A backup didn't run
When a backup set didn't run, its card in Data Backup says why — usually a condition you set, such as only on power or outside working hours, a destination that isn't connected, or a passphrase it needs. Back up now always starts one straight away.
When a backup didn't run, the set's card in Data Backup says why in a sentence. Most often it's waiting on purpose — for power, for Wi-Fi, for your working hours to end, or for the destination drive to be connected — or it needs a passphrase from you. Back up now starts a backup straight away whatever the conditions, so it's also the quickest test.
What you might see on the card
| Status or message | What it means |
|---|---|
| Waiting for power — you asked for backups to run only when plugged in. | Plug your Mac in, or change the condition. |
| Waiting for Wi-Fi — you asked for backups to stay off hotspots. | You're on a personal hotspot. It runs once you're back on Wi-Fi. |
| Waiting until … — you asked for backups to stay out of these hours. | It's inside the hours you set aside. |
| Paused while your Mac is busy — … It picks up where it left off on its own. | Storage Studio stepped aside while you needed the Mac. |
| Waiting for a faster connection — the upload to … is running at about …, which is too slow to finish a backup. | Automatic cloud backups wait for a better connection. Back up now still works. |
| Set a backup passphrase for “…” before its first cloud backup. | Click Set passphrase…. |
| That backup passphrase didn't match. | Click Re-enter passphrase…. Automatic runs stop trying until you do. |
| Couldn't reach the backup destination … Connect the drive or check your network. | The drive isn't connected, or the network is down. |
| The last backup didn't finish — Storage Studio closed while it was running. | It picks up where it left off; use Back up now when you're ready. |
| Not backed up | It hasn't run yet — check it has folders to back up and a trigger. |
Likely causes
- A condition you set is holding it — The Mac is plugged in, Not on a personal hotspot, or Stay out of my working hours.
- The trigger is Only when I ask — "Nothing happens until you press Back up now."
- The destination isn't there. For an automatic run, an unreachable drive doesn't turn the card red; it waits quietly and tries again once the drive is back.
- A passphrase is missing or wrong.
- The Mac was asleep or Storage Studio wasn't running at the scheduled time.

How to fix it
- Open Data Backup (Versioned)… from the More menu and find the set.
- Read the sentence on its card and act on it — plug in, connect the drive, or enter the passphrase.
- Click Change… to review When to back up and its Only when conditions if they no longer suit you.
- Click Back up now to run it straight away. A manual backup ignores the power, hotspot and working-hours conditions.
Good to know
- Missed times don't pile up. If your Mac was asleep at one or more scheduled times, they're combined into a single backup when it can next run, rather than several back to back.
- Battery. While a backup runs, Storage Studio keeps the Mac awake if it's plugged in or the battery is above 30%. Below that, it lets the Mac sleep and the backup carries on later from where it stopped. With the lid closed on battery, macOS sleeps regardless.
