Avamar and Windows mount points

Hello folks,

How does Avamar backup mount points on a Windows server , specifically a Win2k8 cluster.  Anything special needs to be done on the client (besides running cluster wizard)

Thank you

Re: Avamar and Windows mount points

I'm not aware of any special procedure for backing up mount points. General advice for backing up clusters -- be sure to back up local resources using the agent on the physical node and cluster resources using the cluster agent.

Re: Avamar and Windows mount points

Ian,

does it backup one mount point at a time ?

Re: Avamar and Windows mount points

As far as I know. I haven't tested it but I don't believe the client treats mount points differently from any other volume.

Re: Avamar and Windows mount points

I have added SAN drives to the exclude list on each physical node yet the client is still trying to back them up ?

Re: Re: Avamar and Windows mount points

You can't exclude a volume from VSS Snapshots using --exclude. There is an advanced dataset option for the Windows File System plug-in that controls VSS excludes:

Untitled.png

The "Freeze exclude volumes" field is a comma-separated list of volumes, e.g.:

C:\,D:\

The internal documentation for "Freeze exclude devices" is a little sparse but it looks to be a comma separated list of devices in the form "\Device\Something" with support for the * wildcard.

Make sure you have the "Show Advanced Options" checkbox checked or the freeze exclude options won't show up. Also, this probably doesn't need to be said but I'd recommend against modifying advanced options unless you know exactly what they do (and I'd be happy to answer any specific questions).

Re: Re: Avamar and Windows mount points

Ian,

yes, i did notice that even though it appeared as all volumes got "snapshotted" it actually did skip E:\, F:\ and W:\

Here is my current configuration:

Two node Win2k8 R2 cluster, each node has a C:\ and a D:\ local drive.  For the individual physical nodes i created avtar.cmd file and added E:\, F:\ and W:\ to the exclude list. For the "cluster" instance i created a brand new dataset and added C:\ and D:\ to the dataset exclude list. I then used this dataset for the cluster instance (modified client settings and set to "override group dataset).  I only have one cluster in the environment so i did not want to create yet another policy group.

So now exclusion is handled using avamar server dataset for the "cluster" instance, and local avtar.cmd for the physical hosts. Can i add "freeze exclude devices" to avtar.cmd and what is the difference between freezing volumes versus freezing devices.

Thank you very much, looking forward to your feedback.

Re: Re: Re: Avamar and Windows mount points

Just about anything you can add to a dataset can be added to avtar.cmd. I don't foresee any problems with adding freeze excludes to avtar.cmd. The flags will look like:

--freezeexcludevolume=E:\,F:\

--freezeexcludedevice=\Device\HardDisk1

Excluding by volume is probably easier because you can usually identify the volumes by drive letter. When you're excluding by device, you need to know the Windows device path. If there are multiple volumes on one device, excluding the device will exclude all the volumes. This is a "six of one, half dozen of the other" configuration. Use whichever approach you find easier in your environment.

My pleasure!

Re: Re: Re: Avamar and Windows mount points

Is this still the only way to handle multiple concurrent backups (7.0 SP1) ?. With 5 x 10TB mount points running one mount point at a time will take ages to complete.

Change Number of Streams Running Per Client

Thank you
