Are there any recommendations regarding the hard disk equipment of MediaAgents (disk storage)?

Hi together, I am planning a MediaAgent that has enough storage capacity to be my disk storage. Deduplication should be active, it is Back-end Size for Disk Storage Small (Up to 50TB).Are there any recommendations or requirements regarding the RPM of the backup disks? I did not find anything in the CommVault documentation, only the RPM recommendation for the OS/software disk.Thanks in advance for your help!

Changing Retention times - Estimating capacity

I am trying to estimate the capacity I am going to need when changing the retention time on my Global Deduplication policy - Primary copy from 30 days to one year.If I look at the capacity of the storage policy now, w/ the 30-day retention period, would multiplying that by 12 give me an accurate estimate on capacity I will need to keep that primary copy for one year?  Ex - Primary copy w/30-day retention period = 300GB - changing to 365-day retention period = 3.6TB ?

question on cycles and days

scenario: I have a WORM storage policy (deduplication enabled) of retention 3 days 1 cycleI have run 2 full backups to my storage on same day which completed 1 cycle of retention and with deduplication 7 days of retention is added so total (3+7) 10 days of retention. Will my first set of data be deleted on 11th day since it completes retention on both cycles and days or kindly correct if there is any gap in my understanding here ?

slow backup with Catalys HPEBit

slow backup and restore with Catalys HPE

Hello Commvault, we have been working with Commvault and Catalys HPE for 2 months since before we used Data Protector from Microfocus and Veeam. At first the performance was incredible but as the backups continued we noticed that the backup and restore speed dropped noticeably, reaching the point of restoring VMware VMs over SAN at a speed of 50GB/hour which is extremely slow. I reviewed the documentation provided by Commvault and also by HPE and the only strange thing I noticed is that the number of objects we had in the catalys stores when we used Data Protect or Veeam were from 2000 to 5000 and now with Commvault their stores store more of 40,000 objects and this does not affect the performance. I see that 30% are index objects that run at 1 pm. Please have any suggestions and if you have had a similar problem before.

Cloudian S3 WORM pruning issue

Hi All, There are some posts around this topic but none I could see directly apply.Running 11.28 we have plan that backs up a large system - once a week - that generally takes days to run in order to get the primary copy to disk.Once this is completed one of the AuxCopy jobs is to send this to a Cloudian destination as non-deduplicated data into buckets that are utilising object-lock WORM type functionality.The retention is the same for the Primary and Cloudian copies (14 days).What seems to happen is that when the retention period of the Primary job has been fulfilled I can see that the media agent is attempting to clean up the objects from Primary disk-based and Cloudian copies however as the Primary job took so long to run (lets say over 2 days) then the Cloudian objects won’t be deleted by the Commvault process as they are retention locked until potentially the same time the next day. Commvault makes no attempt to do an extra tidy up the next day and just errors in the log files sa

Deduplication at the Storage Policy vs Deduplication at Subclient

Hi Team,I have a query on how does Deduplication at the Storage Policy compare with setting Deduplication at Subclient level ?I have to set a mediaagent partition while enabling Deduplication while creating a storage policy.When choosing the same storage policy at the subclient level, I could see Enable deduplication Tab in properties to be selected by default as “on client”. Shouldn’t it be “on media agent”?How does it differentiate from each other?

What type of storage array do you use?

We currently use IBM V5000 arrays for our Commvault backup target to land our deduped backups.  We are starting to review other options to see what other fast, cost effective options are out there.  I do prefer to use Fiber Channel connections, but open to options.   Since Commvault is really the brain in our scenario, the storage array does not really need any features, just good speed. What Vendor Storage arrays do you use?  Are you happy with it?

Tape Library Drive Troubleshooting

Hi,I have so far replaced three drives in our DELL/EMC ML3 Tape Lib and still experiencing the same problem. Currently, there’s one valid drive that is working fine - when it comes to the other one, it is mounted and immediately unmounted after a couple of seconds - one try after another in an endless loop.According to DELL, there’s nothing in the library log that would indicate the root of the problem (the log is clean) - they send me another drive and then the case is closed until the issue rises again.I tried swapping the drives in slots but the problem is following the same drive no matter the slot. At this point, I’d like to exclude software-related cause of the issue.Currently, the number of errors associated with mounting and unmounting the drive is way over its threshold; that might be the reason why CV is ignoring the drive completely - how can I reset the counter? Is there a particular procedure I should follow when replacing a drive? I can see there’s an option ‘Mark drive a

Multiple Job Failures: "Mount path does not have enough space"

We’re using Commvault v11.28.48 and have several jobs that are in a “waiting” status and sitting at 10%-20%. The reason is simple: Mount path does not have enough space.I’m new to Commvault (our backup admin left recently and I wasn’t involved in the initial config or daily use) so I may be missing something obvious, but I thought aged data would be deleted automatically. I’ve run the “Data Retention Forecast and Compliance Report” and see the various estimated aging dates, the only thing that sticks out is the last line under the Disk Media Summary:Estimated Size to Free: 9406 GB (this box is green: “prunable job / recyclable media”) Delay reason for physical space cleanup: Archive file has been queued for pruning from the DDBOur Netapp library is 24.7TB with a size on disk of 24.46TB, reserve space set to 100GB, so an extra 9TB would be great. “Enable pruning of aged data” is checked on the library.Am I correct in thinking that 9406GB is data that should be automatically removed (pru

Can a StorageGRID synchronous aux copy have a vault/replica as a source copy ?

Hello Team. I have a storage policy with a snap primary which snaps a netapp a700, and a vault/replica (not a mirror) that CV orchestrates the replication between the a700 and a fas8700. There is a primary copy as well but I don’t want to use this as the source copy for the storagegrid copy; i want to use the vault copy as the source copy for the storagegrid copy. I am creating a new storagegrid synchronous aux copy and the only options to pick for source copy are primary and storagegrid.  The only configuration I can figure out that works is to have a primary copy, which copies the snap primary copy, and to choose the primary copy as the source copy for the storagegrid copy. Is this expected behavior of the program ? Is there any way to configure the program so a storagegrid copy can have as its source copy the replica/vault copy ?Thank you!

Data Written x Size on Media

I've seen several discussions regarding this topic. But I still don't get it. From the docs:Application Size: The size of the data that needs to be backed up from a client computer. Application size is not always identical to the size reported by file or database management tools.Data Written: New data written on media by each backup job.Size on Media: Size of deduplicated data written on the media. Consider the following real job:Job 1 (deduped disk lib is the destination): App Size: 33.4TBData Written: 24.93Size on Media: 7.30 1st question: what is the total size occupied by this job in the dedup disk lib?2nd question: is data written size, before dedup? Does it account for sw compression only? both?3rd question: is size on media just the size of unique blocks for the job (disregarding the baseline?)? regards,Pedro

Hello, guys  I want to perform a secondary copy to tape, and be able to write the data to tow tapes at once, Same data must be written to tow different tapes that belong to two different pools (main pool and copy pool). The idea is to be able to have mirroed data on tapes that will be stored on different sites (customer policy). Data must be read once from primary store (source) and write at same time to diferent tapes.Customer has a library with 3 drives. Any idea?Regards.
