ACSP Data Management and Backups 4

Question 1

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

Accepted Answer

fsck -fy /dev/disk1s1

Answer

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

Question 2

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

Accepted Answer

Sparse bundle disk image (.sparsebundle)

Answer

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

Question 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?

Accepted Answer

iCloud Drive version history

Answer

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

Question 4

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

Accepted Answer

The local snapshot is deleted after the backup completes

Answer

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.

Question 5

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

Accepted Answer

When initially selecting the backup disk in Time Machine settings

Answer

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