Optimized tape utilization

We make daily backups of our servers.Every month we write the backup data on tapes.The retention period for these tapes is one year.For December, we create an end-of-year backup with unlimited retention time.Our goal is to have an annual backup for December and reuse the remaining months' tapes after one year.Due to server retirement, there are monthly tapes that we cannot reuse without first deleting the contents (Retain time until: infinite). If we do so, we lost data.Is there a solution to this problem?

Certain tapes not written to after initial writing and before appendable date setting

In my organization, I have two HP MSL4048 tape libraries containing two Ultrium drives which uses LTO7 tapes with a capacity of 5.47 TB. The firmware for both libraries are the same. The Use Appendable media setting is 14 days.For the two years, for one of the tape libraries, about once every two months one of the empty tapes gets written to but it doesn’t fill up to the capacity. And if in three days the tape is not written to, then it will not be written to at all and will choose a different tape, even though it’s before the appendable setting of 14 days, and its media info properties clearly states Yes of it’s appendable. The other tape library on the other hand will always fill tapes to its capacity.Attached file no_writing_prematurely.jpg shows such an example. The last time it was written to was on 12/6/21, and the tape is not full and there’s 7 more days to be appendable. But it will not be written to at all. As mentioned, this occurs about once a month with a random tape. I won

DDB Data Verification on cloud enviroment

Hello,I’m wondering what’s the proper approach to data verification in native cloud environments. The environment is built within the cloud, CS, MA, Cloud Libs etc. are placed in the same cloud solution, so the infrastructure traffic basically stays within the cloud. The only reference that I’ve found in the docs was:Tip: By default, the data verification schedule policy that is created by the system is not configured with data mover MediaAgents that use a cloud storage product, because the read operations from the cloud are very slow and are performed on low latency media. If necessary, you can perform the data verification on the cloud storage manually.To run data verification on data that is stored on archive cloud storage, first recall the data to the main cloud storage location. Then you can run the data verification job on the recalled data.https://documentation.commvault.com/11.24/expert/12567_verification_of_deduplicated_data.html But in this case the MediaAgents, are not data

VSS DDB Backup Failures

Hey all - we are having a VSS failure for our DDB backups. Providers look fine but seems like there is some sort of issue with it.Windows Application Log error says the provider could not be started. The provider referenced is the Galaxy VSS Provider Service. It is telling us there are no associated devices.This has been working just fine and then just randomly started failing on Nov 22nd. Nothing has changed on the media agent.When running the vss creation manually - the error is VSS_E_UNEXPECTED_PROVIDER_ERRORCustomer will most likely open a ticket but wondering if anyone has any ideas?PS- we rebooted just for the heck of it...

Cleaning tape deprecated

Hello,I would like to discuss the issue with a cleaning tape.Our cleaning tape is marked as deprecated and it is not possible to use it for cleaning anymore. Is it possible to somehow reset the counter for number of uses? We tried to delete the cleaning tape and rediscovered it, but the Commvault remembers the number of uses. The cleaning tape seems to be new, on the tape library there is written, that it was used almost 60 times.Any help much appriciated!

Backup DDB to tape?

Is there any reason (technical or best practise) why the DDB policy can’t backup to tape?It’s defaulted to our disk library which is on the same MA as the DDB.Tape feels a bit safer

Reducing data retention (Aux copy)

Hi all, I start on this community, so thanks about all help you can give me. Near 2 years ago, we make a mis configuration on our infrastucture.Result : We have datas on Tape, which have bad data retention date.When I modify the retention date of jobs, I have 2 different behaviors :When I increase retention date : COMMVAULT show the right date When I reduce retention date : COMMVAULT don’t make any changesWhy ?How can I expect that datas expire at the right date ? My COMMServe is in 11.24.21 Thanks in advance

I’ve used the subjected workflow some times and it’s working.However when I looked at it today it seems it was changed @ some point in time.The documentation isn’t corresponding to whats shown in the GUI.It seems that it’s not possible to target a specific cloud library any longer.Is it just on my installation this has changed, or anyone else seen this?Screenshots provided below.//Henke

how to create metallic license library capacity dashboard widget

We have CommVault Complete licensing and also Metallic Cloud Storage Service (MCSS) licensing. However, the Command Center dashboard lacks a widget for Metallic. Can someone share how to add a widget that would display the %used of a library? This would effectively show MCSS as a % of licensed use. The existing Current Capacity widget only shows the % of licensed Complete usage, not the % of storage used; the MCSS library falls into the latter category since MCSS is not a “Complete” accounting of backup potential, it is an actual % of backup used. From dashboard:From Storage>CloudSo it would be nice to see the cloud library as a pie chart, similar to the complete licensing in the Current Capacity widget. How do you make widgets and put them on the dashboard?

