Source 1 — Live Xero
Your active organization. Anything that corrupts the live record corrupts this source.
From Xero's Terms of Use
"If your data is lost or corrupted, our liability is limited to taking reasonable steps to try to recover the data from our own available backups."
Translation: if their backup is incomplete, stale, or unavailable — you're on your own.
Compromised Xero credentials let attackers delete or modify records. Xero won't roll back the damage — they'll restore from their own backup if available, but transactions you posted in the meantime are gone. Independent backups lock attackers out of the recovery loop.
A bookkeeper exits, an admin reassigns roles, an automation is misconfigured — and historical data is overwritten or deleted. Xero's recovery isn't designed for human error at the customer-account level.
Bank feeds drop. Reconciliations re-run. Bulk imports overlap. Each of these creates the kind of silent data drift that's invisible until you try to close the month. A point-in-time snapshot lets you compare and revert.
Xero outages happen, billing disputes happen, subscriptions get cancelled. None of these are 'data loss' events — but in each one, the practical effect is the same: you can't reach your records when you need them.
Most accounting-firm cyber policies require three sources: the live system, a provider-managed backup, and an independent third-party backup. Xero counts as one provider — they hold both your live data and their internal backup. The third source is on you.
Each jurisdiction has its own rules for where accounting data must live and how long it must be retained. Xero stores data globally, in regions of their choosing. WOW lets you pin your backup to the country your regulator expects.
