I've had that happen (except that I noticed before a drive broke) at least
once, and I remember that Les has also. From what I remember of his
explanation (please correct me if I'm wrong), two physical disks concurrently
positioning their heads can disturb each other (through vibration) in such a
way that one of them returns a read or write error and is kicked out of the
array without the drive actually being in any way defective. I *would*
consider this a shortcoming of Linux software RAID-1.
As Adam wrote, you can easily monitor that. It still is a nuisance, though.

Do the *hosts* show up in the web interface? If not, look at your hosts file
(/etc/BackupPC/hosts or something like that). If so, it could be
* corrupt backups file (/backup/pc/hostname/backups)
* incorrect setting of $Conf {TopDir}
* SELinux problems
* ownership of /backup - if your /etc/passwd is ancient, maybe the UID of
the backup user was changed for some reason?
* web server setup?
* the BackupPC_Admin script is not setuid backuppc
* patched BackupPC scripts (patches done after August 2009) - though your
BackupPC version does suggest it must have been stored somewhere unaffected

That should be unnecessary as long as BackupPC is not running. Err, does the
web interface work without a running BackupPC daemon?

Yes. As Jeffrey wrote, there should be a file "backupInfo" in the directory
which should contain the information you need (including the correct backup
number).
Hope that helps.
