When I open the bkf using the NTBackup utility, it does not seem to
recognise the latest two backup sets (of 3 I think).
Any ideas how I can restore the latest set?
Note that I have a demo version of a BKF recovery program that does seem to
recognise the hidden sets, but it costs quite a lot to buy it and I guess
there is no guarantee it can actually restore the data.
BTW, let this be a salutary lesson on the hidden dangers of using
special-format backups. For disk-to-disk backup anyway, I would always advise
the use of systems which backup in a 'visible' file format.
Cobian Backup and Lazy Mirror are recommended.
