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:

  vstor partner show
  #ID                               | MGMT ADDRESS | API PORT | SSH PORT
  #55cd380b7dc848bbb439bfd444bc1799 | 10.10.10.2   | 8900     | 22

• 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:

   2018-05-04 15:31:39.133  INFO
