For big backups, cron mail isn't very light (1,2MB of backup log).
If it was that small! A test backup of our /home partition resulted in 
11 MB of email - and some spurious errors I could not explain to myself...

From the Flexbackup ToDo list from site:

"A shorter summary status that's better than doing
egrep "(error|of set|Backup of|written)"
of logfile.  Needs to handle all configurations...."
Hm. I'll have to reconsider the trade-off between flexbackup 
(convenient, clever, but no reliable backup verify) against pure afio 
(to do file searching stuff on my own, fiddle with the command line, but 
being able to guarantee that the backup tape is at least readable).

Is there someone how found a procedure to _guarantee_ the physical 
health of a backup tape by using flexbackup after the backup is done. I 
thought of something like

mt bsf 1 ; afio -t ... /dev/ntape ; [ $? = "0" ] && echo "success" || 
echo "failure"

If one does not rewind the tape, this should create a file list and read 
the complete latest backup from the tape for this. Any physical read 
errors would be recognized.

Comments?

Best regards,
Dirk
