    An off-site copy in your own bucket

Each location holds a complete copy of your saved mail. Horcrux updates those copies when it backs up the account.

See when each inbox was last backed up.

Set a schedule for each account and let Horcrux run in the background. Follow the current mailbox as it saves, then open Jobs to see when the backup finished and whether verification passed.

Backup History keeps dated snapshots. Pick a date before a message was deleted, search the saved mailbox, and open its attachments. You can do this offline with a local copy.

When one copy needs repair.

Verification checks the messages in a saved backup. If a drive loses a message, Horcrux can retrieve it from a healthy copy on another drive or server.

How recovery works

Take your mail to another account.

Restore a dated backup to an inbox, move mail between providers, or export a mailbox as an MBOX file. Choose the folders and dates you need before copying.
