Filerestore from a Novell /NSS Volume Opentext OES Server based on SUSE SLES

Single file restore is only supported for a subset of filesystems. You might want to use
Code:
proxmox-backup-client map <snapshot> <archive-name>
to map the raw disk images to a loop device on a the host were you would like to access the contents from and mount via loop device (NSS pool first, then NSS volume I assume).
