Hi gurus

I am looking for some help.

Backup- AppAssure-1
V-79-57344-34086 - ADBO: Offhost backup initialization failure on: "E:".

Snapshot technology error (0xE0008526): Backup Exec could not locate a Microsoft Volume Shadow Copy Services (VSS) software or hardware snapshot technology for this job. Select a valid VSS snapshot technology for the target computer.

what I have done so far :

I have checked that MS shadow provider is install

I have checked that AOF option was check and set

I have checked that writers on remote computer are in stable state

I set ADO but uncheck the AOF

but nothing else gurus, I dont know what else should i check but I keep getting the above error, any help I would appreciate.

Thanks a bunch gurus

what is the output of vssadmin list providers on the server you are trying to backup ?

Refer . If its BE 2012 please ensure SP1 is also Installed.

What sort of disk is the E: drive?  Is it a local disk or an external disk?  How is it connected to the media server?

You got to make sure that the following conditions are met

1) the media server has a separate access to the disk to be snapped.

2) the disk configuration is supported.  Check the HCL for your version of BE.
