I have created /etc/exclude.rootvg file with the following entries. Please guide me if i am doing ok

^./usr
^./important_dump
^./sapmnt/D01
^./oracle
And i am backup up system with the command

/usr/bin/mksysb '-e' '-m' '-V' '-i' /dev/rmt0

Am i doing right and would i be able to restore my system back if i loose anything?
Thanks

The mksysb only backs up the rootvg volume group. If you do a man on that command you will get a good idea of how to use it.
Hopefully you only have the OS in rootvg and nothing else. If you do then you don't have much to exclude if anything at all. You didn't say but you definitely need to have Oracle in its own volume group and any other apps too. I even put the Oracle backup files in their own volume group separate from the Oracle app stuff.

Do you have just the OS in rootvg?

Good luck.

Hi,
Thanks for your reply. Can you tell me that how to check whether i have my OS on root vg or not. I told you that i m very very new in using AIX. So i must be sure that this is not backing up any of the above mentioned file systems and it will only backup root vg. SO, if i have many other things on root vg and i want to exclude them and only want to backup OS, what should i do?
Thanks

Salman

Hi,
Please see the file systems in my rootvg in the attached file. You can also see the output of backup information which i took on the tape and you can see the size of this backup. Backup also takes more than one hour on my development system, and on production system it is taking 3 hours. Why is it taking this much time and why backup size is 27.5 G and compressed size on tape is 19G
