Greetings Nethserver community! I am new to this community and to Nethserver. I’ve researched many turnkey servers out there and I am greatly impressed with Nethserver. With that said, I’ve decided that Nethserver would be used as my turnkey server.
I am hoping your kind community can help me here. I am using nethserver as a file server joined to an Active Directory domain served by a dedicated Samba 4 AD that is not a nethserver. My issue is with data backups. My nethserver is a guest in KVM virtual machine. I have a USB drive attached. However I have the USB drive attached as local storage for the nethserver vm so nethserver see it as a mounted hard drive. The problem is that the data backup wizard will not let me select a local disk without it being explicitly a detected USB device. Understandably, I then tried to pass through the USB device using Virt-manager which failed. So my only option is to use the USB storage a mounted hard drive to the neth VM. Is there a way I can edit/modify the config file that will allow me to have backups to a mounted local location? Thanks in advance.
I m not a wizard of file systems. Personally I prefer XFS for its management of very large number of inodes. I ran into this problem with BackupPC which uses a very large amount of inodes. Also I like its management of ACL.
In your case of backuping of NethServer, that is not so important as there isn’t so many files the backup will create. You can specify a large block size to minimize the amount of space the table will take to store the inodes.
To take a step back for clarity, here is my setup…
KVM Host.
Storage attached to Host Server:
Multiple hard disks, one being a USB hard disk.
KVM - Guests
Samba4 AD
Nethserver - Functions on the domain as file server, profiles, user data, etc…
USB hard disk is passed through setup as raw/virtio (/dev/vdc). Mounted as /backup
Problem:
Data Backup module
NFS:
Currently there are no wizards that allow me to access the mount at “/backup”. Using NFS, I must supply a “Host”. I tried to use “localhost”, and the name of my Nethserver. That wouldn’t take.
Local Storage/USB:
Even though my USB is mounted as a hard disk (/dev/vdc), it doesn’t show in the drop list. There is not a free form text area to supply the path to the mount.
All other wizards are specific to remote which in this case wouldn’t apply.
So the way I see it, there must be a configuration file associated with the data backup module that I could maybe edit to enter an explicit path to the backup folder. Any other suggestions would be appreciated. Thanks again.

From my old Virtual Machine from VirtualBox:
To try a backup from the command line:
# backup-data -b backup-data
For the USB, it should works Destination USB Disk
Select the backup destination to a USB drive. The USB disk must be formatted with a compatible file system (ext2/3/4 or FAT, NTFS not supported) and a label configured.
Filesystem label: lists connected USB disks. If the disk is mounted, it is marked with an “M”.
I remember that I used the above links for the NFS configuration.
