When Avamar does a full backup of a Linux system does it pick up anything other than the files and folders? For example, a file and folder backup alone is not sufficient for a Windows system because it does not include the registry and such, therefore you have a VSS system state backup in order to do a bare metal restore. Is there an equivalent of a registry/other system files in Linux?

I'm thinking not, as the documented recovery process for a Linux filesystem is basically "install an OS then recover the files and folders from backup", but I want to be sure.

Thanks.
