PTL mount/unmount error during Oracle DB recovery

HelloAt the request of the client company, I proceeded with the recovery of Oracle DB backed up in PTL Media as follows.1. Backed up original DB to PTL Media. (SAN)2. The DB backed up with PTL was restored to the recovery server. (Network, using Backup Server MA)Different drives were used for backup and recovery.No issues occurred during the backup.The following message is output with a Failed unmount error during the recovery process:The path is being accessed by another application.Advice : please make sure that no other device explorer application like SAN explorer are running on the machine.PTL devices are used by Commvault only.I would appreciate it if you could advise me on what to check to resolve the issue.

Removing Data from Tapes

Hello, if you have backup jobs on tape and want to delete the contents and reuse the tape, can you just right click the tape and delete contents? I do not know if you right click delete contents will cause any issues in CV with the jobs associated to the tape contents.

what are the password complexity rules for a mount paths service account?

hi, we had a services engineer create a new mount path using special caracters for the services account.how ever it gave an error when trying to login, that there where insufficient permissions.they only changed was the password to be less complex (just basic caracters) so there are expecting they used a caracter that is not supported.i checked the docs and i could not find articles stating this for the a Mount path. i was able to find ones for Commserve livesync and other components.do the same rules apply to a mount path service account? Kind Regards, Thos Gieskes.

Drive reported that media is physically bad

What happens to backup contents from media that an LTO drive reported that It is physically bad? Does the Commvault copy those not-aged jobs from source copy to other media (tape) again or It just prevent reuse the media and retire it after expiring jobs?

Best Practice NAS configuration as Commvault library

I have purchased an HPE StoreEasy 1660 device for on-site storage of our Commvault backups.  As I am working through setting this device up, a number of questions have come up which got me wondering if there is a “best practice” to follow so I can get this in an optimal configuration for Commvault backup storage.I am setting up a RAID 6 array.  The device is running Windows Server 2019.  What allocation unit size would be best? I have the ability to join this device to our domain.  Are we in a more secure position if I don’t join it to the AD domain?  I’ve got ransomware risks on my mind. Any other suggestions?

Drive Cleaning - On sense code option

Hi,Does anyone know what sense codes CVLT interprets to start a drive cleaning job?We suspect that CVLT is starting tape drive cleanup jobs under unexpected and undesired conditions.The option “Set drive as needs on CRC errors” is not checked. In two days we got one new cleaning universal tape that expired. There's another one on the way. A new cleaning tape has 50 cycles. We have a Qualstar model RLS-87120 LTO6 with 5 drives.  There is no automatic/schedule cleaning at the Library side. There is drive cleaning schedule on CVLT. We would greatly appreciate it if someone could contact the developers and find out this information.  The Tape Library supports a specific sense code to inform a system that its drives needs cleaning.

DDB and disk library limits

Hi! Some time ago we set up Commcell dedicated to Hadoop environment. One media agent, one DDB (two partitions, hosted on local SSDs), deduplication block size increased to 512KB, disk library from few external SAN attached storage arrays. And it keep growing :) Few incremental jobs a day, writing ~10TB, synthetic full each 10 days. Without any performance issues so far. DDB Q&I ~ 500ns. Both backup and restore time acceptable. It’s kind of archive, not typical backup solution. Last month I was asked to disable retention, because ongoing migration activities. And it keep growing faster. I assume until 2PB on disk library by the end of year.  So wondering when I’d hit the ceiling for this setup? I know it breaks media agent and deduplication sizing, but until Q&I time are fine everything is acceptable? Or i would hit other limit? It need to survive until end of this year! :)  Some numbers below : Thanks!

DELETE HPT CATALYS

Hi I need your help, in the initial implementation, the customer added a machine running debian 11.00 as MediaAgent, and it is not supported as it only allows to configure HPE-catalyst storage and not the libraries. Therefore the client uninstalled this debian OS from the mediaagent, and now I see that I can not remove the HPE-Catalyst.At the moment I added the mediaAgent with Ubuntu OS and it manages to see both the disk storage and the libraries.The error is about WORM media data.

cloud library S3 versioning VS s3 object lock

On Public Cloud Architecture Guide for Amazon Web Services document.On Page 85, Ensure S3 versioning is disabled, Commvault does not support the use of bucket/object versioning (which isdisabled by default). Enabling versioning will cause storage growth and creation of orphaned objects, whichCommvault does not track or manage (see Using versioning in S3 buckets > for information on versioning).Commvault does not support bucket versioning. Commvault can remove bucket versions created if bucketversioning is accidentally enabled. An auxiliary copy > of all data in the cloud library will be required toremediate.On Page 77, WORM backup copiesConsider utilizing write-once read many (WORM) storage mechanisms provided by AWS (S3 Object Lock, GlacierVault Lock) to provide a protection from ransomware propagation into backup stores.

CV_MAGNETIC Folder with Files of 2018

Hi, We have holds configured in the storage policies to reflect backups to be retained for about 7 days, 1 cycle. Now, when I browse the CV_Magnetic folder, I still see V_## folders from years and months ago in them? shouldn't they be automatically deleted after the 7day retention period or am I just missing a configuration setting somewhere?Can old folders be deleted? Regards,Johana
