It would be very helpful to add smart info like XSI Backup Pro does to the email.
Also some option to not replicate if smart indicates that some disk is going to fail. That way the remote replica won't get destroyed if the copy process fails or the disk fails (that hit me just a few days ago).
Yes, you are right. We have already scheduled that feature, still it's not that easy as to impede replication depending on the SMART status, as it's for the main part an statistical analisys matter.
We could add some more flags so that the user can decide at which point to start considering a disk as faulty, still we still have a long way to go improving the main features of (c)XSIBackup, namely: produce backups and replicas, do it faster and more reliably, specially in doing it faster.
