You bet, I went back myself and increased the streams because I saw the same issue with length of time to Aux copy. We've never used Multiplexing and Commvault said to never use multiplexing. I'd like to talk to you offline about the multiplexing topic. You can find me at...
To add to this thread. We had been doing alot of troubleshooting to resolve some other issues with the new v9. The issue about not filling the tapes were for a storage policy that had been modified with more than 1 streams. We had 4 streams. When we combined the streams to 1 the tapes began...
Thanks for the inputs. We're going to be doing the 2010SP2 upgrade this weekend. Our configuration is 2 HUBT servers, 2 CAS servers in an array using a 3rd party NLB device, 4 MB servers in a DAG configuration with 3 servers with 2 active dbs each and a 4th server with a db copy of all dbs...
Quick couple of questions. What version of CV are you on. What model library/drives do you have.
We also have LTO-04 with Dell ML6020 which is a IBM library. I also noticed during the holidays that I had a caouple of tapes that 3MB to 8MB of space. Not every tape was the same and more then...
How's everyone experiencing the new SP2 update. Issues, no issues? Any new issues or resolved issues from the SP2 upgrade?
If you're on Tek-Tips please take the time and effort to pass the knowledge forward for new Exchange changes.

Sorry to all of the IT guys that decided not to use VMMS and Hyper-V and went a different direction because of this issue.
Had to get a support call to Microsoft on this and worked 7 hours working through the issues.
This just recently happened. Situation. Windows 2008R2SP1 server with...
WC,
One of the things we found was our anti-virus, Sophos was modifying the files Change Journal which Commvault picks up. When we first got Sophos installed it changed the amount of data our incrementals were backing up to almost fulls everynight. There is a regedit that can be done with...
Hello,
Run a Storage Policy report from your reports. It'll give you the Dedup numbers for each Storage Policy.
Size of Application, Space Occupied on Media and Space SAved along with your Percentage saved. You can pretty much confirm roughly the space on your drives to the Space Occupied On...
We've been working on deploying Sophos in an large existing domain with Commvault 8.0. Our issue is that overnight the diffential backups increased 1000% per server. 3-4 TB amounts of data rather than 400-600GB per night.
Sophos is configured to scan every night at 3AM with on-access set to...
Anyone using IBM ULTRIUM-TD4 SCSI tape drives. The issue is compression on the tape.
Our library is a DL6020 from Dell. IBM is the drive mfg however we're unable to find drivers for 2008 x64. The one link on IBM's site is for 2008 x64 is for AMD64 and E64. We have Intel Xeon processor. We...
Before you do this have as good a backup as you can, for virtual servers export and copy it off to another server for protection. Disclaimer: This worked for me on 4 servers. I have 8 more to go. This may or may not work for your situation but it points you in the direction for the fix...
Mr Fokker,
We had a server fail after a power surge that took the Perc controller out. After replacement we installed the basic OS and 1 note here, the restore has to be done to the same SP level OS as the backup was done at. We loaded the OS 2003 then to SP2. Did the restore to C:Drive with...
Great Info, Are your ML2000/ML4000 tape libraries doing compression on your LTO-4's or are you getting native <800GB tape compression. We have an ML6020 and are not getting any compression.
Thanks in advance

OK, Anyone following this thread. The issue comes to the disk configuration. Here's what I found out. It is the disk configuration. We rebuilt that server with a straight 2008 x64 OS install. 78MB EISA and used the remaining 67GB unallocated space for the OS. Completed the install with no...
Hey there Mr Fokker,
Yep seen this on our Aux copy also. We had a CommVault Engineer here last week completing our configuration. The Failed to Read chunk is an error that comes up after the tape is cycled out of teh drive. Ouor configuration is Disk to Disk to Tape. Our tape is a ML6020...
I'll check the backup logs for the System State. For the OS's they're all 2008 Enterprise X64. We're looking at the original disk configuration as the issue. The servers are all Dell PE with M600 blades and 6850s. The drives came configured with 78MB EISA, D:OS 2GB and the remaining 60+GB to...
Thanks Psy053,
Did that. The default subclient works great without the system state check box BUT... The system state subclient fails every time on every client that I had the original problem. The issue then is no System State, no good recovery plan except complete rebuild. Not a great a...
d3h614,
We are using DeDup within CV8.0. Disk to Disk to Tape. For the Dedup with about 38 servers after the initial fulls and then about 2 weeks with incremental and syn fulls we got a 79 to 89% reduction. We have a new CV system ie 3 weeks old DC, File and APP servers with about 10TB which...
