Backups & restore points · When backups run
Can I stop backups from using my phone's hotspot data?
Short answer: Yes. Turn on Not on a personal hotspot under Only when in the set's Change… popover. Cloud backups then wait while you're tethered and resume on a normal network.
Yes. In the set's Change… popover, under Only when, turn on Not on a personal hotspot. It applies to cloud destinations, so a backup never eats a phone's data allowance.
While you're tethered, the card reads "Waiting for Wi-Fi — you asked for backups to stay off hotspots." The backup carries on once you're back on a normal network.
