Hi,

Exactly how many backup's to external media are required in order to
recover a broken HMC?

A colleague seems to think that 2 seperate backups need to be in place.
A Critical Console Data backup made to DVD and a profile data backup
to DVD.

I was under the impression that if you backed up your profile data to
disk, the CCD backup would include this.

Is it necessary to schedule these 2 backups to seperate media?

Thanks.

When you perform a profile backup it saves it to
/var/hsc/profiles/system-name. When you do the CCD backup it gets dump
to DVD.

In spite of IBM recommeding this, I believe that manual backup of
profile data is not so necessery because a backup file having the
profile data is created by default at the time when HMC is first
connected to the managed system. On each subsequent reboot of HMC this
default file gets updated with any profile changes, if any have
occured. Still this can be backed up and multiple copies of this file
can be maintained. Any one copy of these can be used for recovery.

On the other hand CCD backup is important as apart from backing up HMC
configuration, it also backs up the /var/hsc/profile/MT-MDL*SN
directory containing profile backup.
