Hi,
We're planning to relocate/shift our datacentre in a few months' time.
I realized in our DataProtector Centralized backup, we only backup at filesystems level &
looks like bare metal recovery is not an option currently.
The relocating vendor/mover told us from their years of relocating numerous datacentres,
the parts that's most likely to fail (besides connecting up cables/parts wrongly) are :
a) hard disks
b) Power supply components
For (b), we'll have the hardware vendors' on standby with spares.
To take precaution against system disk failures (ie root & /var partitions for Solaris &
HP-UX & Linux), there's a few options :
a) in Solaris, can do "ufsdump 0uf outputdump.dmp /" (for root) & burn the dump
file into a DVD (as some of our Sun servers do not have a tape drive). Or does
anyone think it's better to dump it to a 4mm DAT if one is available
b) create a "flasharchive" in Solaris - can someone give me the command to do this
as I once tried to do it for root partition & ended up with a superhuge file. I don't
know how to do this for Redhat (4.6 & 5.1)
Between option (a) & (b), which is better? For Solaris, option (a) requires us to still
create a bootblock on the disk after recovery, so is option (b) better? I'm looking for
something which allows us to quickly recover the system to a multiuser bootable
state. For MS Windows & our VMWare recovery (to the usual multiuser state), I'll
create another question (but you are welcome to reply). Looking for quick & easy
recovery of / & /var for Solaris & Redhat (I've got the answer already for HPUX).
For data partitions, they are too huge I simply have to rely on DataProtector (which has
its proprietary format & can't be restored via a local tape drive) to restore damaged
disks. Of course if the Gigabit network have a problem after relocating, we simply can't
do any restore & have to wait till the network is up or is there any better option?
