Read the first 7 Data Management and Backups flashcards as text

  1. A user's Mac has a corrupted APFS volume. Which Terminal command can be used to verify and repair the file system?

    Answer: fsck -fy /dev/disk1s1

    fsck (file system consistency check) with -fy flags forces a check and automatically repairs the APFS or HFS+ volume when run from Recovery Mode.

  2. When using Time Machine with a network share (SMB), what file format does macOS use to store the backup?

    Answer: Sparse bundle disk image (.sparsebundle)

    Time Machine stores network backups as a sparse bundle disk image (.sparsebundle), which allows efficient incremental updates over the network.

  3. A user accidentally deleted files from their Mac and emptied the Trash. Time Machine is not configured. Which macOS feature might still allow file recovery?

    Answer: iCloud Drive version history

    iCloud Drive keeps version history and recently deleted files for up to 30 days, providing a recovery option when Time Machine is unavailable.

  4. What happens to APFS snapshots when a Time Machine backup is successfully completed on an APFS volume?

    Answer: The local snapshot is deleted after the backup completes

    macOS creates a local APFS snapshot before backing up, and once the Time Machine backup to the external destination completes successfully, the local snapshot is removed.

  5. A company requires that all employee Mac backups be encrypted. When configuring Time Machine, at which point can encryption be enabled?

    Answer: When initially selecting the backup disk in Time Machine settings

    Time Machine offers an option to encrypt the backup disk when you first select it as the backup destination in System Settings.

  6. Which utility in macOS Recovery can be used to restore an entire Mac from a Time Machine backup?

    Answer: Restore from Time Machine Backup

    macOS Recovery includes a 'Restore from Time Machine Backup' option that allows full system restoration directly from a Time Machine backup.

  7. A user has an APFS volume with snapshots enabled. How can they browse and restore files from a local APFS snapshot without an external backup drive?

    Answer: Open Time Machine; it can browse local APFS snapshots

    The Time Machine interface can browse local APFS snapshots even without a connected external backup drive, allowing file-level restoration.
