Advice on disaster recovery strategy using ignite...

[Rui Vilao]

Greetings,

I am trying to implement a disaster recovery strategy for our systems.

Beside the usage of Omniback, MC/SG and MirrorDisk I am planning to use remake_recovery on remote sites.
What is the best way to run to tool on a regular basis?
Shall a keep always a tape in the DDS drive and run this tool once a week from crontab?

Would it be possible to save these images regularly on a different server on disk?

TIA,

Kind Regards,

Rui.

how you implament make_recovery should be based on how important the servers are and how often data on vg00 is changed. if you never modify vg00 then you dont need to run tapes as often, and if it changes regualarly then run it more often, the problem with running the same tape over and over again is they will eventualy get stretched or just go bad, just like any backup routine, alternate your tapes. as for restoreing the tape to a different server this is not a problem either, do a man on make_recovery it will tell you the options to run to genarate a arch.include. modify the arch.include and remove the /dev files then run your make_recovery -r (resome mode) but be sure you run it interactively (-i) this way when you recover to a new system you can modify the host/ip/vg00 disk/ect...

good luck

That is exactly what I have in place for the servers I support. There is always a tape in the drive and I have a cron job run once a month that performs the make recovery. I also save off the lvm info. from /etc/lvmconf by doing a strings on vg.conf files and saving the output. I have found this to be usefull. I have the output from the cron job mailed to me so I can verify that the make_recovery was successful.

I do not make_recoverys with regularity.

I do it every time I update HP-UX ( apply patches). So i Know i can recover boxes from scratch. This plus a tested (recovered) backup is enough. In facts a tested backup is in my opinion more important than vg00.

HP-UX can be installed again, and you can aplly lastes patches. Of course make_recovery is a very good utility.

All that tapes that you are making can be duplicated and sended on disk. And used to recover your box over the network.

See the ignite manual ( i hope someone can tell you where is it).

Set up an Ignite Server and run make_net_recovery,
then you do not have to care about tapes.
With make_net_recovery you can have more than one
generation of you archived client.

Thank you for your contribution.
With your sugestions I have to now a good starting point for the implementation of our disaster recovery strategy.

Kind Regards,

Rui.
