In case you have been living under a rock for the last couple years I should first mention that VMware does offer it’s own backup solution for vSphere. This product is called VMware Data Recovery. Think of it as a really watered down version of Veeam Backup… without the replication piece. Basically you configure a backup repository (a bulk storage area), and then configure which VM’s to backup and to which repository. Well with VDR 2.0 and vSphere 5 there are some issues, and basically I was told that they changed how they talk to CIFS shared from the VDR appliance and because of that some Repository servers are not able to keep up with the about of traffic. The downside is that because of this Integrity Checks fail to complete, and after an integrity check fails on a repository all backups to that repository are hauled.
Well after talking with VMware Tech support they recommended that I switch back to VDR 1.2.1 for the time being. So after downloading VDR 1.2.1 and configuring it I then got a new error. This time the VDR appliance failed to backup the VM because it thinks that vSphere was not taking snapshots properly. After a few more email exchanges with VMware they had me edit the /etc/resolve.conf file and add a search domain (the domain where my esx hosts live), and after doing that I was finally able to get good backups.
Once an update is released and VDR 2.0 can be used again I will update this post and also do a how-to on setting it up.
