Hi Everyone,

I have recently found that we have various disks with corrupt data, all our backups consist of a policy where the primary copies are kept permanently in the overland storage and secondary copies are shipped off. Is there a way to run a verify on all the tapes currently in the overland storage or all primary tapes. I am not sure if a batch job can be run or if there is a facility within Commvault to do this.

many thanks,


- Josh

Josh,
       CommVault does have the facility to do this - I beileve that it is a licensed feature called Data Verification. To verify, you run the data verification job against all, or specific jobs within a storage policy copy. You can check CommVaults books online for specifics for the feature

Hi Rjordine, thanks for getting back to me. I have this Data Verification tab when choosing the properties of the storage policy, but how do I force a verify on all tapes currently in the library, more importantly the old archived tapes.

Josh - to do what you want - verify all tapes, you just need to enable verification on all the copies for that library. Keep in mind that you will want to run this when your backups are NOT running as verification will mount source media into your drive(s). You also want to have ALL the tapes on hand to place into the library. I Quote below from the 6.1 Books online

To configure a storage policy copy for data verification:
1.From the right pane of the CommCell Browser, right-click the storage policy, and then click Properties.
2.From the Data Verification tab of the Copy Properties dialog box, click the All Backups option if you want all backups to be verified         during a data verification operation, or click All Full Backups if you want only full backups to be verified. You can also click the Backups On or After Date option and select a date from the Select a Date list. Only those backups that occur on or after the date you select will be verified.
3.Additionally, you can select the Verification Expires after option and choose the appropriate number of months from the list.
4.Click OK to save the changes.

To start a data verification operation:
1.From the CommCell Browser, right-click the storage policy for which you want to verify the data, click All Tasks, and then click Verify Data.
2.From the Data Verification dialog box, select either All Copies, or a select copy from the Select a Copy list.
3.Select the number of streams to verify in parallel from the Number of Streams to Copy in Parallel pane, or select Allow Maximum. You may also select Jobs to Verify if you wish to select specific jobs to verify, as well as  Configure Alert if you wish to configure a Data Verification Alert.
4.To select more advanced options, click Advanced. Select the appropriate options from the Advanced Options for Data Verification dialog box. Click OK.
5.Click OK.
