Hello. I am seeking advice on the proper way to backup my Alphastation.
I have a single Alphastation 250 4/266, with a 8505 8mm tape drive attached
in a Storageworks pizza box. I have been backing up my system, while logged
on as root, using the following commands:
Tape #1:
dump -0unN /dev/rz0a
dump -0un /dev/rz0g
Note: /dev/rz0a is the / directory
/dev/rz0g is /usr
Tape #2:
dump -0un /dev/rz6e
/dev/rz6e is /ibm/pe
Tape #3:
dump -0un /dev/rz3c
/dev/rz3c is /big
I am not logged on at the "console" level when I issue these dump commands.
My questions are:
Is my backup method valid? Am I putting two dumps on the same tape properly
using the dump -0unN method? Should I be at the console level or is being
logged as root okay? Is there a method that I could have the computer do
this for me at night, as opposed to me issuing the commands by hand? Is
there a backup package that could help me do this properly? Could all these
directories fit on one tape?
I know these are a lot of questions, but I worried that some day I'll lose
some files or a disk, and not be able to restore them properly. The sage
advice of longer-term users will be gratefully accepted, and I will summarize.
Here is a report of the df -k command for my disks:
hopland> df -k

Thanks for any and all help,
Colin Brooks
