Catalogic Software vStor

Storware Backup & Recovery supports Catalogic vStor Server and integrates with it with extended File System Backup Destination logic.

You can use Catalogic volumes like any other file system (mount a single volume over NFS) or you can use the scripts provided to automatically create and replicate volumes whenever vStor volume is being accessed. This documentation describes a setup with 2 vStor servers and a 1-volume-per-VM approach (with optional replication).

  1. Storware Backup & Recovery accesses vStor Servers using SSH public key authentication - first generate the key:

    [root@vProtectbuild ~]# sudo -u vprotect ssh-keygen
    Generating public/private rsa key pair.
    Enter file in which to save the key (/opt/vprotect/.ssh/id_rsa):  
    Created directory '/opt/vprotect/.ssh'.
    Enter passphrase (empty for no passphrase): 
    Enter same passphrase again: 
    Your identification has been saved in /opt/vprotect/.ssh/id_rsa.
    Your public key has been saved in /opt/vprotect/.ssh/
    The key fingerprint is:
    SHA256:xeceRtL4kq3zzQrUQH/K5SbiT/nv9QvAtBEfOxeT5us vprotect@vProtectbuild.lab.local
    The key's randomart image is:
    +---[RSA 2048]----+
    |          .. . o.|
    |         o +o ooo|
    |          *o=+=. |
    |         .o%o=o. |
    |        S =+@ o .|
    |         o *.= . |
    |          = +.. .|
    |           * +.Eo|
    |            +.++=|
  2. Add the VM fingerprint to the SSH known_hosts on the node for the primary (and optionally secondary) vStor Server:

    • It must be a known_hosts file that belongs to the vprotect user

    • The algorithm must be set to ssh-rsa

    sudo -u vprotect ssh -o HostKeyAlgorithms=ssh-rsa admin@VSTOR_HOST


    [root@vProtectbuild ~]# sudo -u vprotect ssh -o HostKeyAlgorithms=ssh-rsa admin@
    The authenticity of host ' (' can't be established.
    RSA key fingerprint is SHA256:65M/6jNBXJTFqti/798STSFeZigRzHMivDNl0t95FNI.
    RSA key fingerprint is MD5:cc:91:7d:17:8e:21:68:19:4b:c9:e4:76:bd:f5:4d:fc.
    Are you sure you want to continue connecting (yes/no)? yes
    Warning: Permanently added '' (RSA) to the list of known hosts.
  3. Copy the key to each vStor Server:

    [root@vProtectbuild ~]# sudo -u vprotect ssh-copy-id admin@
    /bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/opt/vprotect/.ssh/"
    /bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
    /bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
    admin@'s password: 
    Number of key(s) added: 1
    Now try logging into the machine, with:   "ssh 'admin@'"
    and check to make sure that only the key(s) you wanted were added.
  4. Open the "BACKUP DESTINATIONS" section on the left menu.

  5. Create a new Catalogic vStor Server Backup Destination (choose from the top-right drop-down menu).

  6. Fill in the template with your information.

  • FIRST_VS_HOST - your primary vStor Server IP/hostname

  • SECOND_VS_HOST - optional, secondary vStor Server IP/hostname, where the data will be replicated to

  • VS_PARTNER_ID - optional, secondary vStor partner ID - you can get this ID by running this command on the vStor Server shell:

    [admin@localhost ~]# vstor partner show
    ID                               | MGMT ADDRESS | API PORT | SSH PORT
    55cd380b7dc848bbb439bfd444bc1799 |   | 8900     | 22
  • If a secondary server is not provided, Storware Backup & Recovery will assume that no replication is needed.

  1. Initiate backup to test if the scripts have been executed correctly - in the vprotect_daemon.log files you should be able to see messages like this:

    2018-05-04 15:31:39.133  INFO
    [0f2b9705-61a1-44d5-876f-ac81985c4a94] Executing pre/post store command...
