Following my recent summary (how to dump a DEC file system onto a DLT
hooked to another machine), Lucien Hercaud reminds me that vdump uses a
default block size of 60k, but that dump uses a default block size of 10k.

Thus, if dump is used, it is probably wise to perform the remote backup
thus:

# rsh DEC -l root -n "/sbin/dump 0f - /usr" | dd of=/dev/rmt/0cn obs=10k

so that you don't have to mind about the block size in case of restore.

It is quite possible to use:

# rsh DEC -l root -n "/sbin/dump 0f - -b 32 /usr" | dd of=/dev/rmt/0cn
obs=32k

but in that case you will have to specify the blocksize (-b 32) to
restore.

Cheers,

Jean-Loup
