? Thanks for your time! 

Hello everyone,Two months ago we put two new media agents into operation with a new backup storage. The two old media agents were shut down. Since you don't want to restart the old media agents due to the old operating system, the question would now be whether it is possible to remove the mount paths to the old media agents (LUN's) from Commvault? The data has a retention period of 30 days and this should also have expired. If we could open these paths like that, that would be great.RegardsThomas

Team , how the hypersalce x , media agent handle the jobs when a failure of one job occurs , i have performed a testing where a job was running with media agent 2 of hyperscal node 2 and i shutdown the same node , 1> the running job is on running mode - and no progress  2> i started new job and it completed successfully started the node 2 and still no progress on that job and it failed .why was it not assigned to any other media agents - and why the job is handled only by one media agent - i can see restore jobs used all 3 media agent but backup is by one , do we have control on this . 3> after the nodes came up , there was a restore job happned from node 2 to node 2 - may i know what basically getting restored ?

I’m backing up a few NAS subclients that are between 10-30TB each.Currently they are scheduled to do a synthetic full backup every weekend with incremental backups every weeknight.These are then aux copied off to tape.Because of the very low change rate in reality probably 95% of what’s written to tape each week is exactly the same as the week before.The speed of the aux copy is becoming an issue as I don’t seem able to aux to two drives but drop down to a single drive when other backup jobs need the second drive.So my question is whether I’m stuck in the past in a traditional GFS mindset and I should look at the “Automatic Synthetic Full” backup option?All backups are kept on disk and tape for a minimum 30 days and extended retention keeps monthly full backups for a year.We have a stupidly quick media agent with an NVMe dual partitioned DDB so in theory we’re doing best practise so the synthetic fulls only take an hour or two each but the 5 days auxing the lot to tape is painful and i

We have a disk storage and we have a limited space on that disk and don’t have any plans to extend the storage on the disk. In weekends the storage utilization is high and could you please help me to process to reclaim the storage on the concern disk.

Hi! Trying to understand selective copy connected with database agents (mysql and psql). My config is : two storage polices (one from data and one for log)  full aux copy from primary to secondary DC selective copy to tape (for both log and data SP; first full backup each week with 4 week retention, first full backup each month with 6 months extended retention) What we see is not consistent across DBA agents and logs are not always copied as we would expect together with data ; postgres (FS based) write data and logs to separate storage polices, selective copy works as expected psql (with intelisnap) not execute log backup during full, logs are not copied to offsite copy, recovery need to based only on logs present on filesystem during snapshot mysql (by xtrybackup) is doing log backup to same SP during full, so logs are not in storage policy in what we expect to be and are not copied to offsite copy, during recovery only data is restoredDo we have any guidance on above? Or configurati

Hello,On our VMware infrastructure, a Windows 2012 file server contains five datastores (LUNs) and we want to distribute these LUNs to new file servers. From the vCenter, we planned to detach the LUNs and reattach them to the new server. However, on each of these LUNs, several TB of files were archived and stubs replaced the files. What should we do to ensure that nothing is lost during these manipulations?Thank you for your help.

I have 3 locations worldwide with different companies. I want to back up these locations with a secondary copy of the backups at the main location in a storage pool.  Is this possible with an auxiliary copy?or what is the best way to do this? 

Hi i have a question about DDB assignment.In my environment i have 2 file DDB for same disklibraryI think it was created by mistake when creating a new storage policy. So my question is can i remove (seal) the 1 DDB that i dont need? and will the storage policy using that DDB switch over to the other DDB? they are both under the same Global DDB.the reason this is a problem is that this DDB is located on the comserve nodes and they dont handle this load well. i could of course move the DDB but i would prefer to remove them instead.

Hi All,is there some possibility to perform the action of “pick data for verification” for a job of a Storage Policy with a command line? Maybe I have to do it on a lot of jobs and I’m looking for a script.Any help is appreciatedThanks

i have a DR site with a vmware vsphere cluster. I use commvault replication to this DR site. I would like to monitor how much date is transferred after compression and dedupe.Where could i found this information ? I have a LAN to LAN 10Mb/s link and i want to understand what is transferred over the WAN.Regards

Hello, What is best practices Software Compression setting to reduces storage space? Automaticly its on SP but when are you suing compressie on Client and Media Agent? Or maybe turn compression off?

currently I backup S3 bucket with managed key, plan change the key to CMK, will commvault support S3 bucket backup with CMK?
