Important notes

/!\ If you decided to select an encryption method and set a password, keep in mind your backups will be irretrievable if you loose this password!

/!\ Never delete your backup configuration after the first backup started running. Deletinc a configuration deletes the database keeping track of files in backup archives makes restoring files very difficult. If you want to delete a backup configuration which contains backups, export it first!
