Back Up and Restore Using the Network File System Server

You can back up the Virtual Appliance data to the Network File System (NFS) server. Follow these steps to back up the Virtual Appliance data:

Set Up the NFS Server

This section considers AlmaLinux OS as an example OS to install the NFS server. Follow these steps to install and configure the NFS server:

1. Run the following commands to install the NFS server.
   

   dnf install nfs-utils
   mkdir -p /mnt/nfs_share
   chown nobody:nobody /mnt/nfs_share
   chmod 777 -R /mnt/nfs_share/

   CODE
2. Configure the NFS exports.
   

   /mnt/nfs_share 10.0.203.0/24(rw,sync,no_subtree_check,no_root_squash)
   /mnt/nfs_share 10.0.202.0/24(rw,sync,no_subtree_check,no_root_squash)

   CODE
3. Restart the NFS server:
   

   systemctl restart nfs-server

   CODE
4. Verify the NFS server status:
   

   systemctl status nfs-server

   CODE

Configure the NFS Parameters on Virtual Appliance

Edit the globals.yaml.gotmpl file with the NFS server details:

# NFS parameters
nfs:
  server: 10.0.203.142
  path: /mnt/nfs_share

Configure the NFS Server on the globals.yaml.gotmpl File

1. Create a repository to back up the data in the NFS server.
   
   

   You can create repository only for the Elasticsearch backup. By default, the globals.yaml.gotmpl file uses the repo3 repository for MySQL and PostgreSQL. 

   
   

   appdcli run es_backup create-fs-repo virtual-appliance-repo-nfs

   CODE
2. Enable the fs section for datastores to back up using the NFS server. See globals.yaml.gotmpl file.
   
   # Backup config for datastores
   backup:
     elasticsearch:
       fs:
         enabled: true
         storage: 5Gi

   CODE

   
   

   # Backup config for datastores
   backup:
     postgresql:
       fs:
         enabled: true
         repoName: repo3
         storage: 5Gipg-

   CODE

   
   

   
   

   # Backup config for datastores
   backup:  
     mysql:
       fs:
         enabled: true
         repoName: repo3
         storage: 5Gi

   CODE

   
   

   
   

Back Up the Virtual Appliance Data in the NFS Server

Snapshots capture the state of the datastore and can be used to restore data. You can store multiple snapshots in a single repository. The following commands stores the snapshots in the virtual-appliance-repo-nfs repository.

Create a snapshot for each datastore:

appdcli run es_backup create-snapshot <repo-name> <snapshot-name>

appdcli run es_backup create-snapshot virtual-appliance-repo-nfs es-snapshot

appdcli run pg_backup create-snapshot <repo-name> <snapshot-name>

appdcli run pg_backup create-snapshot repo3 pg-snapshot

appdcli run mysql_backup create-snapshot <repo-name> <snapshot-name>

appdcli run mysql_backup create-snapshot repo3 mysql-snapshot

Restore Snapshots from the NFS server

Use the snapshots that you have stored in NFS to restore the datastores.

1. List the snapshots in the repository:
   
   appdcli run es_backup list-snapshot <repo-name>

   CODE

   Example

   appdcli run es_backup list-snapshot virtual-appliance-repo-nfs 

   CODE

   appdcli run pg_backup list-snapshot <repo-name>

   CODE

   Example

   appdcli run pg_backup list-snapshot repo3

   CODE

   
   

   appdcli run mysql_backup list-snapshot <repo-name>

   CODE

   Example

   appdcli run mysql_backup list-snapshot repo3

   CODE

   
   

2. Restore the datastore by one of the snapshots:
   
   appdcli run es_backup restore-snapshot <repo-name> <snapshot-name>

   CODE

   Example

   appdcli run es_backup restore-snapshot virtual-appliance-repo-nfs es_snapshot

   CODE

   appdcli run pg_backup restore-snapshot <repo-name>

   CODE

   Example

   appdcli run pg_backup restore-snapshot repo3 pg_snapshot

   CODE

   
   

   appdcli run mysql_backup restore-snapshot <repo-name>

   CODE

   Example

   appdcli run mysql_backup restore-snapshot repo3 mysql_snapshot

   CODE

   
   

Delete the Snapshots from the NFS Server

If you no longer require the snapshot, you can delete the snapshot from NFS.

appdcli run es_backup delete-snapshot <repo-name> <snapshot-name>

appdcli run es_backup delete-snapshot virtual-appliance-repo-nfs es_snapshot

appdcli run pg_backup delete-snapshot <repo-name>

appdcli run pg_backup delete-snapshot repo3 pg_snapshot

appdcli run mysql_backup delete-snapshot <repo-name>

appdcli run mysql_backup delete-snapshot repo3 mysql_snapshot
