BackupTrust Pro 2.1 (21) — Testing

Encryption test build, Pro only.

Destinations can now be encrypted. Create a key in Settings > Encryption, save its
recovery key file, then choose that key under a destination in the plan editor.
Files written there become .aea archives that only that recovery file can open.

BackupTrust keeps only the public half of the key, so a scheduled run needs no
password and this Mac cannot read its own backups. The recovery key file is the
only way to decrypt them - keep it somewhere separate from the backup.

Each encrypted destination carries restore instructions and a restore script that
needs only the aea tool built into macOS. Test a Restore decrypts a sample to
prove a backup opens.