Synthetic Full & Aux Copy Performance

I do several 10-20TB synthetic full jobs each week which are then aux copied off to tape on a global tape copy policy with a single stream (one LTO drive) with multiplexing enabled.I noticed that under the advanced settings on the synthetic full job the “Use Multiple Streams” option is NOT selected.What I think this means is that each 10-20TB synthetic full backup gets written to disk as a single stream which means it gets aux copied to tape as a single stream.If so am I right in thinking I want to enable this setting so the synthetic full jobs get written as multiple streams as this means they’ll get aux copied as multiple streams?I’m going to be moving the DDB to a new NVMe volume which seems a good time to review things.We’re on 11.20.73.Thanks in advance.

Aux Copy size and throughput summary for a given period

Hi Team, We are in the process of evaluating our recent Aux Copy performance to our DR site as we are scoping for future capacity and bandwidth requirements. It would be very useful if there was a suitable report to show me the rate of throughput and the amount of data copied in a summary format, similar to what you see when running Job reports and aligning by Storage Policy (as opposed to client). Surprisingly, I can’t see a summary of the Aux Copy results in any reports.Although the Aux Copy entry in the report shows the data copied, and the overall throughput it is only for each Aux Copy job. You can see below in this example, where we have a few days worth of Aux Copies:- What I really need is a report with a summary line at the top of all data copied and the overall throughput figure.At the moment, I need to export into CV and then reorganize the fields so I can add things up manually.There is one other report which might also be of use, which is the Jobs in Storage Policy Copies

Office 365 Backup Storage Calculator

Is there a calculator (or formula) to estimate the required backup storage capacity for Office 365 Backups (Exchange Online, OneDrive for Business, SharePoint Online & Teams)?For “normal” backups (File, VMs, Databases) there is such a calculator (Link), but I haven’t found anything regarding Office 365.How do others run such capacity calculations for Office 365?

Implementing S3 combined tiers on AWS

Hey all We are creating a secondary copy and writing to a combined tier library. When we create this, do we need 1 bucket or 2? I only created 1 bucket and specified the combined tiers. Does an additional bucket get created - or a different folder within the bucket created and that gets changed to Glacier?We are planning on using S3-IA/Glacier for the 2nd copy.I guess I just want more specifics on what exactly happens in this process.

DR backup to CV cloud

We are currently preforming a DR backups to On-Prem (multiple locations) and CV cloud. As viewed in cloud.commvault.com it appears that we are limited to only 5 iterations of the CV DBs. In “DR backup” options we have 20 set, but that seems to only be On-PremQuestion> Is there a way to expand the amount of CV cloud backups retained?

Data pruning after the DDB Seale in the cloud wasn't performed. (Micropruning Off)

Hello Commvault Community, I need help with data pruning issue after Seal DDB (every 3 months) - micro pruning is disabled, but jobs shouldn't be held for that long anyway. (screen1.png) Micro pruning is disabled due to the cost of operations in the Cloud Storage.As I remember correctly, Commvault also recommended disabling micro pruning on the cloud library. We have generated a Forecast report, where some of the described Jobs are actually kept by not being copied to Secondary Copy, but it's about 30TB, and for example (screen2.png) it says that the data is 126TB within one of the Sealed DDBs. There are several such databases and a total of about 600TB of data remains in the Cloud, which should probably be deleted. I am asking for help in solving the problem. Screenshots and Forecast report are attached. Thanks & RegardsKamil

Delete Mount Path associated to DDB

Hello there,I’m have a minor issue, I cannot delete unused Mount Path, since it’s used by DDB. There’s a few of MPs under Disk Library dedicated to this DDB. In the DDB properites I can only remove whole Disk Lib, which is not the point. CommCell says that in order to delete this MP, I need to delete each Storage Policy Copy which is referencing to this Disk Lib. It’s not an option neither. Logs are saying something similar: EvMMConfigMgr::onMsgConfigStorageLibrary() - Error [470, Mount path is used by a Deduplication database.] occurred while deleting the mountPath[xx] ###### MLMMountPath::deleteMountPath() - :mlmmountpath.cpp:6170: Failed to delete mountpath [xx] due to error [470, Mount path is used by a Deduplication database.].###### MLMMountPath::deleteMountPath() - :mlmmountpath.cpp:5593: Failed to delete MountPath from database for Id [xx] due to error Mount path is used by a Deduplication database.:470 Do you have ideas, workaround to delete single MP in that situation?

Backing up Exchange Databases from HD Library to tape

We had to back up some exchange Dags for short term retentions to an 3Par Disk library. The Mount Path is from one of our media agents where i can see what's stored on the 3Par. My boss wants me to back up the month of September that we have on disk to tape, so we can clear it out from the 3Par for another month of Storage. Would the best way to back this up to tape would be to create a subclient on the media agent the drive is mounted to , target the Data Chuncks for the time of the month he wants backed up, and assign it a storage policy that will back it up to tape, or will that not capture the data we want from the 3Par?
