Catalogic Software vStor

vPlus 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. vPlus accesses vStor Servers using SSH public key authentication - first generate the key:

    sudo -u vprotect ssh-keygen

  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

    Example:

    sudo -u vprotect ssh -o HostKeyAlgorithms=ssh-rsa [email protected]

#The authenticity of host '10.10.10.1 (10.10.10.1)' 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 '10.10.10.1' (RSA) to the list of known hosts.

  3. Copy the key to each vStor Server:

    sudo -u vprotect ssh-copy-id [email protected]

#/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/opt/vprotect/.ssh/id_rsa.pub"
#/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
#[email protected]'s password:
#_
#Number of key(s) added: 1
#_
#Now try logging into the machine, with:   "ssh '[email protected]'"
#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:

  • If a secondary server is not provided, vPlus 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:
