Backups & restore points · When backups run
Why doesn't my backup start the instant I save a file?
Short answer: As things change waits for a short quiet moment after your edits, so a burst of saves becomes one version. Press Back up now for an immediate version, or add a daily version for constantly busy folders.
With As things change, Storage Studio waits for a short quiet moment after your changes before it backs up. That way a burst of saves — an app writing a file several times, or you saving every few seconds — becomes one tidy version instead of dozens.
If a folder changes so constantly that the quiet moment never comes, turn on Also make one version a day in the set's Change… popover. And if you want a version right now, press Back up now.
