If it was that small! A test backup of our /home partition resulted in=20
11 MB of email - and some spurious errors I could not explain to myself..=

Hm. I'll have to reconsider the trade-off between flexbackup=20
(convenient, clever, but no reliable backup verify) against pure afio=20
(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=20
health of a backup tape by using flexbackup after the backup is done. I=20
thought of something like

mt bsf 1 ; afio -t ... /dev/ntape ; [ $? =3D "0" ] && echo "success" ||=20
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=20
errors would be recognized.

Comments?

Best regards,
Dirk
