Storage and Deduplication

Hi Community,We have Data Domains as our primary storage for Commvault and tape for long term retention. We are looking to replace the tape libraries within the next year with DD Cloud Tier. With DDBoost now fully supported as access and client libraries does anyone know if and when DD Cloud Tier may be integrated and supported.

What’s the command to get the gluster version ?For the OS we run uname -r which gives us the following out put.3.10.0-1160.108.1.el7.x86_64Looking for the same detailed output in a gluster version command. We should be running version “6.0-63.el7rhgs.x86_64” and would like to verify that we are. Thankshttps://documentation.commvault.com/2023e/expert/hyperscale_1_5_platform_version_1_2403.html

Hi Everyone, We Currently have Commvault commserv (All VMware Environment) targeted to HyperScale appliances. However, HyperScale 1300 is EOL/EOS. We have a spare HP MSA 2050 SAN storage available and require your advise before we configure it as a library.As HP MSA being an entry level storage, is it recommended to be used as target library even though disk speed are 7k for  HyperScale and HP MSA? Would there be performance issues as storage needs to mounted to additional server server to be used over 10 gig network as VMware does not have SFPs? Would configuring backups on HP-MSA give us same dedeuplcation ratio as that of HyperScale appliances ?

The process of setting retention to half what is actually required, combined with the periodic sealing of the DDB seems clunky, and results in significantly higher storage usage - can we expect any improvements to that process?Where an existing block is referenced during an operation, could it be more efficient to just extend the Object Lock retention for the associated S3 Object?

I have created a disk library in our dev environment which is using it’s own separate volume. it will be used for ddb backups. If I want to increase the capacity do I have to add a new volume or can I just resize the underlying volume in linux ?  

DearI need to carry out a survey of the growth of data volume in my backup environment, a comparison of growth over the last few years.Would anyone have a step-by-step guide on how to generate this report in Commvault?This information will be necessary to justify the calculation of data growth projections for the coming years.Thanks in advance for your help.

we previously use cqcclassic.commvault.com/Dedupe/Design  tool. Now it cannot find it. if anyone have an idea? 

There is a new physical tape library configured in this environment (HPE MSL G3 2024) with 2 tape HPE Ultrium 8-SCSI FC drives. The tape library was added in Commvault and few auxiliary copy jobs performed:1. With the hardware compression disabled in Commvault storage policy copy data path configuration. The size of data on the first tapes was 10 TB.2. With the hardware compression enabledin Commvault storage policy copy data path configuration. The size of data on each tapes was 20-21 TB.The backup data type is VMware backups.Our question is why Commvault is not placing more than 30 TB on each tape, considering they are LTO8 and hardware compression is enabled? This customer has another Commvault environment  , with similar backup devices and same settings, they are able to accommodate between 30 -40 TB.

Hi Good Day!I’m planning to deploy new HSX servers. I have a question about the DNS record requirement. Pls help.Environment detail:Bond1VLAN1.bond1 (CS-Registration)  -→ This will be used for connecting to Commserve and VMware backup, DNS, and MGMT.VLAN2.bond1 (Data Protection)-→ This will be used to backup Agent-based backup. Bond2 -→ This is for the Storage Pool. DNS record not required.DNS record planning to create for the bond1 interfaces.VLAN1.bond1: hsxcsreg01.smaple.com , hsxcsreg02.smaple.com, hsxcsreg03.smaple.comVLAN2.bond1:  hsxdp01.sample.com, hsxdp02.sample.com & hsxdp03.sample.com   ? Do I need to create a DNS record for the Agent-based backup sub-interface? In this context, I doubt I can have a DNS entry for a sub-interface other than the CS registration.  Please help.

Ok, let’s get straight into the topic. The disk containing the Media Agent Index has been accidentially removed. What are the possibilities to recover the lost Index on this specific Media Agent? Thanks for any help. RegardsCSS

I’ve run into a problem trying to mount a 54.4TB FC LUN presented to a Linux MediaAgent. A single partition was created using the ‘parted’ utility, and then an XFS file system with a block size of 64k was created using the ‘mkfs.xfs’ command. I'm receiving the following message when trying the mounting xfs filesystem.mount: /mnt/cvstorage: mount (2) system call failed: Function not implementedAny help would be appreciated.

Good Morning,We need to restore data from S3 which is secondary copy with a retention of 90 days. Last backup was a year ago, so retention period is expired.Obviously, the jobs have been expired but if we check content on S3 we can see the data is still on it.However, if we check content from S3 library on CommCell the data on media is not available.Is it possible to restore this backups by anyway? Thx in advanced and Regards.

Where can we find the correct number of tape storage used, if its on our Commserv, Command Center, or Webconsole? Thanks!

I have a question from our storage administrator that I think I know the answer to but would like to confirm.  Is there a way to backup data and have the original/source data deleted?  We use Isilon for our storage and we would like to back up the data to a Primary target, but have the original data deleted afterward (I guess the Isilon doesn’t have a native tool to delete large amounts of data).  The only option I know of would be to run a post-process script, but is there any other options that I am unaware of?Thanks!

