isoLayer (Synthetic)


You need a NFS server with storage with XFS filesystem to properly configure isoLayer Backup Destination in Storware Backup & Recovery.


  1. 1.
    On NFS server we need to create NFS share, for example:
    mkdir /NFS
  2. 2.
    Edit file /etc/exports to add access to this share:
    /NFS SBR_NODE_IP(rw,sync,no_all_squash,no_root_squash)
    Where SBR_NODE_IP is IP of Storware Backup & Recovery Node, which will have access to this share
  3. 3.
    Generate new SSH keys, without any password:
    Generating public/private rsa key pair.
    Enter file in which to save the key (/root/.ssh/id_rsa):
    Enter passphrase (empty for no passphrase):
    Enter same passphrase again:
    Your identification has been saved in /root/.ssh/id_rsa.
    Your public key has been saved in /root/.ssh/
    The key fingerprint is:
    SHA256:H2NJwORiG3oJDm78sKEx4EuOzIm13vUsJ6NfMOPVgt0 root@vpro43-vmware
    The key's randomart image is:
    +---[RSA 3072]----+
    | oo |
    | ... |
    |. . . + . . |
    |oo o + B + . |
    |ooB o O S E |
    |B*o* o = + o |
    |+*o . o . . |
    | . . .++. |
    | . oo.=o |
  4. 4.
    Add new public key to /root/.ssh/authorized_keys file
    cat /root/.ssh/ > /root/.ssh/authotized_keys
  5. 5.
    Copy generated private key (id_rsa) to Storware Backup & Recovery Node host
    scp /root/.ssh/id_rsa root@SBR_NODE_IP:/opt/vprotect/.ssh/
  6. 6.
    SSH to Storware Backup & Recovery Node and change owner of this file:
    chown vprotect:vprotect /opt/vprotect/.ssh/id_rsa
  7. 7.
    Connect from Storware Backup & Recovery Node to NFSs:
    ssh -i /opt/vprotect/.ssh/id_rsa root@NFSs
    accept new fingerprint and exit from remote session
  8. 8.
    Copy last line from /root/.ssh/known_hosts file into /opt/vprotect/.ssh/known_hosts file
  9. 9.
    Configure isoLayer connection. Edit /opt/vprotect/scripts/isoLayer/config file:
    vi /opt/vprotect/scripts/isoLayer/config)
    NFS_HOST - IP address of NFS server
    NFS_HOST_PATTERN - IP address (CIDR) of NFS server, for example:
    NFS_ROOT - NFS server share path, where we want to store our backups, for example /NFS/backup

Creating isoLayer backup destination

  1. 1.
    Login into Storware Backup & Recovery UI.
  2. 2.
    From menu on the left, select Backup Destinations -> File System.
  3. 3.
    On the right, click Create Backup Destination button and choose isoLayer (Synthetic).
  4. 4.
    In new window:
    • type name for the backup destination
    • select Node Configurations
    • provide backup destination path – this is place, where from Storware Backup & Recovery Node perspective, isoLayer will be temporary mount share from NFS server
    • Check if pre and post scripts are active, and correct paths are provided like in example:
    • Click Save button
  5. 5.
    Now you can use this isoLayer connection to store your backup.
