Currently I run amverify after every amdump. My backup window leaves
me enough time to do that and so I have "amverified" that the tapes I
wrote are at least readable. At the particular installation amverify
takes ~30-60 minutes (DDS-3 tapes) depending on tape usage.
I would recommend doing amverify at least once a week to detect tape
errors before it is too late. Doing amverify on another tape-drive, as
Greg assumes, would be even better, but exceeds the budget of my
customers ...
As I am not in place that often, I would like to have some automated
amrecover-run that restores some files of the actual tape.
So it would be like:
1500 amcheck
2200 amdump && amverify && automated_amrecover
I think about including a small DLE containing testfiles, which is
dumped full every run and can be used to be recovered via a script.
Has anyone done something like that?