Hi All,We are configuring GFS disk to disk to tape (different tape media). Please find the below requirement.Requirement 1: first storage policy will configure daily Inc and weekly full for first disk keep 7 days Requirement 2: first disk daily Inc and weekly Full go to auxiliary copy of second disk keep 28 daysRequirement 3: second disk daily Inc auxiliary copy of daily tape media keep 28 daysRequirement 4: second disk weekly Full auxiliary copy of weekly tape media keep 28 daysRequirement 5: second disk Full (end of month) auxiliary copy of monthly tape media keep 12 monthsRequirement 6: second disk Full (end of year) auxiliary copy of yearly tape media keep 2 yearsRefer above, should I create as below?(Requirement 1) create Primary_Full storage policy with Primary_Inc Incremental storage policy first disk keep 7 days(Requirement 2) Primary_Inc storage policy create auxiliary copy select All Backup to second disk keep 28 days(Requirement 2) Primary_Full storage policy create auxiliar

HiGood dayMy backups were running before now, all of a sudden they started failing because of this error: Unable to communicate with remote machine {Linux media Agent} to start data pipe. Please check the following:1. Network connectivity exists between client and remote machineProduct servuces are running on remote machine. Firewall is setup properly between client and remote machine Error [Connection failed on oracle_dba with these errors: 1 Couldn/t complete tunnel connection to tape_linux)server on 192.168.1.112:8413: No route to hostAll these seem like network issues. I tried to add entries into the host files of all clients affected. It still keeps failing. This is the caseI want to backup oracle files and instances to tape, via a linux media agent. The backups ran some days ago, and all of a sudden they have failed with the errors i quoted up here. Someone should help me resolve this challenge. Thanks.

HiGood day.I have configured my Commvault backup to write jobs directly to tape (not auxiliary copy)However, I noticed some things the client is an oracle database. I installed the file system agent and oracle iDA I configured the file system agent to backup some contents in a path, and the Oracle iDA to backup instances and archives.However, the files were successfully backed up to the tape drive. The oracle instances failed. Error is in screenshot.I tried to click on the error code, it was blank. I also know that Commvault should be able to backup a storage policy to a tale, regardless of the workload type. Is there a way to resolve this issue? Its been on for days.

We are in the process of upgrading clients to Commvault 2024 for the added security benefits as well as the potential storage savings. In the change notes for Commvault 2024, the changes state for backups other than database backups, “each backup job will back up only the new and modified items and create a full recovery image. Therefore, running repeated full backup is not required.”I know that existing plans remain unchanged and follow the old format, so I imagine the change process is just associating existing entities to a new plan. This sounds a lot like a synthetic backup, so it sounds like it will create a new full backup to start a synthetic chain which might be storage intensive depending on the environment and their storage constraints.Am I understanding this correctly? And if so, would I also need to be conscious about updating the synthetic full backup schedules via the CommCell Console?

Hello,I made several plans with two backup destination (primary and secondary).On these backup destination, the retention periode is 3months, but when i look to restore data, i see that i can restore data from beyond 3 months.Why ?The Data aging is runing daily, so i don’t understand the problem.Also, some plans respect the retention period and other no. 

Hi,Is there any file in an mountpath that can be deleted to gain som space temporarily?The data in the mountpath is Deduped.

Hi Commvault people,I am looking for some advice on a recent volume migration, and Commvault’s behaviour afterwards.So we basically upgraded a large fileserver. 60 TB of data across several volumes.The data on “Server 1” is already under dedupe.When we migrated the volumes to a “Server 2”, although we are obviously creating new subclients, and we have to kick-off new fulls, I was surprised to see these new backups writing large amounts of data.Previously, we were writing minimal amounts of data, literally a few GB’s, despite the volumes being around 15TB (very small rate of change).Given that dedupe is in play, and we already have the blocks of data held in the store, then why are we writing so many new blocks? To put this in context, we are writing maybe 30% of the application size, which is a few TB’s, compared to the previous few GB’s.Hopefully that makes sense. Basically, i am trying to work out why Commvault is not using pre-existing blocks for these new backups.Thanks

Do we support Iron Cloud  Archive Storage = Secure Offline Storage (S0S)? How is the data recalled? BOL lists Iron Mountain under supported Cloud Storage, but doesn't have any detail on supported tiers, such as SoS. 

Hey @all, I currently have the following problem, for which I could use help: Since 29 March, I can see in my daily backup report that certain shares of a file server (File Server Agent) have a dark green background and show the job status "committed". Although something is being backed up, the amount of data is very small and the backup is therefore incomplete. However, failed objects are not displayed. It is always only the same shares. Other shares on the same file server are backed up completely. A special feature here is that the file server is unfortunately also the MediaAgent.I get the following messages in the event details of the committed jobs:Error occurred in Disk Media, Path [\\x\x\x\CV_MAGNETIC\x] [Insufficient memory available to perform the current operation.]. For more help, please call your vendor's support hotline. In this case, the x only serves as a placeholder for the path to the backup target. This is followed by several attempts.When the job is finished, the fol
