Backup with VSS plug-in
Hi,
I've some questions regarding the dataset's plug-in in Avamar 6.1
I have to backup some windows R2 servers with a need of restoring the full server in case of losing it after any event
For the moment my dataset is configured with both File System and VSS plugin
I can recover files in my local drives indivually, and I can also recover the system state
But when I'm looking at the volume taken by each backup I see that the VSS backup is larger than de File System
So I've thaught that only the VSS backup would be needed in my case
My questions are :
- do I need to do a File System backup since I make a VSS backup ?
- do VSS backup permits to recover my server in full, with it's registry, local drives etc ?
- what is the best practice for dataset if I want to be sure to recover my server with all it's programs, configurations, and files (except databases of courses)
Thx !

While the VSS system state plug-in and filesystem plug-in will have some overlap, any data that appears in both backups will be de-duplicated, so it will not consume additional space on the server. The vast majority of client systems complete backups within 1-2 hours (many much faster) so the runtime required to process the files twice is not normally an issue.

ianderson said is correct.
You can to refer "EMC Avamar 6.1 for Windows Server User Guide" to complete these operations.

Thank you so much you both !
Everything is clear for me now
I don't know which policy I'll apply, my goal is to bring down at maximum the volume of my backup (question of cost obviously),but you helped me a lot.
Best regards

Are they virtual servers you are trying to backup? We used to run VSS and Data backups as described above but now just run VM snapshot backups which covers everything in a single backup.

Yes it's VM hosted by a vmware server
I've no access to the host but only to my VM's where the Avamar client is installed
I don't know which plug in you're talking about : maybe Windows VMware Image ?
And what about the volume used by these backups : do they use differential backup or are they one full block ?
Thx

Have a look at the "EMC Avamar 6.1 for VMWare User Guide" document on powerlink as it explains VM backup fully.
The basics are: you do need to deploy a special 'Proxy' VM (template can be downloaded form your Avamar node) that transfers the VM snapshots that vSphere generates into Avamar. The Avamar node needs to be connected to vCenter with an account that has the correct rights to vSphere.
It is possible to do CBT or Changed Block Tracking VM backups so that only the changed blocks of the VM snapshot are backed up so that is sort of like a differential I guess.

Well since my Avamar solution is provided by the hoster, I've no controll on its configuration or even adding any options.
I've to use what they give me, so I think that this solution cannot be used in my case.
The other point is that my provider tried to restore one of my VSS backup and it didn't work out.
For the moment I'm waiting for them to be capable of doing a proper restore before changing anything in my backup plan.
