Restic-Backup

Shell scripts to automate backup of a folder to a Backblaze B2 bucket or another local folder using Restic.

Environment Variables

Copy or rename the vars.template.sh file to vars.sh, then fill in the empty variables:

  • B2_ACCOUNT_ID - Application Key ID for a BackBlaze B2 account.
  • B2_ACCOUNT_KEY - Application Key for the above Key ID.
  • RESTIC_PASSWORD - Password to the encrypted Restic repo (if running for the first time, set this to the desired password). If this is empty, you will be asked for a password when running commands.
  • TARGETBUCKET - B2 Bucket name where the Restic repo should be. If this is left empty, the Restic repo is assumed to be a local folder at REMOTEPATH.
  • LOCALPATH - Path to the local folder to be backed up.
  • REMOTEPATH - Remote path for where the backup should be stored in the Restic repo on B2.
  • RETENTIONPOLICY - Options to use when running forget the command.

You can place vars.sh at an alternative path and provide it as the first argument to the script.

Actions

  • Backup - Backs up the folder to the Restic repo on BackBlaze, according to the configuration in vars.sh. Creates a backup if one does not exist, else updates the existing backup.
  • Forget - Runs a forget command to mark certain snapshots for deletion. Uses the RETENTIONPOLICY from vars.sh to target the snapshots to be deleted.
  • Prune - Runs a prune command to actually delete all snapshots that are marked for deletion, as well as any invalid snapshots.
  • List Backup Snapshots - Lists all backup snapshots for the configured Restic repo on BackBlaze.
  • Check Backup Integrity - Checks to see if the currently backed up snapshots are valid.
  • Mount - Mounts the repo to ~/resticBackup. This can be used to restore data.
  • Freeform - Allows you to run any other Restic command, such as prune, using the configuration in vars.sh.

Usage

Run main.sh and pick a command.
