I don't understand why ... note that both configs won't run at the same day
(one day for backup to tape, next day a degraded backup).
When I use 'history' in amrecover I get all the backups in the list,

I though at this, but I prefer static config files. This avoids problems
in case the server goes down in the middle of a backup.
