Re: Automated Continuous Log Backups?

I though IDS 7ontape does - open tape - read header - close tape (expecting rewind) - open tape - reread header The reread will fail if you use a no-rewind device certainly for restore. The manual says - ontape rewind devices - onbar norewind devices I always follow the manual.

But at logical log back up time, it only opens the device once which is why ontape -c or ontape -a will work fine with disk files or norewind devices. Then only downside is that you have to remember to manually rewind the tape cartridge before attempting to restore. For all other ontape modes REWIND devices are definitely required. Art S. Kagel
