Storage & backup

Map disks and mounts, understand filesystems, and plan a verifiable restore.

Identify the device, filesystem, mount, and backup destination before acting. A mounted disk is not a backup; a completed backup still needs a restore check. Keep diagnostic reads separate from formatting, repair, and deletion.

Where to start

Begin with lsblk and findmnt to map the system. Read filesystem-specific guidance before repairs. Use restic or Borg's restoration documentation to test recovering representative files to a separate directory.

How this library is selected

References are selected for a concrete operational task, with preference for project and distribution documentation. Annotations describe when to use a source; version labels make its scope explicit.

Selection reviewed means the destination, subject, and version scope were checked. It is not a claim that every upstream command has been tested. Original guides identify their own test environment. Platform filters also include references that apply across distributions.
