I love the fact that VMware is providing VDR as part of the vSphere package. It's definitely a step in the right direction, albeit I'm still inclined to think this software hasn't been put through the ringer in terms of proper QA. I'm just trying to put out a feeler to see how many others have experienced some of the same issues I'm having.
To start, I'm backing up my VMs via a network share on a standalone Windows 2003 server that has a NAS attached to it.
Some of the issues I've noticed:
1) Backups take an inordinate amount of time. I can understand the first backup, but my VMs don't change very much from day to day. Most of the data being manipulated is located on RDMs are these are backed up using Tivoli, not VDR (I use VDR solely for the OS partitions). Each partition is approximately 25GB, there are 15 VMs and my backup window (10pm - 6pm) isn't sufficient to complete the process.
2) Integrity checks for the backups are taking a crazy amount of time and will usually stop due to my window being closed (see point #1)
3) I'm getting inconsistent "failures" for certain VMs (the report will simply state that a VM failed to backup, not much else). It also varies per night and not always the same VMs (not exactly sure if this is related to #1 where the window is closing while VDR is executing)
4) I had the most difficult time setting up the remote share from the VDR appliance in vSphere. The username and password would never be accepted (even though if I tried the same share with the same user/pass on a Windows machine, it would work fine). I finally narrowed down the problem to the simple fact that the VDR appliance can't handle passwords that have special characters in them (this password had an "@" and a ","). Looking at the console while attempting to mount the share would spit out a CIFS error -22. Changing the password to include only numbers and letters was sufficient to work around this issue.
5) Snapshots not being created for no apparent reason and thus failing the VDR process. I'm fully able to do a manual snapshot with or without the memory state, so I'm not sure why VDR can't do it. This issue is very intermittent. I had it often when I first setup VDR, but now it only happens every so often (without any type of consistency).
I think that's all I can think about for now..
