Backup2Azure

Small script to upload a set of files to Azure Blob Storage (using the Azure CLI). Storage tier can be configured. Tested with Debian and Ubuntu

By default, this will look for Proxmox LXC/VM backups (vzdump*.zst) and PVE host config backups (pve-host*.zst) and upload to your Azure storage container every 3 months. It will not overwrite already uploaded backups. Setting up a retention policy in your container is recommended (eg. 1 year)

Requirements

• An active Azure account
  • Create a storage account
    • Create a container (where the files will be uploaded)

Setup

1. Download and extract the repo
2. Run install_deps.sh
3. Run install.sh
4. Configure /etc/Backup2Azure/backup2azure.conf

• account_name --> Azure storage account name
• container_name --> Azure storage container name
• search_dir --> local directory containing the files to upload (can be a mounted directory)
• tier --> Azure storage tier to use (ARCHIVE, COLD or HOT)

6. Run CreateServicePrincipale.sh <YourAzureSubscriptionId> <YourAzureStorageResourceGroup> to create a service principal that the script will use to authenticate
7. Add the service principal details to /etc/Backup2Azure/backup2azure.conf

• sp_app_id --> Service principal application ID
• sp_password --> Service principal password
• sp_tenant_id --> Service principal tenant ID
