# How does restore work?

Backed-up emails are pushed to the IMAP server.
If there are clashes, folders are renamed.

# What are all these 'INBOX.12345' files?

If, when the backup is launched, the IMAP server contains a folder with
the same name, but different history to the local backup, the local
emails cannot simply be added to the existing folder.

In this case, a numeric suffix is added to the **local** folder,
before it is restored.

In this way, old and new emails are kept separate.

# Will my email get overwritten?

No.

Emails are identified by folder and a specific email id. Any email that
is already on the server is skipped.

## How do I restore to a different service?

1. Run setup and add the new server, (but don't run any backups),
2. Rename of the existing backup directory to match the new email address,
3. Run the restore.
