System Created DDB Space Reclamation schedule policy

Hello,after upgrading from V11FR20 to V11FR24 I noticed a new schedule policy named “System Created DDB Space Reclamation schedule policy” which was disabled by default.I basically know what the Space Reclamation functionality is about, and the policy has all our deduplication engines assigned. But when initializing this policy it finished in less than a quarter of an hour and from the logs only one dedup engine was processed. Another manual start just gives below error message. Can anybody explain to me what this schedule policy is about and how it is supposed to work?

Mount Path does not have enough space/Disk Library running out of space

Hi all,after some time we are facing another serious issue. There is no available space on the disk library. Ayayay.We have tried to find if there are any unprunable jobs. There were some of them and therefore we have set option to ignore cycle retention for disable subclients. Unfortunately, only small amount of GBs have been aged. Now, there is a question what to do next. I have no idea how to find what can be deleted in order to make more free space for the backups. Moreover, there will be quit a big deduplication ration, so even manual deletion of some jobs do not have to be useful. Maybe, one useful information can be that during the last month there were increase in data cca 10TB, which is 10 percent increase. Is there possibility to figure out what data did this increase? Is there any generule rule or useful tool within the Commvault to fight with this issue?

Clarifications after restoring the DR backup to another server

Hi,I restored the Commserver DR backup to another server. This is the first time I’m doing this so after restore I noticed that the configured disk and tape library in the destination server has changed reflecting the disk and tape library from the original server. I tried to add the destination server as another media agent but it is not allowing. How do i proceed to use the tape and disk library in the destination server after the restore?Please advise.

Unexpectedly sending data to storage meant for once per year backups

Hello everyone,I have a question about storage policy configuration.  I take incremental backups every day but Friday when I run a full backup.  Retention is:Incrementals: 2 weeks Full backups: 30 days Monthly fulls: 1 year Yearly fulls: 3 yearsI have a primary and secondary site but the secondary site has a much smaller media agent and I actually ran out of space.  To address this, I added CommVault Metallic cloud storage with the intent that the once per year Yearly Full backups would go to the cloud.  Just today I noticed that 10TB of data is being replicated to the Metallic Cloud storage and I can’t explain why.  Can you look at these pictures of my configuration and explain where I went wrong?Ken

AuxiIllary copy slow and architecture review

Hi, Everyone. I have a customer with this exact problem. After the Commvault refresh/reconfiguration which was concluded some months back, we had some issues backing up to tape which we finally understood was related to the tape drives we were using then. We have resolved the issue with the drives but we are still having copy to tape running at a very low speed (As low as 13GB/hr). Kindly assist us with below. We have sister companies running this same Commvault and we want to know how their setup is different from ours that make them better. We need to review our architecture to be sure the copy to disk and copy to tape can happen at the same time from the primary source. The difference in storage in terms of I/O and disk rpm from what we have here and that of our sister companies. Is there any way i can help them, please?

MediaAgent iSCSI disk library mount marked offline, but is present.

This has been driving me mildly nuts for the past 3 days post a power shutdown for our site.We had some challenges with our storage network, that prevented iSCSI comms for a few hours after we powered up our site post some scheduled electrical work.We solved that by the software equivalent of a power on/power off on the switches in question (two unrelated port channels to our SAN were disabled/re-enabled). Great. iSCSI works again with all hosts.The MA in question, a VM, is borrowing space on a temporary basis from a newer array, as I am doing a lot of migration work, and is mounting the volumes in Windows via iSCSI as opposed to using an iSCSI mounted data store in VMWare which is treated as an HDD by the OS.   Keep in mind, this was all working swimmingly before this past weekend.  For the past three days, CV is convinced that the 5 mount points in question are offline, and do not have a controller.  If you go to the OS, and browse, you can drill down as deeply into the mounted volum

Backup to cloud

Dear colleagues,We have been using CommVault Simpana for many years. And currently we are looking for a solution how we can backup our data to cloud with Simpana. I mean that target of backup will be AWS, Azure or any others cloud providers. I found in the documentation that backup to cloud is possible for CommServer DR, but what about production data?Note: We are looking options for BACKUP to CLOUD (where backup destination is CLOUD) but NOT backup of the CLOUD (where CLOUD is backup source)!I would appreciate any information on this topic.Thanks!

Restore from Commcell Migrated Tape Library

Hi, I am performing a Commcell Migration and in the source Commcell there is a TapeLibrary that we need to migrate to the target Commcell. My question is if the historical data will be available for restores (i.e tapes will be migrated/re-labled as well).  And if using the option “Allow imported media to be reused on this Commcell” means that append will work once the TapeLibrary is migrated or if it is read only and tapes will be reused (moved to scratch) only once all data on them has expired. Regards, /Patrik
