How to handle VMware Data Recovery?

Some time ago, I was asked to investigate a vSphere cluster at a customer location. It is a small sized cluster, consisting of 3 ESX hosts, approximately 20 VM’s and VMware Data Recovery as backup- and restore solution. The backup target is a dedicated NAS with 2.5 TB capacity. During the implementation, Data Recovery version 1.1 was installed. The VMware Data Recovery was configured to run several backup jobs; a daily job and a few weekly jobs for static or less important VM’s. After several months backups failed, snapshots were not removed and locking problems were reported.

First action was; updating the ESX hosts and replacing the VMware Data Recovery with the 1.2 version. During the configuration of the backup target, I noticed a warning telling me that CIFS network shares larger than 500 GB are not a good idea…

Symantec Backup Exec – Error “0xA000821 – Library Error – incompatible storage media detected in robotic library” occurs when an inventory is run against the robotic library

Last week, I encountered this situation:

• A Backup server with Windows 2003 and Symantec Backup Exec 12.5. The Daily Inventory Job has Error Reports with description: “incompatible storage media detected in robotic library”
• A Dell PowerVault TL4000 Tape library with two LTO3 drives, with a yellow “Media Alert” LED on. The Web interface showed me that some tapes has been marked “Bad”, so that explained the Media Alert.
