lionbackup wizard

The lionbackup wizard is the graphical interface to the lionbackup client. It creates configurations, starts backups, restores backups and shows the log. The actual work — compressing, encrypting, transferring — is done by the client.

Set up​

On first start, an assistant guides you to your first configuration:

  1. Provide client — the wizard downloads the client or uses an existing one.
  2. Project & access — enter the access token from the portal; the wizard resolves the project and storage zone from it.
  3. What to back up? — choose files and folders.
  4. Encryption — generate a key pair or choose an existing public key.
  5. Directories and Fine-tuning — the defaults fit in most cases.
Keep the private key safe

The wizard does not store the private key (.key). Keep it separate from the backed-up data — without it no restore is possible.

You create further configurations via the Active configuration tile at the bottom of the sidebar; that is also where you switch between them.

Back up​

Under Back up, the wizard starts a run with the active configuration and shows the progress; Cancel stops it. You change sources, compression and further settings under Configuration. There, Test methods measures ZSTD, GZIP and LZMA2 on your own data and recommends one.

Restore​

A restore needs a token that may read: a read token (portal → Tokens) or a download token, which the portal creates when you download a backup. A download token is valid for a single download. The backup configuration's token may only back up.

  1. Enter the token and Check — the wizard lists the project's backups.
  2. Choose the backup, the private key and the target folder.
  3. Restore backup.

Each backup goes into its own subfolder, named after the archive and the time of the backup; existing files are left untouched. If the key does not match, the downloaded archive stays in place, and with the right key the restore continues without a second download.

Instead of typing in the token, you can open the restore config that the portal offers with Save as file.

Help with problems​

About & updates → Create a diagnostics bundle saves a text file for support: the wizard and client versions, the active configuration (without the token), the runs of this session and the log files. Attach it to your request.
