    is their a way of telling, or a terminal command to run to see if time machine has successfully ran a backup whilst asleep ?

    and also, my mac mini wakes every hour for some reason, does the mac wake up to do a TM backup ?

    many thanks

    You can check the last Time Machine backup by clicking on the Time Machine icon on the top menu bar of your screen near the clock and it will state the latest backup date and time. Alternatively, you can go into System Settings>Time Machine and find "Latest Backup".

    hello thanks for reply ...
    your right it does say when last backup was -
    but unfortunately my mini has a habit of wakin up by itself ...

    when in terminal ... and asking for wake reason log ... it says the mini wakes ever hour for some reason, usually a "rtc alarm"...

    so I don't know if the mac is wakin to do a scheduled TM backup, or wakin up for another reason :/ ...

    on a hole ... I'd like the TM to backup whilst it's in power nap... an not wake the system to do a backup ...

    thanks for reply

    Open Console app and type backup in the filter at the top and you can scroll through log entries related to TM and they will show the date/time of the backups.

    That looks like a normal log entry for a successful Time Machine backup. So if your Mini supports Powernap (list here) and you let it sleep then check the log in the morning, you will be able to see entires like this for the TM backups during sleep.

    Also, just a note: "Power Nap" is actually waking up the computer. Those hourly entries are Power Nap, waking up to do Power Nap tasks.

    The computer can't do anything while actually "asleep." It must wake up to do anything. Apple has a special "not fully awake" mode they call Power Nap that wakes up the essential parts, without turning on the display output. But it is still most certainly "awake" by any reasonable definition.
