$ tmutil snapshot で作るAPFSのSnapshot / Local Time Machine snapshot はTimeMachine起動すると/Volumes下にマウントするみたい
なかなかカシコイ…但し, snapshot( tmutil snapshot ) と Local Time Mahine snapshot( tmutil localsnapshot )は区別されていないみたい
ref.
コレ手動でやるなら
$ tmutil mountlocalSnapshots /
Mounted local snapshots: (
"/Volumes/com.apple.TimeMachine.localsnapshots/Backups.backupdb/hoge/2018-11-02-022235/hogehoge",
"/Volumes/com.apple.TimeMachine.localsnapshots/Backups.backupdb/hoge/2018-10-31-215500/hogehoge"
)
でマウント↓
$ ls -la /Volumes/ | grep com.apple.TimeMachine.localsnapshots
drwxr-xr-x+ 3 root wheel 96 11 2 02:24 com.apple.TimeMachine.localsnapshots
アンマウントは
$ tmutil unmountlocalSnapshots /
でね..
….あとAPFS系は以下にオモシロイモノが,,,
$ ls -l /System/Library/Filesystems/apfs.fs/Contents/Resources
