Guys,
I want to backup an Ultra 10 to a remote DDS3 tape
drive, but I don't know what obs size should I use...
Is there any recommendation?
ufsdump 0uf - /dev/dsk/c0t0d0s0 | rsh <remote> dd
of=/dev/rmt/0n obs=?????????
I already used 64b 1024b 32K and 64K but the backup of
100MB data always took at least 10 minutes...
That means to backup 1GB would take about 1.5 hours...
I think it's unacceptable.
What could be wrong? Is it an ultra10 limitation?
Last time, I could backup 8GB data on V480 to a remote
tape in less than 1 hour...
Thanks in advance!
Regards,
John
