[flexbackup-help] afio error

[Geoffrey G. <ge...@gm...>]

Hello,

I'm using afio to backup to tape. The backup went successfully,
however, flexbackup -list breaks with this:

flexbackup version 1.2.1 (http://flexbackup.sourceforge.net)
/etc/flexbackup.conf syntax OK

How can I get a list of files on the tape to make sure the backup was
successful?
